Don't discount the Sim evolution products lightly. I have the W8 Amp and would not trade it for anything under 20K. The integrates are obviously of the same technology. Best to find a dealer and listen to it instead of listening to opinions here. Sims have a very good pedigree and zero feedback design aswell. The people making these products are fanatic about audio...beleive me, I have met and spoken to a few of them at the Montreal show.
cheers and good listening
