Steve Eddy, who designed this, formerly of Q-Audio Cables on Head-Fi, designed a horrible, senseless, transformer-based circuit here in his EMAC amp. Garbage.
Steve assembled my Bellatone Audio Beta Twenty Two and Sigma Twenty Two (main amp and power supply boards designed by Ti Kan of AMB Labs, the best headphone amp and power supply in the world that you can buy or build as a 2, 3, or 4-channel balanced common mode noise rejection like mine, or even a stupidly foolish 6-channel) which was a cost no object, luxury, custom PCB upgraded, full speaker amp-size dual chassis with 1000W dissipating heatsinks on all 4 sides, custom designed front and back 5/8” thick T-6061 anodized aluminum with laser bleached graphics and nickel-plated end caps and matching volume remote which controls the DACT stepped attenuator. He had my supplies for a heavily stressful 18 months of which he said he was working on it, only to find at the end he did nothing for 9 months, then spent 1 week on it, nothing for another 8 months, and spent 2 more weeks finishing it. So if you want reliable, this is not the company to deliver. (See all my amp and system photos below under replies.)
Oh yeah, not amp related but important: he also created a fake Obama birth certificate (to try to prove the idiots who think Obama wasn’t born here are wrong, and they are all absurdly wrong) and mailed it to Tali Orlit and it became one of the 3 main fake birth certificates discussed throughout the world. Let the FBI ask me. I might still have his pictures to prove it somewhere on my old PC or in a photo library.
Steve, if you find this, e-mail me. I’d love to see what you’re up to these days (seriously, no joke), if you’re not in federal prison. I hope you still have my email after all these years.
