I recently bought the H300. To be brief, I am very very impressed. I had been looking at the Pass Int-30 and Int-150, but the former didn't have enough power for my insensitive speakers, and the latter didn't have the same rich sound.
The H300 solved the problem--and then some. It has a remarkable level of transparency, and the mid range really is extraordinary. I don't know how they've done it, but the soundstage has impressive breadth and depth. I have not heard a solid state amplifier with this kind of soundstage.
As an aside, it is also a more conventional size. So, it goes in my rack/cabinet. Most outstanding integrateds are now getting pretty wide and deep. Everything about this speaks to luxury--and convenience.
We all wonder about the reviews. Here is a product that really lives up to the buzz. And you can lift it!
Bravo.
