OP, By the way I have a Violectric … I think it is a V281… I had to import it from Germany. This unit has enough current to power a set of Denton flagship headphones. I used it a few times and gave it to my partner for listening to tv at night when I am sleeping. Good high current headphone amp. But lacks musicality.
Ayre makes great equipment. But if you want real musicality, go tube. I recommend a used Audio Research preamp, they are a level above Rouge. And you will hear it. For headphones, I recommend Woo, you get the current and natural musical sound.
