I'm looking replace my ageing broken Arcam Alpha plus intergrated amp with something that will give a similar sound. Current set consists of Mission 757 speakers and a Roksan Kandy CD player, I listen mainly to heavy rock,punk, classical and jazz so like tone controls. I do like a lot of ooomph in the bass. I'm considering the Rotel RA 10 and the Marantz PM 6004. Ant other suggestions out there, I have a budget of about £600.
