Awesome review out in The January 2012 Absolute Sound on these as well as the matching preamp, the Ambrosia. The Ampzilla 2000's are their PRODUCT OF THE YEAR. They said they offered the same performance as super amps selling for $100,000.

They summed up with:
"The Ambrosia and Ampzilla are by any standard statement products that can take their place among the finest amps and preamps that money can buy. At $15,000 the combo is far from inexpensive, though that figure does include two excellent phono preamps and a headphone amplifier. Reflect, too, that there are competing electronics exceeding $100,000 that give you far less of everything. To those who find it impossible to believe components priced as reasonably as these can possibly be as good as those costing a whole lot more, I only say "they are". Please audition with your mind as open as your ears." If I wee closing up shop tomorrow as a reviewer I would buy them and live happily ever after."

Call me to discuss pricing on these superb amplifiers as well as their preamps and the new soon to be available phono stage.

We are now selling the Spread Spectrum Technologies Ampzilla product. The new fully balanced Ampzilla 2000 Second Edition power amps are exceptional. They are now available in black with chrome insert as well as original blue with gold insert. We really like the new black look.

As a dealer all SST products have the 5-year US factory warranty.

These new Second Edition MK 2 amps use a new upgraded driver circuit design that reduces distortion even lower than the original 2000 design. It also adds a second set of binding posts for biamplification. Rated power is 300 watts in the new units.

The new Second Edition MK2 amps typically produce 340 watts into 8 ohms. They will drive any load of any speaker. They do 540 watts at 4 ohms and are stable below 1 ohm.

The 12ga power cord is welded on for the best connection. No need to use an expensive after market cord with this amp.

All the transformers are custom built and designed by James Bongiorno himself. He is a trained transformer designer and his designs are superb. Real world noise levels are super low. Compare these amps with any solid state amps made as they are that good. Read the info below for more details.

We accept Visa and MasterCard as well as money orders. Read our AudiogoN #1 rated feedback and call 770-667-5633 with questions.

The following is from the Ampzilla website:

-POWER OUTPUT
16 Ohms - minimum 150 watts 20Hz to 20kHz
8 Ohms - minimum 300 watts 20Hz to 20kHz
4 Ohms - minimum 500 watts 20Hz to 20kHz
-Total T.H.D. & I.M. Distortion: 4-16 Ohms less than .05% @ any power level up to rated at any frequency or combination of frequencies between 20Hz-20kHz.
-Input Impedance and Sensitivity: 1 volt R.M.S. across 50kohms for 300 watts into 8 ohms on the unbalanced input.
(note: the impedance value can be adjusted to any value up to 1 mega ohm-consult the factory)
+/- 1 volt R.M.S. across +/- 70kohms for 300 watts into 8 ohms on the balanced input.
-Input selector switch for balanced or unbalanced
-Frequency response and power bandwidth at rated power
8 ohms - better than +/- .2 dB 20Hz to 20kHz
4 ohms - better than +/- .3 dB 20Hz to 20kHz
-Stability: 100% stable @ any load angle 0-90 degrees,
capacitive or inductive, regardless of wave shape
-Damping factor: Greater than 250 at 20Hz
-Noise: Better than -120dB relative to full rated power

-Protection Power switch/circuit breaker 4 DC power supply fuses with indicators
-Gold plated input and dual output jacks
-All steel 14 ga. Chassis, powder coat finish Peak clipping indicator LED, thermal LED
-The entire amplifier circuitry (except the power output stages) is contained on one main drive card which also contains the input jacks. This means that the amplifier is completely upgradeable with future circuit improvements.

The original Ampzilla set a standard, which has been copied, in topological form, for almost the last 30 years. Obviously something must have been right about it in the first place. Subsequently, the Sumo balanced topology has also been copied for the last 10 or 15 years.

The new Ampzilla 2000 2nd Edition is a radical departure in amplifier topology. Not many designers can make a claim like this. The only other designer capable of true innovation is Bob Carver although his application of technology and marketing go in different directions. Needless to say, James has created something truly new and innovative. All that can be said is, "It's about time."

The new Ampzilla 2000 2nd Edition uses a completely new variation of the Forward Gain topology to achieve unprecedented improvements in linearity. As a matter of fact, the new circuit is so smooth, that it can be actually listened to OPEN LOOP, WITH NO FEEDBACK. Of course, we aren't going to make it that way. The PROPER use of feedback is necessary in order to tie down all of the operating points so there will be no variations in performance from unit to unit.

The new Ampzilla 2000 uses 12 250-watt output devices per monobloc. This is 3 times more devices than the original Ampzilla. In addition, since it is a monobloc, there is a separate 2000VA transformer for each. In addition, the amount of heat sink radiating area is 3 times greater than the original meaning that there is NO fan. Also, the B+ and B- supply fuses are EXTERNAL. Also, The entire circuit is totally balanced from input to output although there is a totally and uniquely new unbalanced to balanced converter for single ended inputs. Each monobloc has 100,000ufd of power supply filtering with dual rectification as pioneered in the original Sumo's.

These are North American amps and cannot be shipped to Asia.

The nominal specifications are as follows and are very conservative:

Power output: 300 watts into 8 ohms at less than .05% of any kind of distortion known to man. Typically 340 watts into 8 ohms

Frequency response-+/-.1db any power from 20Hz-20kHz.

Rise time: less than 2usec at any power level up to rated output

Hum & noise: Better than –110db below full output

Gain: Balanced inputs 42x (32.5db) with +/- 1 volt RMS input

Unbalanced 42x(32.5db) with 1 volt RMS input

Load capability will drive any load conceived by man

Some other details are as follows. All transformers are our own design and are made in house. All input and output jacks are gold plated and of the highest quality. The line cord is 12 Ga. with "welded connectors" instead of crimped. All internal connectors are gold plated.
