Parasound is a tough call, they make a broader product line than some other vendors, their Halo amps get good reviews, but they ain't cheap. Similar things can be said about Adcom, their sound quality rating seems to vary from model to model and occasionally from year to year.

The reviewers do usually praise Anthem, but as far as I know most of the Anthem line is on the lower power side of what you indicated you wanted. Perhaps I'm not up to date here.

Several things about Bryston; that 20 year transferrable warranty, long history of good reviews, pretty much bullet proof (since they are a very popular "pro" amplifier), high availablity used and a very nice (prompt and reasonable cost) company to work with for repair or upgrades.

Gear I have owned that I can recommend as "non fatiguing" is Conrad Johson, Levinson and Pass Labs, my friend owns Bryston (Ditto on non-fatiguing). I never liked my Denon stuff, but not everyone agrees. Most vacuum tube gear is suposed to be quite good, but at your power level mostly out of financial reach. Not everyone enjoys tubes hassle, some delight in it.

eCoustic.com has the most extensive list of magazine reviews I've seen.

You are talking about spending what for most folks is real money, some effort is indicated. If you live in a big city, you can often find used gear within driving distance, go listen.
