I don't know about the amps, but the EAD TheaterMaster Signature sounded way better than the Proceed AVP in my system (B&W Matrix 801 S3, Krell KAV 500). The EAD had a more transparent, airy, dynamic, and musical sound with a slightly recessed presentation relative to the AVP.
If the amps are of the same sonic family I'd definitely pick the EAD!
