I have the MX-R with Wilson Sasha. I listened to the Naim Supernait with the Sasha and I was impressed. I don't know how this would match up with the speakers you are describing but if you like the MX-R sound you may like the Naim.
Downsizing from Ayre MX-R monoblocks
I am looking to downsize from my previous amps, the wonderful Ayre MX-R monoblocks to an integrated amp. I want something that has the same quality and sound as the Ayre. I know the Ax-7e is an option but to be totally honest, I am not too keen on its looks. In terms of price, I would like to stay at $5K or less used. Any advice would be greatly appreciated.
