Mr. Bob carver made some okay stuff and made some decent audio equipment. I remember the little m-400 power amp. Very clean and efficient that little square box push my jbl 4345 Very nicely. I sold it some years later but wish I kept it. Never own any carver tubes equipment but I damn sure heard them performed. Very sweet and musical. I’ve own stuff from fisher tube equipment parasound audio research mcintosh threshold nakamichi. The point I’m trying to make is not all audio gear is pleasing to all. Pick what sounds good to you and jammed on
