Sounds better than similar devices for this amount. Wish the manufacturer to move on and release a second version of this heron with a shorter signal path.
Amazing performance and value.
Sounds good, for its price just fine (16800 p). Sorry there is no remote control for adjusting the volume, K11 as before me now, immediately goes to the Powerman. And it is better to feed it immediately from the Lbp. Set the Nos mode and connected the Coke with the source while I listen so.
Hype cap. Works. How well-it will be clear later. The packaging is normal. Delivery in 21 days. But this is not the seller's problem. Five days the package traveled from Samara to Togliatti... (90 km. ..)
Nice R2R Dac, Running on Hifiman edition xs and at 50% power is more than enough in balanced output, single ended output is awful so always use the 4.4 balanced output

Sounds great considering the size and price.
I recommend it
It's only now that I have an emotional appreciation of music.
Output from dm13 to light to K11 R2R
You can connect it and enjoy it with a vacuum tube amplifier.
It's comfortable and nice.
