Let me continue in the Official thread
As a pure DAC: + violectric hpa v181 + HD800S (fully balance circuit)
Surprisingly good - wide and deep soundstage, clean, good channel / instrument separation. Taking the price into account - nice deal.
As a DAC/Amp vs xDSD with Etymotic ER4SR - SE output only
ZEN DAC wins having more power on SE to drive ety, sounds slightly more precise, bass response is faster.
But I know that xDSD performs much better in balanced mode (3.5 mm TRRS). Unfortunately, I cannot compare them in balanced mode since I currently do not have any 3.5 mm TRRS cable for the 4SR.
As a DAC/Amp vs Cayin n6ii with Earsonics S-EM6 v2 - balanced outputs 4.4 mm
That was the most interesting part: to me ZEN DAC out of 4.4 mm sounds very close to micro idsd black label with one big exception - noise level.
Zen DAC produces an audible noise with my 6 BA IEM while Cayin n6ii is dead silent.
On the performance side - ZEN DAC performs terrific, as I said - very close to Black Label (or at the level of BL), no questions at all to what it delivers except the noise floor..
For sure, it needs some burn-in time and these impressions are right from the box.
So ifi audio, If this an entry level DAC then I can image how your future Mid and High end DACs can perform.
I can stay with ZEN DAC so far and wait for a higher level DAC from your side. Please do not wait too long with introduction (if any other DACs are planned) since I'm also considering violectric DAC V850 to complete my stationary setup.
