Ayre KV-5 Twenty or Parasound JC 1
I think you have your answer.  :) 
Ayre KV-5 Twenty or Parasound JC 1
Are the JC1's brand new?  They do take quite a while to break-in so even if you were to try them they won't be at their best for several weeks from my experience.  So even if you were to take the effort to set them up you won't get the true flavor... 
Sold My Ayre QB-9 DSD - Help Me Choose A New DAC!
I'm in a similar position as the OP and still have my QB9 DSD.  I'm very seriously considering the Twenty upgrade as I am still impressed with it and have a hard time justifying replacing it without seeing what the Ayre guys were able to do. 
Ayre KV-5 Twenty or Parasound JC 1
There's only one way to find out!  You're in an enviable position having all of the equipment on hand.  I'd try both setups out to see which you prefer, both are excellent.I have had JC1's for many years with no urge to change, and also use an Ayr... 
old high end preamps..
Exactly right twoleftears. The Denis Had equipment is outstanding. Once he left it became all about profit margins IMO.gentle jax, if you are happy then that is all that matters. I don’t think I am "hating" on Cary, I’m just disappointed in the ne... 
Revel Salon2 with Linn Klimax Solo Dynamik
I'm a former Linn owner and tried some of their amplifiers with non-Linn speakers and in my experience they were a let down.  The Revels like lots of power and I think you could do much better than the Linn amps.Just my experience. 
Most enduring audio purchase
I'll second Aerial 10T's, closely followed by my Parasound JC1's. 
old high end preamps..
The 98 is a great preamp, and I imagine it's still the same design as it was.  I owned it for several years and would easily recommend it.  It's one of the old point to point hand wired designs and really is a fantastic preamp. 
old high end preamps..
@skiroe You can look at the images on their website.  Some products say "Made in USA" while others say "Assembled in USA" on the back panel.  The old Dennis Had products, which IMO put Cary on the map - are the ones made in the USA.  These include... 
old high end preamps..
Of the three listed, I would choose the Proceed but wow it's really old at this point.  The offshore Cary stuff never impressed me and I've never been a Bryston fan either.Good luck with your decision! 
Smart Hub Recommendations
I've been using SmartThings for a couple of years now and am very happy with it. 
Classe CAM 350 monoblock vs Classe CAM-400 or Bryston 4B3
I compared the CAM-400's to the Parasound JC-1's and the Parasound was a clear winner to my ears.  I still own them after many years while nearly all of the surrounding components have changed.Today I wouldn't consider the older Classe equipment j... 
Extra power or cleaner power?
Better power always IMO. 
New Parasound Halo JC1+ monoblocks just released!!!
Very happy to see an updated JC1, however I am in no rush to replace my originals. 
BAT VK 53SE vs ARC Ref 5SE
Agree with @zkidd .  The 6H30 is a tube that sounds like a transistor to my ear.  I think it's for those who want transistor like attributes but still like saying they are a "tube person".
