I currently have a Supernait 3 on loan from my dealer to assess before making a decision on whether to buy or not. In the three weeks I’ve had it it’s been fine and I’m loving the sound in two channel stereo for music playback.
But at 5am this morning I was awoken by a loud noise downstairs. On entering the lounge there was extremely loud feedback coming from left/right speakers. I immediately switched off the Naim amp and went back to bed. I’m sure it woke my neighbours it was that loud.
At 8.30 I switched my system on again. The same feedback noise started again. Turned Naim off a second time.
The input on the Naim was set to AV and the bypass switch was ON. My Yamaha Aventage RX-A3010 AVR was connected to the Naim via two RCA cables from pre-out into the AV inputs. B&W loudspeakers for left and right channels were connected to the Naim. The only input to the Yamaha is the SkyQ box via an audio digital cable.
I spoke to the dealer and he suggested powering the Yamaha off for several minutes to allow it to reset. I did that and during this time the Naim was also powered off.
When I turned the Yamaha and Naim back on everything was fine. No horrendous feedback noise. I have a SkyQ box connected to my Yamaha and although the AVR was in standby mode it was last set to the Sky input.
Is this just a one in a million incident or should I be concerned about any incompatibility between Yamaha and Naim? For three weeks everything was fine. Maybe it was just a power ‘blip’. Hard to say. But before I commit to a purchase I need to be reasonably certain this won’t occur again. In 40 years of owning hi-fi I’ve never had this problem but this is my first amp with HT bypass.
I’d appreciate any comments or advice from Naim as I have a decision to make early next week.
