Rudi do not like and never sell any amp coming from any customers (returns) as new, this is why sometimes you will see a few demos going around on eBay (but not very often, as just a minimal numbers of customers returned his amps to him, or upgrade them for the next model)
Having owned several mono block designed amps and dual mono preamps by Krell and a bemoth 200watt custom designed tube amp by Tim Parvicini, I can tell you that a dual/ mono version is always superior- tighter and extended bass, more open midrange, sweeter extended highs with air, better soundstaging with each instrument defined in its space- I could go on and on. I believe it's got something to do with the laws of Physics-you just get more current (clean power/energy) which enables it to drive the speakers/headphones better.
Look forward to hearing these favourable impressions from you guys at the Jan 30th meet.
