Bella Extreme 100
100 watt Mono Bloc Amplifiers
by Response Audio

Discontinued

Carefully designed to deliver a well-balanced musical presentation and long-term listening pleasure, the Bella EXtreme 100  monobloc amplifiers combine the finest sonic attributes of classic tube amplification (midrange accuracy, smooth tonal character, and smooth yet extended high-frequency resolution) to enhance the listener’s emotional involvement with the music.

As with all Response Audio products, the Bella Extreme 100 amplifiers utilize a unique circuit design that demonstrates our beliefs in using premium parts, shorter signal paths, top notch build quality.  Every pair of Bella EXtreme 100 monobloc amplifiers are proudly hand-made in the USA and carefully tested, inspected, and packaged before being sent to you for your listening enjoyment.

Over 3 years of research and development has gone into this product with a goal of becoming a true reference product. The Bella EXtreme 100's are providing you with 100 watts pentode and 60 watts in triode of glorious 6550/KT88 tube power which will drive most loudspeakers with grace and ease.

 The craftsmanship is absolutely first rate, featuring hand built point-to-point wiring right here in our New York facility.

 Don't mistake this for yet another mass produced, off the shelf product. As you can see in our construction details, we use some of the finest passive components available in the industry to assemble these products. Only the highest grade V-Cap and SoniCap Teflon capacitors  are used in both the coupling and power supply bypass locations. A combination of  Mills non-inductive and Dale Vishay 1% resistors are also chosen for critical areas. We use resistors with a wattage rating that is 2x to 5x higher than required to provide the quietest presentation with the lowest noise floor.

 All components and construction was chosen for it's sonic integrity rather than designing for a price point.

 Our attention to detail and the quality of construction within the EXtreme 100 amplifiers is every bit as detailed and thorough as any Response Audio product to leave our facility and possibly among the best in the industry.  When matched with the right associated equipment, these amplifiers become and exceptional choice for even the most discriminating listeners.

 Cable manufacturing guru Robert Lee of Acoustic Zen bought a pair of Bella 100's after showing his new Adagio loudspeakers with them at Rocky Mountain Audio Fest 2006.

 Don't need 100 watts of power? Not a problem. With just the flick of a switch, you can have 60 watts of sweet triode sound driving your speakers.

TRIODE VS PENTODE:  Some say Triode is the ‘BEST’ way to listen to tubes.  Although the output decreases, usually 40%-50%, the bandwidth increases, the distortion decreases, and damping factor increases as compared to PENTODE operation. What sounds best? Let your ears decide.

World debut review of the Bella EXtreme 100 monobloc amplifiers

"....Try as I might to find an alternative, the conclusion I consistently have about these amplifiers is that they are much closer to perfection than any other amplifier in my experience. In fact, I find them faultless...."

The Bella EXtreme 100 amplifiers debuted and were very well received at the 2006 Rocky Mountain Audio Fest. 
Read the details and results!!

Due to recent increases in manufacturing cost over the past few years, the Bella EXtreme 100 chassis were costing us much more as compared to only 3 year ago. Add to this increase in cost of just about every component we utilize in the construction of these products and you will understand why we are no longer able to offer them.

We had the option of almost doubling the cost or make compromises in the construction. Neither of these options were something we or our customers wanted to see so we decided to discontinue the Bella 100 mono blocs.
