I cannot get any volume at all out of the left speaker channel on my Naim XS integrated amp. I switch the speaker cables and find that both speakers work when connected to the right speaker channel but none work when connected to the left. I have tried to balance the speakers using the balance controls on the Namcor 4 remote but with no success.
I can’t remember exactly, but I think it was under £200, any a few other bits were updated at the same time. It took about 3 weeks till I got it back, but some of that may hav3 been due to timescales for when I was able to pick it up from Audio T.
You could also try asking Class A in Sheffield. They are a Naim authorised service agent, and possibly quicker and cheaper than getting your dealer to send the amp to Naim.
