Next Purchase to Upgrade?

Old Phase Linear 400 powering Magnapan 1.5QR with Rel Storm II sub. SAE Mark IX B preamp and Marantz 65se cd player. Would like to start system rebuild with oldest units back. Was considering an integrated amp and cd upgrade as possible starting point. Any suggestions on what to listen to that would be compatable with current speaker set up?

If it must be solid state - please audition the Pass Labs (Aleph 3 or 30) and the McCormack DNA (0.5, Deluxe 1, or 125).

CD Player? Arcam CD73 is a wonderful entry level player that will ....not may....but will embarass players up to $1500.
