I currently have the Arcam Alpha 9 integrated amp and i'm going to audition the B&W 685, 684 and Monitor Audio RS6 and RS8 speakers tomorrow to initially go with my Arcam Alpha 9 integrated amp. What i would like to know are peoples opinions on: I am getting my other Arcam Alpha 9 integrated amp and Alpha 9 Power amp serviced by Arcam next week so should i keep them to go with the speakers of my choice OR Should i go for a brand new NAD C352 or C370 amp? My only reason for asking is that the Arcam's are 9 years old now and even though they still sound brilliant to me, is it time to replace?
