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.
