I currently have a Rotel RC-995 preamp powered by a Rotel RB-990BX Amplifier and I am thinking of upgrading the amplifier to something better. My choices right now are the following: A Aragon 8008MKII or a Bryston 4BSST, I cannot audition either of these amplifiers even though I can get them for a killer price. I have forever been trying to read through reviews but I haven't been able to find anything that points to one over the other. Except for the fact that Lexicon uses Bryston technology, and the Brystons have a 20 year warranty as well as a extremly low THD of <.007%. They will be driving two Axiom M80Ti towers in a stereo system. Let me know what you guys think.
