Dear Cosmin,
There was an unfortunate typo in my previous post, i.e. I wrote "statements" (plural) instead of "statement" {singular}. I was disagreeing with you saying that E-560 is practically a different new amp. Indeed, Accuphase advertises the E-560 as being a model change from E-550 but this is not really the case.
I am not sure I understand what you mean when you say the E-560 is a blend of E-550 and E-560. Did you meant to write a blend of E-550 and E-450? If yes, then I should say that E-450 is not faster than E-550. Definitively not when listening to acoustic guitars or harps. Because they are much more powerful, the E-450 and E-460 models delivers bass drums with much larger impacts/attacks than the E-550 and E-560 models. This is not just my opinion, read for example the review of the E-560 on the Accuphase site.
I will stop now as I really do not want to get into a debate with you, especially since it seems we both are (impreuna cu Puitu62) very found of Accuphase and obviously like very much the Accuphase house sound.
What speaker are you using with your E-560 Cosmin? Also, did you by any chance compared the E-560 with Accuphase pre-power combos, e.g. the A-45 + C-2410?
I am looking forward to you answer Cosmin.
Best wishes,
Paul
