Does the Transport make a significant difference

Jfrech,
So true!
And everyone has their own opinion as to what to do.
Ricred1, looking at your set up I would probably consider a higher end CDP and/or a transport.
I would select the CDP or dedicated transport at this time over a preamp.
There are so many very good brands out there I hate to make a suggestion.

I've owned a number of different CEC Transports and a CDP over the years (although I don't currently own one) and I have always found a special sound do to the belt drive system.
Enjoy...
