I wouldn't read too much into the statement that the K-01 soundstage was "flat" or "collapsed" in comparison to the Lampi. The Esoteric will sound different based on what input was used, what cables were used, what filters were used, etc. Was the system optimized for the Lampi? What part did the rest of the system(s) play in this? We've all heard tube bloom, it's real and can have an effect on apparent soundstage and depth. I will say that the Esoteric, when set up correctly, throws an immense soundstage with tremendous depth. I will also say that the rest of the system should be optimized for this to occur correctly. It is just as valid and possible that in an appropriate system, the Lampi may not sound nearly as good as the Esoteric.
Hi Steve,
I run the Esoteric K-01 DAC at +6dB output on the asychronous USB setting with a WW Platinum 7 USB cable. The rest of the system is a Soulution 520 Pre, 501 mono amps and Raidho D3's. I'm getting world class sound quality in my opinion and the soundstage is huge. The K-01 holds up its end and then some in my system. I've heard few digital front ends that can match it.
Best,
Ken
