sorry for the messy wiring :P

 

surprisingly very very very clean, almost no notice-able noise when power on!! Even with low impedance earbud ex888lp :thumbup:

 

burning in using STS Digital Burn In CD, any high impedance headphone (>=300ohms) to recommend?

weird pairing with ATH-AD700...I believe i really need a dark/warm sounding high impedance headphone.... sh*t

good idea...maybe should have two separate power supply ? :grin:

 

Ideally I would prefer to have 4 cases.

 

- Left channel

- Left channel power supply

- Right channel

- Right channel power supply

 

That would be an ideal monobloc headphone amplifier. If you are very free, you can consider.... but let me audition when you completed. :D
