I bought my BATVK30 preamp used here on AudioGon, having never heard or even seen one. Very much out of character for me, but I got so many glowing recommendations from the folks that frequent this site I took the plunge. Quite simply, it's the best preamp I've ever owned and will NEVER leave my system. I was so impressed with BAT, I then acquired a BATVK500 amplifier here as well. BAT gear is terrific stuff. I sincerely doubt you'll be disappointed. Jeff
