Good character, depth intonation, clarity, smooth, live...

Nothing at all...
With the money I spend for this Butler, I never feel disappointed.

Perfect... sounds great,smooth,detail,open,clarity.

This amplifier satistied all my needs and pation about what is a car audio should be.

Firstly, I bought this amplifier to increase the depth of vocal.
And I got what I want.

For those, who ever imagine to own a tube amplifier; should buy this product.
