Just because I didn't notice a big improvement in MY system doesn't mean that there wouldn't be one in yours. I'm still using my good ol' Boston Acoustics System 9000 speakers which is by no means a high end speaker set. Perhaps something more elaborate would benefit a lot more from such an upgrade.

I also don't do a lot of critical two channel listening (which seems to be what most people focus on for performance grading). Our primary use is for movies and Netflix and with that said, I've been happy with the performance of the amp. I can't really say much beyond being happy as I just didn't do any serious A/B testing.
