“When I went to hear the speakers demonstrated, they were powered by an Class A/B amp which retails for several £000s. To my ears, there was no discernible difference between it and the 1200AS2 and I am absolutely delighted that I was able to invest the bulk of my funds into high quality speakers. You’ve helped me get the best possible sound system for my budget. Thank you.

“Hi Guntars. I bought the ICEpower 1200AS2 after watching your video. And it does exactly what it's supposed to. From buttery smooth to rock-hard, depending on the music. And it does it really well. Unhindered dynamics and very natural, pleasant with a beautiful timbre, perfect for enjoying music for hours. And it passes everything through perfectly, so even the smallest changes in the chain become "visible." An ultimate tool”

Reviews
"Hello Guntars. I bought the ICEpower 1200AS2 after watching your video, and it does exactly what it’s supposed to do. From silky smooth to brutally hard, depending on the music material — and it does it really well. Unrestrained dynamics, very natural, pleasant, with a beautiful tone that lets you enjoy music for hours. And it passes everything through one‑to‑one, so even the smallest changes in the chain become 'visible'. An ultimate tool. My journey is probably over… unless… 🙃"
"I received the TCR1200-C and assembled my ICEPower 1200AS2 amp with little trouble despite my fumbling fingers and poor eyesight… When I went to hear the speakers demonstrated, they were powered by a Class A/B amp which retails for several £000s. To my ears, there was no discernible difference between it and the 1200AS2… You’ve helped me get the best possible sound system for my budget. Thank you."
"I have been happily listening to music for two days now. The only thing I can say is WOW! … The amp is dead quiet mechanically and electrically… Not the slightest hint of noise with my ear right against the tweeter. Well done on your part… I am very glad I took this route. Thank you very much."
"After watching your video about 1200AS2… I purchased one… then another to make them dual mono. This is where I experienced the tremendous improvement… I’ve had A, AB, tubes, tpa3255 etc… Since having the 1200AS2 dual mono I am not thinking about Purifi or Nilai. The sheer power and sound quality will impress anyone… The amp grabs the speakers and tells them exactly what to do."
"Guntars. I was lucky enough to discover your channel… For someone with a limited budget but a large appetite for superior sound, I totally lucked out finding you. You have transformed my listening from one I could have only dreamed of, for an affordable budget. Thanks man."
