Bought the DA02
Have let it run 7 days after first hour of listning.
I found the tube output nicest sound (less accurate 0.1 % distortion)
On SS output hmmm typical opamp sounding oke more detail but less musical.
Headphone is very poor quality, loads of white noise, i think a cheap opamp. (i don`t use it)
Very good dac for its money, i did listen to dac`s from 300 euro till 1000 euro, this dac does get close to 500 euro types.
I use the dac mostly for my teac vrds 10se as cd drive, with tentlabs clock
On BNC it preform outstanding much better then coax rca or usb, usb is nice for background music from labtop to dac.
Now 2nd week i already took out the WIMA caps (horrible mpk`s, nice for in the 80ties) changed them to audyncap plus, woow far more detail.
Next week i drop all the 3 opamps out, change those to burson discrete opamps.
Rectifiers are also exchanged by Schottky
diodes 30nSec fast recovery
Now it is burning in will drop a line of comment after next week
Just bought second hand the burson opamps for exchange the 3x OPA6204ap (halfpriced)

This is a two layered opamp, expensive? yes it is but it overrules every opamp i ever listen to
Interested?
