Best Amp for Parasound JC2

Hi,

In my other thread I asked about the JC2 vs Aesthetix Calypso vs Ayre K-5xe. I intend to get the Vandersteen 2CE Signature II or the Harbeth 7 SE. I also auditioned the Totem Mani 2 Sig. which has a remarkable bass.

Now that I've settled on the Parasound JC2, I'm seeking the best used amp ($2-3K)range to match the JC2. Parasound JC1 monoblock is an obvious option but they're on the expensive side and too big in size (one for each channel) and I don't need that much power to drive the speakers.

How about the Ayre V-5xe stereo amp? It has the same inupt impedence (100 Kohm) as the JC1.

Anyone used the Pass Lab X or XA 30.5 with JC2? The input impedence is not matched on paper. Any other recommendations? Tube amp?

Thanks.
