This is my first post here. I've been lurking for a week or two now, and thoroughly enjoying everything I am reading and the wealth of information and opinions here.
Yesterday I got a Bifrost + Lyr combo to drive my T1s. I'm exceptionally happy with them, but I noticed that the Lyr makes an odd noise every so often. It's like a soft, metallic "ting" or "clink" audible only through the headphones. It's definitely not related to the Bifrost muting relay. It happens even with the Bifrost off/disconnected. It is neither loud nor particularly awful, and is very sporadic. Is this typical for tube amps? Is it the tubes warming up?
I'm also getting right channel crackling/dropping out occasionally - however I suspect this is unrelated and I've ordered new RCA interconnects as that might be the problem.
Any thoughts on the noise?
