For what it's worth, a DR-9 can't be beat for price and built. Many other ss amps I have heard including Krells might have more bass, but they never capture the soul of a recording as well as a Classe DR-series amp.
Im in a similar situation as yourself and have been wondering about this for awhile. I also have heard great things about the portal panache integrated amp. I wonder how that would stack up to the krell and classe.
