UltraSonic Studios consists of me, Tomas. I have this hobby of building amplifiers. This is my way of displaying what I build and sell to the public.

I’m an audiophile but even more an enthusiast and tinkerer. I just enjoy building these amps and take great care when I build. I was a PC-modder before I changed over to audio so aesthetics as well as sound quality is very important to me.

I was mentored by Mika Kalm (known as MrCurwen on forums such as DIYAudio and Head-Fi.org), the circuit designer of these amps. He taught me almost everything I know about audio electronics. So a huge thank you to him!

Warranty / Guarantee

As we build all amps to order there’s a no return policy. If something should happen to your amp, and you’ve followed the instructions, we’ll repair it for free within one year, but we can’t pay for shipping. If the amp should arrive “DOA” we pay for shipping as well.
