Most likely your current set-up sounds better then the NAD player. I recommend keeping what you have.
CD Player upgrade...?
Currently using a Onkyo 6 disc changer>PS Audio Superlink Generation II DAC. The PS Audio is a 18 bit DAC, I am thinking of upgrading this source to a NAD C541i or 542(or others in the $300.00-$350.00 range). Any experience with these 2 players? If so,will I notice a sonic improvement from my current set up? Thanks..
