Possibly the most ambitious thread ever started on Head-fi.
Goal: To honor those who have made it technically possible to enjoy building our own headphone products, created in our own image, with whatever parts we could scrounge (or wildly overspend on), enduring the horrors of casework, resulting in (both) the "Thrill of Victory and The Agony of Defeat".
The REAL thread (this just to discuss how to form, qualifications, vote / autocracy, categories (OR, just amps?)).
For meritorious acheivement to the community, there should be a lifetime membership (for which we need to figure out how to pay).
To wit: First cut at categories:
Amps
Source
Cables
Headphones
OR, maybe NO categories - just overall body of work?
Founding fathers:
First nominee: Chu Moy
HeadWize - Breaking News
Body of Work: Without Chu (founder of Headwize.org - headwize Resources and Information. This website is for sale!), there would be no HF, as this was to be an interim respite during a Headwize outtage. Others can better tell the tale, and I remember a Jude post from back when, though I may have poorly paraphrased. Father of the most built amp ever, simply known as the CMoy.
In no particular order...
Tangent
www.tangentsoft.net
Body of Work: The first site dedicated to DIY, from the conceptual to the practical, as well as the first parts shop, not just a few boards. Along with a team, gave the DIY community the META42 (Morsel, Eric, Tangent, and (FIFM)), and later the first mini amp, he has been there from the beginning. Always available to help DIYers troubleshoot their builds.
RickCR
OK, I did not get along with Rick, at.all., BUT, we cannot deny him recognition. Sure, he could be further down the list, but look again at the linked list he created under the DIY rules sticky - it showed he cared about us, albeit he ruled that care with a rather iron fist. If it is too distatseful, consider this like lancing a boil. A really OLD boil.
Pete Millett
Pete Millett's DIY Audio pages
Body of Work: I don't know if anyone has more designs built than Pete, and he has given them all freely, with entire 2nd and 3rd generations of his designs prospering. I have owned HA-1, HA-2, and think the HA-4 his most intriguing design ever, with schematics / BOM available. The outright gifts of the MillettHybrid (now MillettMax, and MiniMax) as well as the Millett Starving Student (Most furiously built amp in headphone history) are just altruism incarnate. I still own and use a MillettMax. Thank you, Pete.
Kevin Gilmore
Body of Work: Dr. Gilmore has given us designs in distinctly different worlds, Dynamic (Dyna - High, Mid, Low) and Electrostatic (Current Domain, KGSS, and Blue Hawaii). Dynafet and other new designs are coming, and while fewer build these designs (mainly due to the unobtanium of parts), the designs are superior, but demand a bit more capable (or at least determined) builder. Willing to help troubleshoot issues where given enough data.
Ti Kan (Amb)
AMB Laboratories DIY Audio Site
Body of Work: Ti has given us outright the m³ (which was a group development, with Headfi feedback, and Morsel teaming on design). After that was the e12 muting circuit, used by several other designers, the beta 22, and sigma PSU. All the technical pinnacle of solid state (sand) design. And, he runs a first class parts shop for boards and hard to source / matched parts. Always available to help DIYers troubleshoot their builds. he has also branced into DAC with the y1, showing range and versatility. (Note: yes, speaker amps to, but this is strictly headphone).
ps: If only we could get Ti more into tubes...
Alex Cavalli
Cavalli Audio
Body of Work: A relatively new player, but quite prodigious with CKIII, SOHA(II) and Bijou. These designs are outstanding hydrid and all tube designs, equalling any commercial designs available, and bettering most in the ability to roll tubes. Very hot on continuing new versions of the existing designs, and a known killer amp just about ready for release (Stacker II). Always available to help DIYers troubleshoot their builds.
Colin Toole
beezar.com welcome page (FIFM)
Body of Work: Colin has gained most of his following from the Millett Max, and MiniMax, but is now als working shunt regulators (parts of upcoming amps
, as well as some DAC work). May be a bit early for full inclusion, but certainly on a trajectory for eventual inclusion.
Ok, that is a start - alpha or omega, as I have pitched the idea. Pity I don't have an editable version of MindMap to draw a 'Connections' like diagram of DIY designs, and how they have evolved. One fact is that this has become a multi-million 'business' of it's own (some argue taking sales out of MOT / manufacturers), but it will live here, or elsewhere, long after the current players transition over time.
And, we ALL owe these guys for showing us the way.
Please, add anyone I forgot.
