Let me preface this by saying that my 2 channel system before the addition of the Ultra DAC consisted of: Conrad Johnson PV14L tube preamp, Consonance CD120 player, Van Alstine OmegaStar 440EX amp, & AAD 2001 monitors. The musicality of the system was superb to put it mildly. I was extremely satisfied, "BUT". Here we go, you know what that means. The never ending quest, the relentless need to squeeze that something extra out of my system. Already being amazed at the performance of Frank's amp, I just had to try his Ultra DAC. So order it I did. The wait is finally over & here it is on my door step. I get it all hooked up & load my first CD. Bam!! what happened to the broken glass??? No, not to worry, nothing broke. What's missing is something that I never realized was there in the first place. That nasty digital edge that is the devil as far as recorded CD's are concerned. Something I suspect is there on a lot of CD players regardless of price. Some more than others. The Ultra DAC totally eliminated it. In trying to get as close as possible to analog sound from a digital CD, the Ultra DAC is a marvel. What comes to mind is absence of fatigue, with no digital glass breaking, the music is just so much smoother. I also noticed a better separation, depth, & amazing dynamics. The voices are so crisp & addicting. Now don't forget, the CD120 as a stand alone player is a stellar performer, but with the addition of the Ultra DAC it's now a world class performer. Extremely pleased & highly recommended!!! Good job Frank, (kudo's to your DAC gal) who is she?
