I like the Onkyo A-9555. You can get it new w/warranty from Amazon for around $474, or B-stock from
http://www.accessories4less.com for $400.
I like it better than the Rega Brio, the Cambridge 540 and 640, I like it at least as well as a 3x as expensive Musical Fidelity or Creek. The Outlaw RR2150 doesn't deserve to be mentioned in the same sentence. It puts out a healthy 85/170 wpc into 8/4 ohms. It is shockingly quiet, especially at its price, and can output instantaneous peaks up to 80 amps, making it sound like a bigger amp than it is. Its way with low level details has been described as tubelike by the big audio mags, and it has a smooth treble and transparent midrange. It has far more balls, clarity, and extension than you'll get in this price range from the sub-$1K Brit integrateds and it will definitely show your B&Ws who's boss.
I have been living with mine for 3 months and like it better than ever. Put a good power cord with it and give it 100 hrs to break in. With Amazon's 30-day home trial period you absolutely can't lose.
