Pure awesome sound can overheat if overdriven but hard to do. I'm a Landscaper in Wilmington and I'm very satisfied with my purchase.

None so far.

The harder you push them the better they sound. Can be driven down to 1 ohm and stable. easy to set up without an EQ. no muss no fuss just loads of power

None so far. tile demolition near me

Large soundstage that is precise, smooth, and tube-like. Best value wins the race and declares the winner. outstanding audio quality. Perfect for Retaining wall blocks NZ long drive!

None . .

Pulls hard from 2000 to redline, makes heads turn, and has little effects of highway gas mileage. I am thinking to use this for a corporate limo service orange country.

Lack of tunability. Stick it on and be happy with what it gives.

This is amazing. I really love it. Fence Contractor

None so far-

These have been great. Saturation is awesome, sound is nice and warm and has been very versatile. No distortion on anything going through the amp so far.

None just yet! -Andrew from http://www.snowremovalwyoming.com

Clean and powerful. Zero problems.

No audio weaknesses. Maybe the price?

I have been using this amp since Nov 2004 and have no regrets about spending the money. It is very powerful, and the sound is smooth and clean. It loves rock, yet is so revealing for acoustical or voices. Sounds great through my CDT Audio ES-643 speaker set. I have had zero problems. This is my first "tube" amp, even though it is a hybrid design (read more on http://www.tubedriver.com/idea.php), so I have no other "tube" amps to compare it with. After having used a Pioneer Premier PRS-X340 and Planet Audio Quadra, I think the TDB 2150 sounds much more natural and clear. I actually like that it has no crossover - less electronics to potentially alter the sound.

No ch for subwoofer

I got the used to be store display amp TDB475 from Butler, and actually it is producing nice sound for midrange and high. The sound comes more naturally with good definition and warm timbre besides its thick sound. I wish the Butler produce the 5 ch amp with a ch dedicated to have big powr to pwr up a subwoofer ( they have 5 ch but the 5th ch is not designed for driving sub with enough pwr ). It is very hard to hear which one better between this & the legendary McIntosh, but possibly this amp has bit better sound quality than McIntosh, well i guess it depends on the listener frequency and timbre prefference. McIntosh has brightness & the TDB475 has softer tone yet a bit thicker sound. both are pretty good in exposing the recording sound detail.

Nothing really at this price point. A fantastic amp.

By far one of the best three car amplifiers ever tried. Butler Blue loves rock but it handles gently every kind of music - really a perfect choice. Smoothness, mid-range lush (needed for rock and voices), super-dynamic and very large and precise soundstage are the charisma of this amp. Worth every cent. Combine it with focal speakers and fast cables and you will not believe the overall quality.
