I have to agree wholeheartedly with Paulyh assessment of the 505u. What Paulyh described as the sound of 505u was exactly the same kind of feeling I got from hearing it.
I heard it driving a pair of Monitor Audio Platinum 100 bookshelf speakers. And you know what. It makes me want to give up on tube amps. I have never heard amps that got a better bass control and I have heard a lot. It has the warmth that you normally associate with tubes but yet has the clarity that tube amplifiers at its cost couldn't match
It still has a typical Japanese character where music often comes off sweet and full bodied just like Accuphase and Marantz. But I would rate the 505u ahead of them and by a distance.
To illustrate how good it is. It leaves me wanting to give up on tube which I have been a fan for over a decade.
