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.
