Arcam AVR600 as 2-Channel

I'm looking closely at this AVR as a 2-Channel piece. It has all the functions I am looking for:

USB / Toslink / SPDIF
Sub Out
Pre Out

I am curious how this performs as a two channel amp. Most of the reviews I find are focused on the AVR capabilities.
Try this review. It's a bit long, but it should answer your questions.
