I had the pleasure of listening to a pair of Jud's vzm100's in my home for about a week, and I can honestly tell you they are beyond a doubt the best amplifiers I have ever heard. The resolution was incredible I was able to hear into the music, I told Jud when he left my home I didn't think it was possible to hear music with such clarity, his amp and preamp combination is wonderful, so I will be saving my pennies until I can have them for my own.
