Here is my humble idea for a keeper amp, ready for this? Ead 8300 amp by Noble electronics. Greg and Tom are two of the best engineers of high end electronics that I have had the opportunity to meet. I have owned a lot of high end amps, My latest were hand built in Denmark, they listed at $24000.00 per pair. I had three pair. Why, my speakers use eight channels of power. I use Magico reference speakers. The sound of the Noble electronic defies all that I have experienced with musicality, air, timbrel accuracy, pace, spacial placement of performers, bass, mid's treble it has it all, and after 35 years of high end as an audiophile, I know a little about this craft. I am in shock and awe of it's performance. Now I wonder about these prices and hype of many high end companies.To Greg and Tom, you deserve a first class salute, for integrity, honesty, and fairness. I have had what some would call it all, this amp takes the top cookie. I must say that I had most of my parts upgraded in my amp, cost a little but is it worth it. Call them and talk to them about getting one for yourself. This is my experience, in my system and to and for my ears. I am not telling anybody to do anything, understand, this is my personal opinion and experience. I am not open to dicussion, just a heads up no rudeness intended. I am sure that Nobles electronics will be glad to answer any questions you may have. Cheer's Ezra
