I first got the Chord DAC64 and am using a Rega Planet 2000 as a transport. For amplification, I am using Conrad Johnson's CAV-50 integrated amp which drives a set of Totem Signature Model 1.
Adding the Chord added a whole new dimension to the music! As some reviews say, it is if I just got a new cd collection. It is amazing the improvement it gave.
I just added a CEC TL1, and I must say that the sound improvement was a bigger jump than adding the Chord. The soundstage is fuller, voices are more transparent, the highs are just so lucious, and the bass is fatter and controlled.
The music just flows much better. There seems to be a "wetness" to the sound. Just amazing combination i.e. TL1+DAC64!
