Actually, your $5500/pair IS buying a lot of amps. If you are just comparing 200W to 200W then you are totally missing the picture. EACH Ampzilla monobloc has a 2.4 kVA torroid and 100,000 ufd of filtering. When you compare this to some of the other "powerhouse" amps you will get a better understanding of how the Ampzilla stacks up:
The Son of Ampzilla is an amazingly natural sounding amp and is what you hear in my demo room when I play speakers for customers.You do have to reterminate your interconnects into the amp with phone plugs (most IC manufacturers are willing to do so). The RCA to phone adapters supplied with the amp are not very good.I have retired my wonderful Jadis JPL tube pre and run the Wadia 27ix directly into the Son. That means just one pair of IC's between source and amp. The sound is faultless.

The new Ampzilla 2000 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 un-balanced to balanced converter for single ended inputs. Each monobloc has 100,000 ufd of power supply filtering with dual rectification as pioneered in the original Sumo's.The nominal specifications are as follows and are very conservative:Power output –200 watts into 8 ohms at less than .05% of any kind of distortion known to man.Frequency response-- +/- .1db at any power level from 20Hz to 20kHz.Rise time – less than 2usec at any power level up to rated outputHum & noise – Better than –110db below full outputGain – Balanced inputs – 42x (32.5db) with +/- 1 volt RMS inputUnbalanced 42x(32.5db) with 1 volt RMS inputLoad capability – will drive any load conceived by man
The SST website says this:So now I am really confused...what is the real size of the transformer?The info above can be found here:http://www.ampzilla2000.com/Amp_History.htmlGeorge
Just got off the phone with James (nice guy BTW) and he says it is a 2.5Kva in each Ampzilla 2000 and obviously a single one in the SOA.I agree that in either case it is pretty darn big.George
Something's awry here I have also spoken with James, and he is a nice guy and quite the character (see wardrobe).But, now we have three different numbers being tossed around here.James, if you read this, I'd like to see it in print, specifically on the spec page for A2k. I'm sorry if I'm coming off like a shmuck, but I'm down to two choices for my next monoblocks, A2k's or JC-1's. So I take my torroids seriously Size does matter

Dear John,This is all really very redundant. Transformers are rated according to temperature rise. Without this factor, the number per se, is meaningless. Also, the MOST important thing is the AC regulation of the TX. My transformers have 1% AC regulation which is better than anyone elses' on the planet. Also, I rate my units at a core temperature rise of 65 degrees C, which is also very stringent. There are of course a multitude of additional factors (secrets, if you wish) which I will not divulge. Officially, the TX in both my amps can be stated as 2.5 KVA.JamesP.S. By the way, I design all of my transformers NOT the TX company.
Personally, I believe amp specs are fairly important. There are very, very few amps that have better specs than the SoA (the Halcros are the only ones that readily come to mind)
While we're on the topic of specs, the Ampzillas report what appears to be a significant difference in distortion compared to the other products listed. Is this not as important as it would appear?
