@buellrider97, thanks for sharing your experience. I might try reinstalling my new tubes and see what happens. When I first got the Linlai tubes, I was inserting them into a pair of tube socket savers. I did that because I was thinking about doing some A/B testing with the stock EH tubes. After deciding that the Linlai do sound better, I removed the socket savers and inserted the Linlai directly into the sockets of my preamp. I cannot remember when the very first time I heard the pop, whether the socket savers were already removed. The latest pop I heard was this morning, and I know for sure the socket savers were no longer there.
@immatthewj, yes I did buy the NOS RCA tubes from Brent and I do like them better than the stock EH tubes. The EH tubes sounded a little too bright for me at the gain stage. The RCA took the edge off and sounded warmer. As with the Linlai, I do like them quite a bit. I was going to post an update to the long going Linlai thread, but haven’t gotten around to it. The Linlai has tighter bass and better sound stage than the stock EH tubes.
As with the Cary, I actually had another issue a couple of months ago. I was so pissed off that I was going to start another thread venting my anger, but I decided not to. I did mention it in an old thread because someone posted a question. Lucky it was a fairly minor issue and I was able to resolve it without having to ship the unit back to Cary.
@curiousjim, I do have a power conditioner. I was most likely streaming from Tidal when I heard the loud pop. Thanks for sharing your experience with Amazon. It does seem kind of weird.
