Hi, Moving your amp from the pre-amp helps move the large power supplies and equipment from the pre-amp where distortion can be picked up. This is one of the reasons for sep components and why some pre-amp power supplies are external.
I use 4M Harmoinc Tech Pro Silway II XLR interconnects between the 334 and 380. I have also used Audioquest Diamond X3, but the Harmonic Tech interconnects are more detail. Between the 380 and 39 I use 1M Harmonic Tech Magic One XLR. I also vaious power cords, such as, an Electraglide Fatman K2 on the 334 with a PS audio ultimate outlet.
The Sony is a good plyer for SACD, but on normal CD's is not as good as many other plyers. It may be limiting when you upgrade.
