If you are into used, I would recommend McIntosh amps (here or ebay) if you can find one in good shape.
Denon 3800 DVD offers good sound as well ($450 ecost.com) refurb.
Speakers are difficult to suggest - I would listen to your type of music on big names like Paradigm, PSB, Mission, Monitor audio, etc and go with the one you fall in love with. Try to find one with good tranparent tweeter.
