Hello everyone,i would like some help with an upgrade puzzle. I have recently bought a n arcam 73 after my old Nad popped its cloggs.I was very impressed with the soundstage and speed ,and fed through a marantz 6010 and B&W 601s my music sounds real and exciting.However ,i can get a boomy bass and a harsh treble sometimes which is distracting and annoying after a while.To get the speakers moving you have to turn the volume past the quarter to position so i thought a more powerful amp might be the answer .I auditioned the arcam a80 and found it to relaxed and then the salesman played me a cyrus 6ve which was a toe tapper but still didnt have the excitement.Perhaps it was the MA 8 speakers they didnt have the dynanics ,but i just wasnt convinced.Any suggestions of what i might try would be appreciated.I have a small listening room by the way.
