Have you tried Red Wine?

I have been using a Red Wine Audio Clari-T amp with my Zu Druids and a sub. Fantastic performance. Without the sub I felt it was quite good but a little wimpy on the bottom. Now I have big time performance from an inexpensive battery powered low power amplifier. I would like to know if others have had similar results and has anybody tried the new Signature 30 I'm thinking about buying?
