Main speakers are MB Quart S530 4 ohms 85db
Center MB Quart S330 4 ohms 90db
Rears are Paradigm bipole 70' (or something like that)

Anyway, I bought the NAD T743. Did not hook it up yet. Read the manual and noticed the dynamic power mathced my Denon 1800.

Was thinkng of returning the T743 (wife made me due to cost) and buying the T753 (recomended by salesman). Anyone recomend the T753 for powering my Main 4 ohm 85db speakers?
