If your coming from T.V. speakers only. You may find yourself going louder than usual, due to realising the T.V.s speakers are just plain awful.
The 4400H should be enough for now it is regarded highly. By many reviewers.

As for price to power ratio the Axiom ADA Amps are hard to beat.{Quality is top notch} Emotiva and Monoprice are other high powers to look at.

Cheers on the beginning of a fun journey.
