I finished up my Franken-KGSS last night and wanted to thank everyone involved! I'm running right at 35 W (just over 12 mA per device * 350 V rails * 8 devices, compared to 24 W ? of Justin's KGSS and the 40 W plate dissipation of the KGBH) and it sounds amazing. I'll get pics up once life settles down. It also serves as a rather nice space heater, as if we Texans need those
I've been listening with the Koss ESP-950 and want to reiterate what a special headphone these are... my only complaint at this point, is the ridiculous amount of bass ... that's compared to the HD-650s too... I've been futzing with my cartridge alignment, so that could be part of it, but still... reminds me a bit of the Denon D5000 (which is not a compliment). I'm going to add some gain on my phono stage and start tuning my system around the new addition, so I'll keep you guys updated.
The nice thing is, my seperate psu is adjustable up to 500 V, so I can play with the KGBH as well!
