No loaner, no explaination without asking James directly via email and no sorry you haven't had a processor for over a month.
When I first purchased my SP1.7 I got a fautly one and it took nearly a month to replace that.
So my SP1.7 experiences haven't been good.
No problems with the 4B SST, 6B SST or 7B SST amps but I won't be upgrading the SP1.7 or purchasing Bryston processors in future.
I have to point out that PMC aren't to blame in these issues. They have always kept me informed.
