Impressions: used first the coax-input (Samsung BD-Player) ->absolutely massive !!, thought: more hi-fi again (as with the first ES9018K2M+ES9028Q2M, not soo with „Blue“ ES9038Q2M..)
interesting is that the NE5532 is absolutely great on this „Green“ one; fabulous sound via spdif/coax+NE5532; goes really down and with good „push“..
changed first to the Muses8920 and then to 2*AD797; stick now with the ADs->more „room“, better THD, almost too thin for some i would say (in opposite in using them on the „Blue“ ones..).
would say a better performance (Green vs. Blue) by 5-10% 😉 (its also ca. 20% heavier („Green“) and the PCB is thicker; got the feel has a better „ground“, especially for the „lows“)..
other differences: the „Lock“-light on the „Green“ is more „torquise“ and is only lit in playing something over I2S (over coax its permanently)..“Blue“ Lock-light is red and permanently lit (at connect).
(if u have other questions, please leave a comment here->Link above)
many greets for now 😉
