I had a similar problem to this with a tube buffer in my system a little while back, which I eventually discovered was interference from a wi-fi booster (one of those TP Link boosters that uses the electrical mains cables to transmit the wi-fi signal).Have anyone had any problem with popping/cracking in the right channel or left channel without anything connected to the amp just headphones? I've got this problem with Elise, right channel has random popping/cracking noise if I switch valves it has the same problem in the right channel
No dac, no preamp, nothing connected at all
Could be that or other interference.
But being in only one channel, I fear it could be a fault with Elise.
Is it not still under warranty?
