Hey guys,

Could somebody tell what is the difference between V1 and V2 revisions of HP4 preamp?
The only differences I was able to find so far:
V1:
Max output power: 150mW
Power: 16V
THD+N: 0.002%
It has metal knobs and more sturdy rear jack sockets.

V2:
Max output power: 130mW
THD+N: 0.0025%
Power: 12V
Plastic knobs and the same front/rear jack sockets.

Is there something else? Which one you think is better?

Thanks,
Vitalii
