Which one will have a greater effect on my HT setup? A new sub? Or new Amp? Probably need both.

    Depends on what you have now.

    Get rid of the bi-wire, get good cables and jumpers, add a 2-channel amp.

    I think you're doing more injustice to the 703's by under powering them than whichever movies you watching low end bass.

    Am I missing something? On the mobile app and not seeing a signature. From the above post, I'll assume the 703s are bi-amped on an AVR, and in that case, I'll agree with @rpf65 : use the pre outs and 2 channel your mains with MOAR PaWR!

    I would say a better sub.

    An amp would help, but it's not like he's trying to drive some A9's with an AVR or something...

    I agree. For HT and using the 703's, I'd go for the better sub/prefer subs first.
