Hi!
Interestingly, I was just about to post a question regarding the First Sound Deluxe preamp and line conditioners. I've had my FS (which I LOVE) for about 4 months, but after 1 month I started to hear clicking and popping sounds (bad tubes?). I replaced the tubes on my headphone amp (an Earmax Pro) but that didn't help and was now wondering if maybe the noise is due to my having the FS plugged into a BPT line conditioner. Bottom line, I would stay away from the line conditioner and plug the FS directly into the wall.
