Thanks all-- If I had the space, I would have gone monos for the amp. My dealer just told me MC-452s are all sold out, but they had an MC-462, so that's getting delivered tomorrow. Weird, I had not done anything with my system for close to 20 years but bought a new preamp a couple of weeks ago (Moon 740P) and was amazed at the improvement. The wheels started turning and now when everything arrives, I will have a complete new system ! I'm pretty old and if I last another 20 years, hearing aids will be the next big upgrade
