SST Son of Ampzilla ii power amp

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!

Their amps are great, not heard a word of negativity about them.

    Few warranty things, some electronics have a half soldering, loose connection during shipping.

years ago I bought the Crown studio ref II, 780W a8 Ohm, and so on.
  Came with a 30 amp plug, which I could not use.
sold my grail amp at a slight loss to a nice guy, he emailed me one channel had some issues, I said, I just received it 2-3 weeks prior, it still had plastic on everything.    Mailed me back in a couple weeks, thanking me, it was some loose wire, or a solder joint, a very minor fix. I hope he still uses it, I wish I had the 30 amp outlet for it, would not have sold it.


damn, I always ramble, the Ampzilla Is a serious piece of iron!!    Use it, enjoy!  I looked at them years ago, but, could not $ a new one, plus they don’t come up for sale used often, .....this tells you something.

 The good stuff comes for sale on a blue moon,....
I happened to find my monoblocs’ for a very nice price, so I think it’s a great price.     Only bought a few new pieces, Onkyo m-504, b&k pro-10mc newer model)
cerwin Vega D-9s’. Altec Lansing m508 or the m510 pair, they were only here for 2 weeks, amps used were my mistake, why they are not still here, they were a great speaker, and that dome midrange had nice subtle sound when needed, and a wicked crunchy vicious guitar when called for.
   I miss those, big time.

 They had the carbon woven woofers, some tweet and some mid, 2 8” or 2 10”.  I think I had the m510s’.......damn now I’m kicking myself, they would have sounded so good with a good amp.

   I’ve kicked my own arse over the years for dumb mistakes in audio.


   Yet again,....sorry


Ampzilla is amazing, if you can afford one, get one, let her break in and please report back....

I have gone through many amps over the years. I was using BC REF500M’s, which are awesome Class D amps. Then, I found a great deal on a SOA II and since I had wanted one for some time I jumped on it. It has transformed my system. From going through numerous amps in the same system my past experience told me that there will be some differences between amps., but they tend to be incremental and subtle. After having the chance to listen to many of my go to albums I can honesty say that the experience with the SOA II has been transformative. First you will notice that the sound stage and imaging are insane. You feel like you are stepping into the music and the artists are right there in the room with you. From there you will just have that sensation of there being more of everything from the decay of the cymbals to the heart stopping bass. The vocals are so life like you just want to reach out and touch the artist. If you have the speakers and DAC to do this marvel justice I would recommend the SOA II without hesitation.

My setup: Auralic Aries - BC DAC 2.7 - Wyred4Sound ST Preamp- SOA II - Acoustic Zen Adagio Speakers + Martin Logan Sub

Has anyone heard the SST SOA II vs Parasound A21 or A23+ ? Thank you

I find this thread interesting, since I’m in the market for a new amp. Any sense of how this amp would compare with an AVA Set 500?
