There's no switch to invert on the CA50. Nothing on the latest ARC integrated...the VSi60.

On a somewhat different topic...How much is the transport going to matter in this arrangement? If I move up with the DAC, is there any harm in sticking with the same CD player? Or for that matter, my 20-year-old Pioneer PD-7050 is still a competent machine with an interface and remote that I really like...or is that getting a little carried away?
