I have some Beyerdynamic T90s arriving today and need a new amp to go with them as I think my Magni 2 Uber will be too bright. I have a limited budget and would really like to try a tube amp. I have pretty much decided on the Little Dot Mk. 3, as it's the cheapest one with good reviews, and I can buy it locally in the UK. Just one thing is holding me back, I have heard that it can be noisy at high volumes. That's a big turn off for me, as I listen to my music at high volumes pretty much all the time. Has anyone heard it with the T90s? Is it noisy with these headphones? Any help is appreciated.
