Probably the first DAC with two AK4497EQ chips.

Fantastic!
The headamp stage is all discretes!

Anyone tried this yet and if the headamp is equivalent to or better than the H-10?

Not quite sure but seems they are using the XMOS U8 chip, I wonder why they didn't go for the XU208 like in the Singxer f-1/SU-1....

Another thread posted on that forum:

Seems to say it's now officially listed and retail price is 4,580 RMB, being about $685. I think this is the listing on TaoBao:

I noticed a headphone socket with balanced output on the front panel. Is it true this DAC-Amp supports balanced head-amp output too?

I think it has dual AK4497EQ dac and balanced amp output.

Any mention of a remote being included with the unit?

genclaymore · Sep 12, 2016 at 11:37 PM

I wonder how it will sound when it is released. I do like it's both SE and balanced.Now I'm interested in an another Gustard unit. But I betting it probably gonna cost quite a lot of money, I hope it won't be too much.

In previous posts, it's ~4,580 RMB, being about $685.

To my understanding, a remote is included with the DAC and you can control the volume (with the built-in arrays of relays!)
