In my humble opinion this is all very system dependent. I have used it with my CEC TL-1X for a number of years with the right power cord on the CEC and Esoteric/Acrolink and the sound is heavenly by analog standards. I know the sound of live music and the CJ captures this much better than many of the audiophile stuff out there. Modifications can begin to reveal shortcomings in the rest of one's system. I have ribbon drivers and also electrostats which are verty transparent.
Listen to it in stock form with the right stuff and it is magical indeed. However you will be surprised that it is not the DAC that can be the problem but the transport. The differences in transports have been amazing to say the least. I found most of the ones I used were very mechanical: Sony SCD-1, Marantz SA-7, etc.. Only the CEC was up the standards I am looking for.
