SST Son of Ampzilla ii power amp


Hey guys,

I need your opinions, advise, insights & thoughts on the SST (Spread Spectrum Technology) Son of Ampzilla ii (series ii) stereo power amp. The amp receives many glowing reviews from the likes of TAS, Hifi Plus, 6moons, EnjoytheMusic, etc. I know this amp was barely discussed anywhere and isn’t a popular mainstream amps. It is a class AB design with biased into class A for the first 10 to 12 watts. I know it looks ugly as hell but I would care less for the look and only care for the audio performance sound quality, musicality and reliability. Many reviewers claimed that this amp punches way above its price and competes well with many amps costing much more. Well, some reviewers always said that, don’t they?

I’m thinking to buy this amp to replace my Classe Sigma Amp2 class D amp to drive the Monitor Audio Gold 200 5g (latest generation) speakers. The rest of my gears are : Classe SSP 800 preamp processor, Cary Audio CD 306 SACD player/DAC served as my CD/SACD player and DAC. I also have the Oppo 105 universal bluray player used as a bluray & occasional DVD-Audio transport which is connected via HDMI to my Classe SSP 800.

What do you guys think of the SST Son of Ampzilla ii (series ii) amp and how would it compare with my existing Classe Sigma Amp2 class D amp? I know they would probably sound different. Any other options out there I should consider? Any input, insights & thoughts are welcomed. Thanks in advance.

I have listened to and sold many of the great brands of hi-fi gear out there, and I have owned tube, hybrid, and solid state amps. So my comments below are informed by this experience.

After much research and consideration, I opted for a Son of Ampzilla II amp as the final amp for my system. The amp sits between my Wyred for Sound DAC 2 and my Living Sounds Audio LSA-20 Statement speakers. It proved to be a 'sound' decision.  ;-) (My virtual system post is at https://systems.audiogon.com/systems/9586)

The amp offers the best aspects of tubes and solid state amps and it has no sonic weaknesses. It presents a very low distortion and cohesive sound across the audio spectrum, and sounds equally good at low, moderate, and high volumes. The best characterization of its sound is that it sounds like a great class A solid state amp. I think its lack of distortion coupled with a high level of cohesive detail is what makes many people think of it as a 'warm' sounding amp. 

I am unabashedly biased towards this amp I recommend it without reservation.  

Happy listening everyone!
