Cello "Suite" or "Platte" are the two most greatest amp ever built on earth. When we judge an equipment whether it is the best overall, we always look for how long it could last. By all means, the one who could survive on the market for a long time should have its own value. For some example, Cello "Suite" or "Platte", Jadis "JP80MC with "JA500", Matisse "Reference" pre-amp and power amp, they are the best whcih I have ever heard in life. You can tell how Krell and Levinson changed their models that often. But, do Porsche or Ferrari changed their model a lot?
