Great sound and very powerful

Drives all of my headphones and iems with ease.

Has replaced my smsl desktop as my go to amp

Alston Maccow

This a very is wonderful portable tube amp. I use it as a desk amp more than I do as a portable. This is my first tube amp ever and the sound is so great. No matter what headphones you use and iems you use it’s got a wonderful tone. I’ve not even had to use gain switch even using my HD6XX. I was a bit worried buying this amp but I’m really glad I did. I’ve now going to change most of my system and upgrade to another tube amp and this is because I like the sound of this amp
