Zu Druids low powered tube amp or high powered SS?

Did you have the factory break the speakers in before shipment? How many hours do YOU have on them? They need considerable break-in.

Source?

...and what are you hearing that you feel is lacking?

Give us details. I've heard them in quite a lot of systems, both budget type, and approaching all-out. Have never failed to impress me.

Something might be holding them back...

I would like to know how the Carver sounds if you ever hook it up, sometimes Carver works pretty good, other times not so much.

Druids, generally speaking, do not work well with solid state amps.

They are a 12 ohm load and much more tube friendly than let's say Definition which are 6 ohms and work well with both topologies. Personally, I wouldn't use either the Proceed or Carver on Druids but it might be worth a shot.

Lastly, not all 300B amps are created equal.

I bought them used on AG, so not sure about the Breakin time the dealer said they are not yet broken in. How many hours for Breakin? I also have a TAD-60 which is driving a pair of Mark and Daniels Rubys and that combo is totally like live music, The best that I have ever heard at least in my house. Maybe the Tad-60 would be better?
