My Wife and Daughter concur.
Right now...
I'm running the powerhead and the unpowrered version side by side with the exact same settings.
Unless there is another settings being overlooked...
The unpowered head sound and feels more natural and warm. Makes me want to play more!
The powerhead sounds more on the cold and sterile side.
I'm thinking there may be either a settings I'm overlooking on the powerhead OR...
The power amp section somehow detracts from the tone?
