My last Integrated Amp: $5-10,000?

Gryphon Diablo 300 if it's going to be your last integrated amp. I currently have one and it's a superb amp - will drive any speaker. The one on USAM will go soon if you don't jump on it.

I’d put more emphasis on reviews/reviewers who take the time and effort to compare a review sample to another competitive piece, otherwise the reviewer could just be listening to the reviewed product in a bubble and relying on longer-term auditory memory — that is horribly unreliable — to form their opinions and judgements. Read pretty much any TAS review and you’ll see they don’t compare review equipment to anything else and usually just gush over what a product does well as throw in a lightly-worded sentence or two of where it falls short.  And in many of their reviews they don’t even disclose any of the associated equipment currently in their system, and if they do they conveniently omit only the piece in the category of the review sample — WHAT??? Bunch of cowards desperately trying to avoid accountability or being pinned down on anything.  Worst of all, after I read one of their reviews I can’t say with any confidence I have a good idea of how the product really sounds. Stereophile, Soundstage!, and some others usually include product comparisons as a matter of course (I know Soundstage! requires relevant comparisons to be part of every review and for good reason) so they’d be worth seeking out more than others. Just my $0.02 FWIW, and best of luck in your search.

you have to give the Cary AUDIO sl1-100 a shot. Have mine for a few months and you will get excellent sound

There are lots of great amps on the market. Review that are positive are good… but after that it is the character they talk about… detailed, fleshed out… The Absolute Sound, Strereophile and HiFi+ are really good a about describing the sound in generally accepted terminology that characterizes it… so you can figure out if it fits your preference. The trick is auditioning equipment they review… if you are calibrated  to the nomenclature… then you know what equipment you will like. 
 

I would buy an Audio Research VSI75 long before I would consider many others. The reviews and listening have shown me this brand shares my values in sound.

Pass, Rogue, Audio Research, McIntosh, Boulder are all very different. You need to find the company that speakers to your emotional center. Worth some auditioning.

Sorry if I missed it…. Is this new only?
