A good stero amp or integrated for PSB Imagine Ts

Hello all,

Here is my setup:

Arcam AVR300 driving PSB Imagine Ts (bi amped).
PS3/Airport Express feeding optical out to Arcam.

I am looking a good amp or integrated that has HT pass through to drive my fronts. Also looking for a DAC for the Optical sources.

Thanks in advance,
Seenu
