For anyone that places any value on my knowledge, if you need a complete system for around the $2000 range, you can do much better than is typically recommended. What I recommend below will approximately equal(in terms of actual measured performance) the better 'audiophile' gear that would typically cost about $15000-$18000 new. This is due to 1. The severe used depreciated in price(but offer superb performance, even compared to top quality modern speakers) speakers I am recommending 2. using good quality low price amplifier, preamp and CD player in place of the typically over-priced ones used in such price range systems that do little more than provide prestige.
-B&W 801 Matrix Series II or III off of eBay($1500-$2000)
-Adcom GFA555 amplifier( 235 watts x 2 @ 8 ohms, typical measured) off of eBay ($300-$375) or similar power/value amplifier at this price range.
-Adcom 350 preamp/tuner or similar ($100-$150) or similar quality/value.
-Any used good quality CD player ($80-$150)
If you wait it out and get the lower winning bids for each item, you can stay very close to the $2000 limit, minus shipping. However, please consider room treatments as non optional, and consider them an additional cost. Just throwing this stuff in a random room(no matter how good the stuff is) is not likely to approach the potential possible sound quality.
