Report "I have a set of Nad C275bee and when they go through the power up sequence, on the first click all is well with both amps but on the second click there is also a "tock sound" that comes out of the speaker it is hook up to, and dead silence in the other speaker, apart from this at cold start up they work fine after that, but at warm or hot start up the second click comes quicker on the same amp. At shut down it also get the same " tock sound" out of the same spasker, Thanks for your assistance!"
