Thanks...new Bryston is out my financial position...does the Portal have any pre-outs?

No pre outs as the Portal has no preamplifier section. It is about as basic an integrated as you'll find. It has four line inputs, tape out, volume control, balance control, bonding posts for one set of speakers and a pretty good headphone out. If versatility is what your looking for, look elsewhere. This thing is built for quality sound at low price.

Portal...if no pre-outs...how would one hook up a sub?

You can't hook up a sub to it.

You CAN hook up a sub to it. Just use one of the better quality subs with high level (speaker output) inputs
