How to use 2 channel setup with 5.1 setup

Add a decent AVR (I reccomend the Onkyo AVR 905, used), a center channel speaker and surround speakers (preferabaly matching) and you are off to a great start. Your MF A5 has a HT bypass, so you're good to go.

PS-
Use the pre outs for the front 2 channels, with the MF A5 providing the amplification.

Kal, The MF does have a HT bypass (as correctly stated by Srwooten). SrWooten - I take that I will need to add additional amplificaiton for the center and rear channels? I expect I would then be able to switch off the HT amps and AVR and just listen to two channel, correct?

Also by matching, you suggest staying in the Gallo line with surrounds and rears?

Is there an opportunity to use the Gallo 3.1 subwoofers in HT mode lieu of a dedicated sub?

Thank you for the feedback, as I do not have any experience with the HT side.

SR Wooten - just read read your repsonse. Got it - that the AVR provides the additional amps for center and rears.

Also by matching, you suggest staying in the Gallo line with surrounds and rears?

Yes

Is there an opportunity to use the Gallo 3.1 subwoofers in HT mode lieu of a dedicated sub?

If they have built in subs I think it shoud work great. I don't have personal experience with the Gallo 3.1's.
