Great sound and very powerful

Drives all of my headphones and iems with ease.
Love the warmer sounding tubes.
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

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.
