I heard their amps at the Audio Karma fest in Michigan. The small room setup they had sounded fantastic, pushing Gini systems LS3/5A monitors with bass modules. This is just my opinion, but I think it was one of the standout rooms of the whole show. I tend to rant and rave about a specific design feature in tube amps: adjustable global negative feedback. This is one of the features these amps have, and without it, your stuck with a feedback point that may not be optimum for your speakers. My tube integrated has this feature, and it's amazing how much difference is acheived with this adjustment. I think these relatively unknown amps are VERY good. Hope this helps.
