Sonic differences ?? NAD 317,370,372 integrateds

Has anyone owned or compared all three of these NAD integrateds? NAD 317 370 or 372. I would be using it with a Rega Apollo, Analysis Plus Oval 9, Analysis Plus new copper oval or Cardas Neutral Reference and Polk SDA1Cs. Thanks,keith
I haven't heard the 317. The 372 is a good bit better than the 370 to my ears. More refined and controlled, across the entire audio spectrum.

To be honest, I liked the 352 the best of all NAD integrateds. Something about it that I can't describe.

The Apollo is a great CDP. The Rega Brio can be found for good prices used. Have you considered one?
