I agree with all of what is posted above but there is really no best CDP. They all have a different sound and you have to hear each in your system to see what works for you. I know it is hard to do, but that is the only way I could tell what was best to me. I recently did a DAC comparison and had the Audiomeca Mephisto II.X used as a CDP and as a transport with the DACs along with a very higly modded Shanling and stock Sony SCD-777ES. I prefered some of the DACs sound to every CDP we threw into the mix. The Electrocompaniet threw the widest soundstage and is very detailed, the Ameca is more lush/warm sounding but no like a tube unit, the modded Shanling bettered them all but again it was a special highly modded version that you cannot find on Agon. The Audio Logic DAC was clear and sweet and the Chord 64 DAC was excellent also. But again each has pluses and minuses that you have to hear in your system to understand. All of the above suggestions are excellent.
Happy Listening.
