Son of Ampzilla II
A New Son Rises
STEREO AMPLIFIER
SST proudly presents the Son of Ampzilla II stereo amplifier. This redesigned Son is the third generation in concept and design and features many new ideas and improvements over previous generations. However, we made sure to respect and retain the traditional circuit topology that gives the Son its revered sonic signature. The end result is a masterful fusion of classic and cutting-edge design.
The new Son boasts an exceedingly low noise floor and the same power supply capacity as in our flagship Ampzilla 2000 Second Edition amp. Another noteworthy feature is a unique grounding procedure that insures absolutely no ground loops. The measured power output of the new Son of Ampzilla II is a potent 220 watts/channel into 8Ω (double the original Son of Ampzilla). And the listening pleasure? Immeasurable.

“My time with the Son of Ampzilla II has been both a revelation and a privilege. I have never found such a high performing solid-state amplifier at this price point.

The [Son of] Ampzilla brings a burning sense of immediacy to the table—one that I don’t recall hearing from any other amplifier. When the CD ended, I realized I was breathless. It had been like I was at a concert. I wasn’t paying attention to anything except the music, but I did notice the [Son of] Ampzilla’s extremely deep soundstage and imaging to die for. The soundstage extended from around each side and from top to bottom. It was incredible.

I had never experienced this effect with any other system. It was a continuance painted on a remarkably deep center stage. The [Son of] Ampzilla II turns out to complement all the flavors and nuance painted by the Thoebe II.

“
When it comes to the sound, [the Thoebe II and Son of Ampzilla II] remind me of the Ambrosia and Ampzilla 2000: the same quietness, smoothness, transparency, dynamic range, and that elusive impression of body, dimensionality, and solidity.... As found with all exceptional equipment, there is on the best recordings a gratifying impression of lifelikeness and vitality, simultaneously relaxing yet wholly involving.
— Paul Seydor, The Absolute Sound

The Son of Ampzilla II performs at the top of its price level and above with a very neutral, near-characterless sound. I found it honors music at least as well as the Levinson No. 532h [$8,500], Parasound JC-1 [$9,000/pr.], Manley Neo Classic 250 [$9,000/pr.] or Bryston 7BSST2 [$9,200/pr.].

In the final analysis, the SoA handle might be just that one ‘t’ shy of SotA. That’d be shorthand for state of the art and utterly brilliant
— Srajan Ebaen, 6 Moons
“
Offering consummate ease, composure, and iron-clad stability, it also has a wonderful impression of body, dimensionality, and solidity that is reminiscent of [James] Bongiorno’s final solo amplifier, the Ampzilla 2000…. [U]sed alone or paired with the Thoebe, this is a real high-end bargain that requires no apologies.

Will say this, I’ve owned a good many amps, some more expensive than the Son of Ampzilla II and I absolutely love this amp—it’s spectacular.
