Does anyone out there NOT hear a difference in CD

Considering the equipment that you currently own, you should be able to hear differences between the Cambridge and the Pioneer. You mentioned that a clear improvement is needed if the switch is to be warranted. Whether that happens depends on your tastes and system synergy. Keep your expectations reasonable; to a certain degree you are taking a step sideways.

Keep the PD-65 and add a DAC. The Pioneer has a better transport than anything you can buy new near the price.

Gentlemen:
What does it cost to mod a PD-65? What does it cost to get a D/A that sounds as good as a OPPO stock after break-in ? This is just one example. This particular advise I take umbrage with . What will be the resale of the modded PD-65/,d/a ? Apparently there are Goner's that have the time and money today to waste on these type of expensive experiments, as they repeat themselves one after the next. Once again, in today's ever diminishing value of our spending dollars, I believe advise should be well thought out, and prudent.

Jerrym303's idea might be the way to go,would you hear a difference for the better with the Cam. probably yes,just depends if you want to spend the money,But the thing is with dig,once you even have a decent player the differences dont stand out nearly as much as compared to when you get a different amp or preamp.

Fruff: If you can't hear any difference, don't change anything. Save your money. But I will tell you this.
I had the Pioneer feeding an Adcom 600DAC for about 10yrs.
And yes, the combo was fantastic back in '96 or '97.
But I have upgraded the transport twice since then.
Now, I just have a $400 oppo with no external DAC.
That's right, I tried the oppo with the ADCOM DAC
and didn't like it, which really threw me.
So there you have it. I hope this helps
