I planning on actually getting a tube amp I was eying these two the Little DOT MK2 and the Tubemagic A1 because they are affordable for me. I was wondering has any one pair either one with a Beyerdynamic T-90 and if so how did it do. I may roll tube's but I not sure and please dont mention thet Woo audio's or the other higher costing tube amp's as I def wont be getting either one as I don't have a money tree in my backyard and I sold my DT880's to help fund the T90 purchase. The plan is to use the tubes that either one comes with to see how I like them before changing them. I will be using my Audio-GD NFB15.32 as a dac into the tube amp.
