Vicki looks very matronly there :)

It's the new reading glasses.

Gene's O2mk2/007tmk2 sound nice. I find the O2mk2 more comfortable than the O2. I don't have the O2 here to do a comparison. That will have to wait until Saturday assuming we ever leave Houston. Our initial flight was 6:30 pm Central time. We then got on a 9 pm flight that is delayed until 11:20 pm.

Man, that sucks. Sorry to hear that the travel plans are so hosed up. And don't let that penguin dude hog the DAC this time. :)

You guys/gals sure look like you know how to travel... hope the rest of the trip goes smoother :prettyprincess:

Wow that really blows, but at least you're making the best of it there. Nothing like friends and headphones to make flight delays a bit more bearable. See you all Saturday if not tomorrow!

WHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

Stephen, who is sitting next to me, asked me to tell you that he has managed, through the marvels of modern technology, to log in and post from Fairfax.

WHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO :horsey:

Wow you guys busted out the SR-007 at the airport. Niiiiiice ;D:prettyprincess:

Too much amazing gear to begin to talk about. One post for now: seriously amazing K1000 homebrew amp (built last week). This amp uses large Russian GM70 transmitting triodes as output tubes. GM70s are driven by 6BX7 television vertical amplifier tubes from the early 1960s The two tubes are coupled by interstage transformers. It uses dual high-voltage power supplies, using mercury-vapor rectifiers run into LCLCLC filters. The GM70 filaments are powered by a standard industrial "brute force" power supply. Per the builder, Frank Cooter, the circuit is straight out of 1937. All I can say is it sounds damn good with the K1000s, beautifully natural with a smooth high end (loosing that sometimes digital feel the K1000s treble gives), and beefy, but clean bottom end.

The builder and his amp:

I haven't yet had time with the famed emm labs/zanden combo, but the Cooter amp (it has no name) pretty much blew me away.

IIRC, Frank Cooter also built a DIY amp for the RS-1s during last year's Head-Fest.

What's that DIY-looking wooden headphone?

And I love the space cadet look Ken has going on.

HEAUDIO 1.3 stat phone, IIRC.

By god that HEAudio phone got fugly. It was pretty shitty looking before, and now it just looks like firewood.

Agreed. Methinks they should have used darker wood/materials all around. The new black SR-007 MkII, OTOH, looks fantastic.

Nice meet! thanks for the pics.

OK, how about more impressions please!!!!!!!

I see 3 Cooter amps, is that correct? Comments on configuration, etc...

thanks!

I think what you're seeing is all one amp, 2 separate power supplies tied to the central amplification section.

Dual mono supplies with a single amp section. I like that he used GM70's in a headphone amp as Lamm is charging 100k+ for a similar amp for speakers... :o
