PS Audio vs. Cary

I'm on the verge of purchasing my first audio system and need a little feedback. I've recently purchased a set of JmLab Chorus speakers (which I'm sure I will upgrade in the near future) and wanted some advice for amp/pre/cd.

I've pretty much decided on used equipment with the top two being PS Audio(HCA2/PCA2)and Cary(CAD308SA/SLP308), with Bryston and Proceed products on the outside looking in.

I'd like any opinons regarding any of the 4 listed above.

Thanks in advance,
Scott
