Hey!
Well, I don't have lots of exprience with transport.
But I've been using Sony CD/SACD 5 disc changer as my transport for a while now

Yes, I know it is not really an audiophile thing but I'm pretty happy with it

Kindna nice when I could just put 5 CDs that I want to listen that evening and let it spin.
I've tried using my computer as server but somehow I still like to use my Sony changer. Maybe I will need a better digital output device or something.

Take care,
Buddy
