Thanks for your opinions!
My Tannoys are pretty warm speakers with slightly rolled-off treble, I'm wondering if a warm amplifier like Denon or Marantz could be a right choice. In fact, I'm more oriented towards Rotel (I'm going to put it on my desk, so the missing remote control won't be a problem), which have a brighter sound.
But I don't know anything about its headphone output, while I've read from you and other people that Denon and Marantz one is very good.
It's a rough decision! :)
