Just my 2 cents on this... After trying them both, I found the hd800 to be remarkably better, if you are willing to spend 1000$ on headphones.

Hi, it's me again. Managed to rewire the tubes and now there is sound on both channels. However, it is not amplified and it is quite distorted and the lower frequencies are missing completely. Any pointers on where to start debugging? I have a 10k pot as the volume knob. Measured...

Just left them floating :) Now I'm rewiring the tubes

Question. Should pin 1 and 6, 2 and 7, etc. be connected at both tubes? I wired the thing as pin 1,2,3,4,5 to one tube and 4,5,6,7,8 to the other.

Hello everyone. Managed to assemble everything, but hearing no sound from the amp. I'm measuring 13V between pins 4 5 on one tube, nothing on the other. However, the 0V tube doesn't heat up. Another measurement between the MOSFET gate and source: 3,43V on the good side, 48V (!) on the other...

I'm interested in this too, OP. What are the requirements from the amp? Wattage/Voltage/Amps, etc?

I only tasted those bargain blends and they were kind of awful. The dearer ones taste better? :)

Okay, thanks a lot :) Now I finished soldering, waiting for PSU to arrive. By the way, I saw that the Cisco 48V one is more or less precise to 0.1 Volts. Is that punctual enough for hi-fi use?

Hello there, After studying the stripboard layout, it is quite unclear to me where the Q1/Q2 Mosfets go. Are they connected to the R2, and R8 resistors in series?

They sound awesome as they are without amp, but I'm building one at the moment :D It will be a "starving student" tube amp.

Eventually I bought a Sennheiser HD580 :)

Thank you all for your input, I'll check these out!
