Justhavingfun,
Thanks! I will do so. The Adcom 7500 is a solid Amp made in the USA, but the Adcom Preamp I bought at the same time was made in China, that disappointed me a bit and it did not last as I expected. Anyway like my last mail said upgrading to 7.1 will not give me a clear improvement in my listening area now. I will wait a while.
