I had a Krell CD-DSP and got the e20 DAC and used the Krell only as drive. It was a night and day effect...
The e20 was the first external DAC I purchased and I never looked anywhere else. Extensive search before but no actual listening comparisons. At some point in time I accumulated so many hybrid SACD's that I was looking for a player and when a good deal showed up, I picked up the Marantz. I am absolutely happy with the sound either CD or SACD. I was eying some used Esoteric or also EMM but decided for a new unit with warranty rather than something 5 years old or way over budget. So basically I did not compare it at all, I'm just happy how it sounds in my set up.
I visit a lot of live concerts, both Jazz and classic and when I listen at home, it's close enough

+1, same here, new discs piling up, more on the way and the only problem is too little time
