I was looking for some advice from you knowledgeable people on a problem I'm facing with my second system.....at the minute I have these components: Linn Ninkas Nad 314 Amp Panasonic Viera Plasma TX-P46G20B Linn K400 speaker cable (bi wired) I'm streaming from Spotify through the TV, and also using the set up as improved sound for the TV itself. Over the last year, both of the speakers have been cutting out at various points....sometimes the sound goes really low in one speaker, sometimes it drops in and out, and sometimes it stops completely. Both speakers are doing the same thing (at different times). I'm presuming it is a problem with the amplifier inputs? I've had the NAD for something like 15 years, and it may be time for a change.....but I know the Ninkas are 4 ohms? Does anyone have any advice on which amps I should consider? Or what the problem may be with the speakers (any other Ninka owners here experience the same thing?). I'll be buying second hand.
