SST Ampzilla 2000 v2 vs Son of Ampzilla II


Looking for something new to drive my Dunlavy SC-IVas and am considering SST's Ampzilla offerings. My preamp is an ARC SP3. Hoping someone with a bit more exposure to them could share what they'd consider the pros and cons of each to be and whether the 2000 monoblocks are worth the extra money.

I have just ordered a SoA2 and Ambrosia 2000 preamp.  How do you like your setup.  Any regrets.  How do they sound?  Are you running a sub? 

I find it quite strange to read such detailed comments about certain amplifiers when the amplifiers mentioned by name do not exist.

All "Son of Ampzilla" amplifiers under the SST and/or "Ampzilla 2000" badge are stereo amplifiers with absolutely no, repeat no potential for bridging into a mono amp.  How do I know?  Because James Bongiorno told me that each channel is already bridged and on this particular circuit two bridged channels cannot be bridged again into mono.  Maybe the designer of the amps was wrong but that seems like a bad bet to me.    

So for reader's edification, every reference suggesting the existence of a "mono" Son of Ampzilla (from SST and/or Ampzilla 2000, 2 names for the same company) are simply wrong.  

Not to put too fine a point on this, but this post does not refer to any "Son of Ampzilla" under the GAS banner nor the latest/current SST/Ampzilla 2000 "Son of Ampzilla II."  What I typed may or may not also apply to those last 2 amps; I have no personal knowledge whether those 2 stereo amps can or cannot be bridged.

On a separate subject: Ed Morawski (sp?) in his review typed that dealer John Casler told him (IIRC) that "2000" in "Ampzilla 2000" refers to the transformer VA spec for the mono and stereo amps, not the year the mono versions were released. as I suspected was the case (IIRC the stereo version arrived 2001-2002.)  Further, Ed typed that Casler added that latter versions had 2400VA transformers.  I have no personal knowledge on either of these items. 

Even the current Son of Ampzilla II has 2000VA and 100k mF PS filter capacitance, two specs that IMO have never appeared in any amplifier in a similar price category, significantly more than a current $11k Levinson 5302 stereo amp.   

Have no idea about the bridging issue. I do know that a single SST Son of Ampzilla II effortlessly drives my old trusty Von Schweikert V4s to sonic bliss.😁

Ditto on the misinformation regarding the ‘Son of’ being monoblocks. The Ampzilla 2000 monoblocks are available in v1 and v2 and the v1 I owned for a couple years sounded fantastic driving the heck out of a power hungry pair of Carver Amazing Platinum speakers. As one would expect, the Ambrosia preamp is a great match for the Ampzillas and, in my humble opinion, is actually the star of the show when it comes to this pairing.

 

I was an assembler for a certain speaker brand; the CEO of that speaker company was one of Bongo’s biggest industry supporters. Bongo premiered his new SST/Ampzilla 2000 V1 mono at THE Show with this speaker company, IIRC in the year 2000.

I owned two SST Ampzilla 2000 V1 mono. (AFAIK I never heard V2 but IIRC everyone who expressed familiarity with V1 and V2 unanimously preferred the latter.)

Bongo released SST Son of Ampzilla stereo 2001 or 2002. This is worth what you paid for it: IMO Son stereo was considerably more refined and musical than 2000 V1 mono, whose only advantage was more thump and horsepower. (Note Bongo rated Son 400W @ 2-ohm w/2k VA transformer and 100k uF PS capacitance, extraordinary or beyond in this price class.)

Being the loudmouth I am, I voiced the above opinion often to my boss the speaker company CEO. The following is a little foggy after so many years, but IIRC either the speaker CEO or Bongo himself said that Son stereo’s circuit is more refined and musical than 2000 mono V1. Someone (just can’t recall who) later said mono V2 incorporates Son’s refinements. (To further confuse the nomenclature, SST Son II is a superb but completely different amp designed by the brilliant EJ Sarmento of Wyred 4 Sound, who studied under Bongo.)

At some point later, the speaker company CEO purchased a 2nd Son Stereo, one channel from each Son driving each speaker channel.

Around this time Dick Olsher reviewed and raved about SST Ambrosia V1 preamp and SST Son of Ampzilla stereo. Just prior to publishing, the speaker CEO convinced Dick to audition two Sons as described above, using 1 channel from each amp p/c. Dick posted that the speaker CEO estimated that using Son in this fashion (rather than both channels simultaneously) increased output by 6 dB. (That point too is worth the admission price.)

Read Dick’s review, but IIRC he purchased Ambrosia and two Sons. Dick is positively a self-described tube fanatic.
