Hi all, I am on the lookout to get my friend an amp to go with his Marantz CD63 and Tannoy M2 Speakers with the above budget. Previously, he had a Marantz PM47. Amp does not need to be more than 50 wpc and he mainly listens to rock n pop. Considering: - Audiolab 8000a - Rega Brio 3 - Arcam Alpha 8, 9, or 10 - Cyrus 7 Any further recommendations or would anyone kindly second any of the above suggestions? Thanks!
