Hi – Fi ‘s Green Credentials: More Hype than Myth?

Ever sine electronic or e-waste became an environmental issue due jour, should we hi – fi enthusiast remind everyone again our green our hobby is like we supposedly did 10 or so years ago?


By: Vanessa UY


After seeing a BBC documentary about the sheer amount of plastic waste piling up on the Pacific island of Midway, especially plastic housings of pre-loved personal computers, I asked myself: “Why aren’t there hi – fi related parts out there like the synthetic wood used on good hi-fi speakers?” Another environmental group – Greenpeace – was recently (or is that perennially) vocal about the e-waste issue especially with regard to substances that are dangerous to human health like lead, cadmium, and arsenic used in a typical PC, mobile phones and other mass market PC related product. (Should Greenpeace also lecture to Iraqi insurgents not to use e-wastes as electronic triggers for their IED ‘s, since it’s dangerous to the health of US troops?) But seriously, has anyone wondered why hi-fi enthusiasts are not chucking their pre-loved gear into the garbage bin with similar frenzy as the PC crowd?

Though there are people who refurbish pre-loved PC ‘s, usually these are donated to impoverished parts of the world to promote computer literacy. The person doing the refurbishing is likely not the PC ‘s original owner. When a hi-fi gear becomes obsolete or worse yet “give up the ghost”, their owners either give them away to someone who is new to the hobby (usually a sibling or a very close friend) or cannibalized for the still functional parts if its busted beyond repair. Hi-fi enthusiasts regard their gear with such reverence that the only time you see their audio systems shattered and scattered in the middle of the street is when a 2,000-pound JDAM strays into their listening room. A friend of mine – an unabashed vacuum tube amplifier enthusiast - has his e-mail inbox filled to the brim with request for vacuum tubes, which have lived out their useful lives to be used in an art installation. To me, I even wonder if this is environmentalism or fanaticism.

Even though we never throw away our gear even after becoming obsolete (I’m even hanging on to my great grandmother’s 78 R.P.M. shellacs), our hobby can’t be considered completely green. Those “old school” audio amplifiers are very power hungry – even on standby. But given today’s high cost of grid electricity, most of us are either embracing photo voltaic – storage battery energy systems or are now too busy to listen to more than four hours a week on our audio systems. At least my pre-owned audio interconnect cables are not choking a flock of albatross in the middle of the Pacific.

Have Video Will Travel

Audiophiles are forever resentful when state-of –the-art video technology become their despotic overlords. Have we seen this coming?


By: Vanessa Uy


Ever since George Lucas tackled the problem of insufficient sound quality that exists in an overwhelming majority of commercial movie theaters not doing justice of the "soundtrack" i.e. the musical score and sound effects of his masterpiece “Star Wars” back in the late 1970’s. By establishing his THX program and together with Dolby, finally made a new dimension available to the moviegoers – namely good quality sound. I do admit that most horror movie’s “scariness factor” can be dramatically increased when the desolate sonic ambiance of a quiet cemetery or a haunted house can be faithfully recreated inside a movie theater. Thus the excellent results of George Lucas’ THX program was hijacked by the consumer electronics industry to sell their “Home Theater” concept. Maybe “Home Theater” is much easier to sell because the consumer electronics industry can’t figure out how to include pimps, hookers, and cocaine peddling drug dealers when they tried to sell us “Home Disco” back in the late 1970’s.

Despite concerns over high electricity consumption and the ensuing enlargement of my personal “carbon footprint”, my personal disdain – make that cynicism – over the “Home Theater / Surround Sound” industry is largely to my very personal tastes and aesthetics. Most of the “multimedia stuff” I watch domestically are what a majority of people would consider “old”. To be watching a DVD of that old Frank Sinatra version of The Manchurian Candidate or an episode of Coronation Street just four feet in front of a 3,000 dollar 150 inch plasma screen with a THX certified surround sound system is a tad too overkill for me.

The audiophile community has since harbored resentment, not only because the home theater industry made their hobby more expensive than it actually is. But also by actively – I mean actively - perpetuating the fallacy that a good audio system must / should have a large video monitor that costs similar to a budget Japanese car and is surround-sound capable with speakers littered all around the listening room. Now, the pimps, hookers, dealers, and junkies (even Osama Bin Laden?) can now come to your home via the state-of-the-art video monitor. Ok, I’ll admit that it’s a technological “Stepping Stone” to Star Trek: The Next Generation’s “Holodeck” technology. But should we the consumer foot the bill for these companies R&D development? We’re not walking banks you know.

In my opinion, the consumer electronics industry has been exploiting the “video bandwagon” for one thing only – it sells. So if your selling a bona fide “Luxury Item” that most people can really do without, you should exploit the sense that they use most even if not conscientiously – their vision. Video monitors sell so easily because overwhelmingly most people use their sense of sight more than they use their sense of hearing. The “latest technology” catchphrase being used as a unique selling point describing the improved quality of the video monitors that these companies are selling are easily manifest by sight alone. The old adage of “to see is to believe” really applies when it comes to touting the improved quality of the latest models of video monitors that they are trying to sell.

The only thing that bothers me though is the way today’s consumer electronics “marketing men” use the old adage of “to see is to believe” in perpetuating the myth that sound quality is unimportant. They rely on oscilloscopes and PC compatible audio analyzers to show – or make visually manifest - how excellent their latest audio amplifiers perform. They do this even though a tube-based amplifier using technology form an era when Dwight “Ike” Eisenhower was still the president of the United States is more beautiful and real sounding than their latest model. Home Theater as a concept is really great, but it can’t quite compete yet with this thing we call “real life”.

Romancing Black Gate Capacitors

What is it about Black Gate capacitors that installing them in your audio amplifier’s power supply always result in a dramatic improvement in sound quality, or is the perceived improvement just in our heads (and ears) as the current wisdom of meter reading audio engineers attest?


By: Vanessa Uy


Anyone who practices DIY (Do it Yourself) hi-fi surely have come across with one of the audioworld’s most revered electrical components – Black Gate capacitors. Often used as power - supply filtering capacitors in many high – end power audio power amplifiers. Black Gate capacitors especially the “lower cost” Japanese versions manufactured by Rubicon had since become available - as replacement parts sold in electronic parts retail supply stores - to the DIY hi-fi hobbyist. And since their use have sparked the debate between subjective and objective ways of assessing the sound quality of an audio power amplifier. But as hi-fi enthusiasts later knew, other “sections” of the audio chain like the preamplifier / signal controller’s power supply section of a typical audio system. And even the power supply of the CD / DVD or other front - end player will benefit in improved sound quality when their "stock" power supply capacitors are replaced / augmented with Black Gates. But before we proceed further, here’s a brief primer on what are Black Gate capacitors.

Black Gate capacitors are a premium grade of electrolytic polarized capacitors specially constructed as to have a much lower effective series resistance (ESR) or impedance than cheaper electrolytic capacitors. Probably designed and marketed during the latter half of the 1970’s, Black Gate capacitors were probably built by their creators for use in high frequency switching mode power supplies due to their low ESR. But this didn’t deter audiophiles, DIY hi-fi enthusiasts and tweakers from using them on the linear power supplies that convert the ordinary 60 Hz AC household current into the DC used to power audio equipment because it made them sound good. During the late 1970’s and throughout the 1980’s, almost all Black Gate capacitors were manufactured by a Japanese electrical and electronic manufacturing concern called Rubicon. Rubicon became explicitly linked with these capacitors because at the time – especially in the 1970’s – Japan was still a “low wage” country which was a bit later replaced by Hong Kong and later Taiwan as the low cost production capital of the world. Because Rubicon Black Gate capacitors were relatively cheap, hi-fi enthusiasts freely experimented with them without the feel of burning their wallet if they accidentally “cooked” one. Thus Rubicon Black Gates became the raison d’ĂȘtre of DIY hi-fi.

But by June 1995, Rubicon – the Japanese manufacturer of Black Gate capacitors, has ceased production of the famed premium grade electrolytic capacitors. The move was perceived by hi-fi enthusiasts as being similar to Porsche quitting the manufacture of the 911 because it can’t make them as expensive as Ferrari’s megabuck sports cars. Keith Parker of Rubicon, London, said: “the Black Gates were a 20 - year - old design (in 1995) unsuitable for mass production, so they had to be hand assembled. Many of our newer electrolytics such as PS2, YXB, and YXF perform every bit as well when used properly”. In my experience so far, Rubicon’s PS2, YXB, and YXF electrolytic capacitors are often used in mid-priced (US$500 – US$1,000) DACs (Digital to Analogue Converters) manufactured in 1995 and beyond. Despite of Rubicon ceasing production of Black Gate capacitors, Jelmax, who own the Black Gate design, still manufactures the capacitors albeit at prices much steeper than the Japanese Rubicon versions. These pricier version of Black Gates were often used by Audionote one of the most respected names in tube based audio amplifiers.

In practice, hooking – up Black Gates to your system really does wonders no matter what kind of music you like. I mostly listen to guitar based heavy metal music at unamplified drum kit sound levels, and believe me, they do tend to sound as if the musicians are in front of you. Poorer recordings are redeemed by making them “listenable” over prolonged periods and can even make you conclude that this particular sound is what probably the record engineer / producer (or the artist) intends it to sound. Black Gate capacitors are probably the only tweak you need that makes listening to music more pleasurable without taking psychotropic drugs or anything similar. The bad news is if you bought hundreds of dollars of audio analyzing equipment like the latest ones by Hewlett Packard which can be connected to your Windows Compatible home Personal Computer, the output waveform of your amp remains the same before or after tweaks despite what your ears tell you. Believe me, existing audio analyzing equipment like the one I just described can be “stone deaf” when it comes to sound quality – unless you’re looking for “rogue submarines”. So better spend that money on other stuff like CDs, or give it to charity if it is really burning a hole in your pocket.

High Definition Multimedia Content Anyone?

Does the latest generation of downloadable high definition (HD) multimedia content worth viewing and hearing in our dedicated HD-ready home theater set-ups?


By: Vanessa Uy


Nowadays, HD (high definition) multimedia content (audio and video) that can be downloaded from the net via your own home PC is of such quality that most of them-if not all- deserve to be viewed and heard in your existing HD-ready home theater system. If you’re like me – as most of anyone in the audiophile community- who thinks that your PC and home theater system should not mix (i.e. share the same outlet) because the former can degrade the performance of the latter must face a somewhat insurmountable problem. How to send that high definition movie -with the attendant surround sound data- that you legally downloaded from the net, from your PC to your home theater set up?

There are a number of systems in which you can deliver/send that HD content you have downloaded from the web. One of them is a relatively new technology - which uses your mains/ac line to send your data. Consumer devices that utilize this principle of sending data only came to the market near the end of 1997. So the ones currently available in your local AV/computer store not only works better, it’s likely to be cheaper as well thanks to almost ten years of progress. This has the advantage of avoiding the clutter that can be created when installing the necessary data-transfer cables. The problem with this system is that if you own a state-of-the-art home theater system, you probably bought with it a very good dedicated mains/ac line filter to maintain the consistently good performance of your home theater system while protecting it from electrical interference and lightning strikes. The same mains/ac line conditioner blocks the digital data that you intend to send down your mains/ac lines. Another way to send your multimedia data while avoiding the clutter of additional cables is via WIFI or wireless data transfer systems. The current generation of WIFI systems can easily handle the bandwidth required in sending HD multimedia content but will be easily vulnerable to signal interference especially if you use your mobile phone while using the WIFI system. If you want to maintain signal integrity while transferring HD multimedia data, Ethernet networks are a good choice. A word of warning though because these systems involve additional wiring if you are squeamish about the clutter factor. The latest “Cat 6” or category 6 high speed Ethernet connections are a good choice and could be a very good investment because of it’s future proof status. This is due to the fact that it can handle data transfer speeds of 10 Gigabits per second and anything faster is yet in the far off future.

I just hope that the circa-2007 PC and AV convergence will bear the fruits of a better audio and video quality that doesn’t cost the earth. Unlike the divergence of 10 or 15 years ago were hi-fi manufacturers have the luxury of producing and selling obscenely expensive AV equipment with impunity. Since all of our present media formats are digital in one form or another, convergence is inevitable due to the fact that digital data is both robust and universal.

Will “We7” Save the Music Industry?

Will Peter Gabriel’s “We7” make music downloads equitable for musicians, music lovers and record label executives?


By: Vanessa Uy


Slated to be launched on June 2007, Peter Gabriel – supported “We7” not only promises to please musicians and record label executives but also provide a legal and legitimate music download service that’s free of charge for those who have acquired a taste of Napster’s “poisoned fruit.” The music downloads on “We7” are free in the sense that music lovers and/or fans don’t have to pay a single cent to the site. The site itself uses the revenue created by the adverts on the site itself to pay the musicians and record label executives according to how often their “works” are downloaded. Another “Bolshevist” feature of this site is that users are encouraged to share the music that they downloaded to other music lovers so that they will also “fall in love” with “We7”. To me this is a far better proposition than Digital Rights Management or DRM.

Sound quality issues aside, the downloadable music phenomena on the web has the advantage of worldwide accessibility that is quantum leaps ahead compared to traditional music distribution systems like record stores-even specialist ones. For example: the freak commercial success of Ed McMahon’s “Star Search” alumnus Tracey Spencer during 1989 has been a boon to music lovers everywhere who are into the politically-correct-side-of-altruism message. But a follow up of something similar has been slow in coming. The posthumous success of Nusrat Fateh Ali Khan to American MTV audiences in 1998 was much delayed due to the slowness of traditional music distribution systems back then. Even though a handful of adventurous music lovers has been enjoying the music of Nusrat Fateh Ali Khan in the US since the mid- 1980’s. If you seek to introduce a more adventurous variety to your musical taste, its much easier today via on- line music downloads. The Turkish-German R&B sensation Muhabbet became well known via the Internet. Muhabbet means to talk to each other in Turkish, has gained enough fame for his talent to be noticed. And now, Muhabbet has become UNICEF’s goodwill ambassador. Interested parties can contact Muhabbet at www.muhabbet.name.

I just hope that “We7” doesn’t forget the sound quality aspect of their site because as a legal music download site, sound quality can serve as a unique selling point for a site that supports the welfare of hardworking musicians and others in the music biz. As Peter Gabriel is a humanitarian-at-heart, the extent of “We7’s” benefits could put a major dent on extreme poverty. But for now, on line music download services like “We7” provides a level playing field for musicians anywhere in the world who are very talented but still lack the recognition they rightfully deserve.

Oral Sects

Do audiophiles have a special language of their own, or is it just a symptom of the perception on how skeptical people see as the persistent delusion that everyone of us perpetuate on a daily basis?


By: Vanessa Uy


Ever since I’ve learned how to read and write, I’ve always had a closeted fascination for anthropology. It might be because there’s been a consensus in the anthropological community of late that of all the 6,000 languages documented globally, only half of them are taught or passed on to the next generation. Is this a foreboding that the audiophile community is in danger of waning away into oblivion?

The terms that are also used by those- analytical- bunch called “engineers” whether of the electronic, acoustic, or of the communications persuasion will not be discussed here to avoid duplication. Here, we concentrate on the more subjective terms that can only be assessed by first hand listening.

One of these subjective terms is called “audiophilia nervosa” which means someone is more concerned on how there favorite musical piece. For example Beethoven’s Ninth/Ode to Joy will sound on a certain brand or audio system set-up as opposed to whether the music in question is well-performed or inherently well-composed in the first place. To me, this is the root cause of some audiophile’s apparent dissatisfaction of their hi-fi equipment they already have. Thus spending ungodly amounts of money in perpetual equipment upgrade in search of that “perfect sound”. If you think you are suffering from this sort of mental illness, better take a long hard look at your record/music collection.

Musicality is also a very subjective term. It means when certain stereo equipment can replicate not only the sound of the recorded music being played but also the emotion the artist or performer is trying to convey. As opposed to sounding just like a collection of electronic equipment and speakers. A certain audiobuddy of mine has a rig with a penchant of replicating the sound of a heavy metal band drum kit, albeit a drum kit being played in an acoustically treated space. Civilians/non-audiophiles hate my audiobuddy’s system for the reason that they can’t hear the tweeter working. All they hear are various cymbals, rim shots, and drum skins. Mind you these are the same “civilians” who like their tweeter to sound like a cricket or a cicada screaming its guts out.

Imaging and soundstaging is more akin to using visual descriptions to gauge your audio system’s capability. The individual sounds comprising a sonic ensemble. And how accurately your audio system differentiates them in their respective locations in space is known as imaging. While soundstaging is about how your audio system projects the sum total of the individual sound images from left to right of the speakers or to the front to back of them. Soundstaging usually applies to traditional two-channel stereo where the performance is happening in front and this is the way we (my audiobuddies and I) preferred it. The lead guitarist never ever sneaks up behind me (carrying a 120 lb. Marshall Amplifier and speaker stacks) in real life.

To me, the one that takes the cake is the term called “British sound” or to describe a sound system as “British sounding”. To me, it might be because the Brits have been making hi-fi kit for a much longer time and in greater variety when compared to other industrialized nations. Or more likely, it’s because the typical British audiophile has a certain size and construction of listening rooms: medium sized in global terms, wood floored, and with walls made of plaster or brick. They also prefer a more upbeat sound, or they prize the sense of pace, rhythm, and timing in their audio systems.

So, there you have it. Feel free to drop us a line if there’s anything that we missed, or if you have a first hand experience about these mysterious audiophile phenomena.

Of Hi – Fi and Humanitarian Relief

In the service of informing those who ask while risking in reiterating the obvious, the article contributors of this blogspot who are audiophiles DO help the unfortunate. Do our doubters care too?


By: May Anne Uy


As one of the contributors who’s been a hi – fi enthusiasts for more than ten years, I may currently own a stereo set-up that helped CARE and the International Rescue Committee (IRC) back in August of 1998. At that time, The Third Annual Summer Against Hunger was underway. The event’s underwriters were lead by The Cable Company (www.fatwyre.com). The underwriters donated up to 10% of my stereo system’s price to CARE and IRC. Looks like my pride and joy donated 300 US dollars to CARE and IRC back in 1998.

Also, each of us has around 300 US dollars each currently invested in Muhammad Yunus inspired microfinance programs in our country. Like the Sustainable Microfinance Services for the Filipino Entrepreneurial Poor which has been of great help to the small farmers living in rural areas. And also a good reason for going out to the country for the program’s biannual “stockholders” meetings.

Speaking of Burma’s / Miyanmar’s military’s bloody crackdown on dissidents, the two Burmese families presently renting in our apartment had been granted “rent amnesty” for three months. This move –to me - is like hitting two birds with one stone. Because I can help these families alleviate their suffering while exerting moral pressure (a politically correct equivalent to sticking it) to the Burmese military junta by “harboring dissidents”.

Lastly, I purchased that John Lennon inspired Darfur Crisis Relief double CD album even though I liked only three of the artists featured on that CD. I hope Amnesty International will do something about this. By the time the crisis in Darfur ends, I’ll still be very hard – to – please musically that is. I’m just a sucker when it comes to good causes.
