I'm looking at downsizing my system, want to try something different. Currently I use an Ayre KX-R preamp and two MX-R monoblocks, with Proac Response D80 speakers. Sounds great. The dealer wants me to listen to the Rowland Continuum 500. To those of you who bought a 500 a few years ago, I'd be interested to know if you still have it, has it changed with time, and are you still happy with your purchase. Or, have you moved on to greener pastures?
