Used Ayre amp market pricing


I find the Ayre nomenclature confusing in that there are models with the same letters and number but their order seems significant.  I'm looking for a VX-5, not VX-5 Twenty, and wonder what the used market price is likely to be.  A 5-VX is too tall to fit in the space I have with 3" clearance.  Any advice will be appreciated.

How scrupulous are you in observing the recommended 3" clearance above the amp?  I can see maybe less than 2" being available, so I wondered about installing one or two 6" exhaust fans in the side of the cabinet adjacent to the amp.  The front and rear of the cabinet are open.

The cabinet will house a Sony HAP-Z1ES, Oppo BDP 105, Ayre K-5xeMP and V-5ex.  Another possibility is to mount the Ayre units on the upper shelves and mount the exhaust fan in the top of the cabinet, although that would be cosmetically more intrusive.  The cabinet is glossy black.

The one good thing about the VX-5 is that it can upgraded to a VX-5 twenty later on at a reasonable price.
I installed a K-5xeMP preamp yesterday that replaced a Cary Cinema 12 processor.  I'm using a 30-year-old Proceed Amp 2 to drive a pair of KEF LS50s.  Sources are an Oppo 105 and Sony HAP-Z1ES.  All connections are balanced.  The sound quality is excellent, with sufficient LF extension that I don't miss the subs.  The Ayre preamp is a big improvement over the Cary processor.  I'll continue to look for a VX-5 not V-5xe, but the dual monoblock Amp 2 is serving well so I'm in no hurry.  The setup appears clutter-free, with everything fitting in the cabinet and without the subs and bass manager.  I suspect replacing the Amp 2 with a VX-5 will not have the impact replacing the Cary C12 with the Ayre K-5 had.

Btw, it seems like a bit of over kill to power up a pair of KEF LS50s.  Hee hee...You might want to starting look for a used pair of Vandies to advantage of all that Ayre gear you're collecting :).      
You'd be surprised how good the LS50s sound in the setup.  I have a setup that uses KEF Reference 107/2s and 204/2C driven by 3 Parasound JC 1s.  The stereo preamp in that setup is a JC 2 BP, surround processor a Bryston SP-3.  Sources are vinyl through a JC 3, Ayre C-5xeMP, Oppo 105D, and Esoteric SA-60 disc players.  The setup use a pair of 15" subs for surround and HT, but not for stereo.
