Amp Suggestions For A Newbie - Please


I am upgrading my system. New to components. Live in an apartment house. Listening space is relatively small. Considering either B&W 602s or Paradigm V20s. Very much into jazz and classical (acoustic). Wish to achieve good clarity, distinction and presence with my new system. A depth to the music. Looking for the strongest amp candidates for the abovementioned speakers. Obviously lots of power is not a requirement just quality and character of sound. Either New or Used Amp suggestions are fine. Budget: $500/$600. (If you feel I would get equivalent results from an integrated Amp, let me know that, too. Appreciate both your time, input and thoughts.

I can't help much with your speaker selection, but can personally recommend the AudioSource Amp 1/A (80 watts/channel and an excellent performer) as well as the AudioSource Pre 1A preamp highly. Both the amp and preamp can be purchased new for around $500 - $550 total. They are solid entry level pieces, and the amp is stable into even 2 ohm loads.

If you feel you want even more power, the AudioSource Amp 3 (150 watts/channel at about $550 - $575) might be a good choice. See the following link for pricing, additional info, and a dealer who sells these units:

Happy Listening!
Had the 602's with a Musical Fidelity A3 and the combo was quite good! The 602's are quite good for the price and the tweeter is very resolving. Audition as many speakers as you can and go from there.
Fullrun,
In your price range a used Audio Refinement Complete is very nice. The price maybe to high but a used Audio Analogue Puccini is also sweet. NAD is also decent but tends to be a little forward to my ears. If you do not want used you may also want to audition a Jolida tubed or hybrid integrated.
Cambridge Audio from England makes a great integrated amp A500 which carries a Stereophile Class C rating. It retails for $450. You can pick up a dempo from Audio Advisor for $339
