I can tell you this; the gen 5a will be holding you back. It's dated. Your transport is fine.
Need some Suggestions on Best Digital Cable
I currently own a CEC Tl-1X and a Theta Digital Pro-Gen Va D/A converter and would like some suggestions on some ''high-end'' digital cables. Preferences would be cables that are detailed but warm and have a nice rich overall smooth sound. The rest of the system is ''older'' Rowland Electronics and Avalon Speakers.
