I apologize, think I misread your original post. If you were to keep your CD and Speakers, you have a lot of good new stuff to choose from in this price category. For mostly rock listening, I might recommend your $2-3k investment go to something like this:
1. Odyssey Stratos Mono Extreme amplifiers paired with your Adcom preamp
2. New Cambridge Audio Azur 840W amplifier paired with your Adcom preamp
3. Want tubes? PrimaLuna ProLogue Seven Monoblocs matched with your Adcom preamp.
4. Musical Fidelity A5.5 Integrated amplifier
5. NAD M3 Dual Mono integrated amplifier
6. Vincent Audio SV-236 MKII Hybrid Stereo Integrated Amp
7. Plinius 9100 Integrated Amplifier
8. Naim Nait XS Integrated Amplifier - again, lower power compared to these others, but surprising amount of umph and propulsive sound to die for.
Of course, used is an entirely other world. You could look at higher quality integrated or separates from Bryston, CJ, Mark Levinson, Musical Fidelity, Naim, Plinius or many many other choices.
