Audio-gd Master 1 preamp any good?

  A new preamp and DAC is coming out soon.  Take a look at the Chinese web page:

I believe the HE designation means a balanced power supply, which is why they are so much bigger.  If the new model is an HE-1, it is probably the same preamp with the balanced power supply.  I can't read Chinese so I can't tell if there any other updates.

I consider about M9 and M1 for my M3 and M7 to drive my speaker. The reason i want m9 is about HP output , i also use for my headphone. But i do not know what is the best for speaker and my M3 , my priority is my speaker , not my headphone. Thanks all

I upgraded from Audiolab cdq8200 (cd/dac/preamp) and it was a noticable improvement. It has somewhat high gain for my active ATC speakers but using rothwell atteunators fixed this. Adjusting volume and channels generate clicking noise (per step), but this isn't a problem for me at least.
