I was hoping to find replacement tubes, and I don't think they do sell them at Living Stereo and I unfortunately had a very disappointing experience.
I don't know which member of the crew met (ignored?) me and my girlfriend on Saturday, but the guy couldn't be bothered to answer any questions, give me a demo, or even the time of day when two other customers were in the listening rooms.
Just echoes of the good old, if you are not ready to spend money right this second I am a little too busy, standoffish, high end audio weenie attitude.
I have read good things about his shop so I hope I just got them on a bad day, but in any case the store is very small and maybe an appointment would be best.
