If full range speakers are selected for the front/center/right channels then one sub will work fine. Linn AV 5140 speakers are very attractive and take up less floor space than your average high end metal stand for a bookshelf type speaker; they are also full range with right amplification.
Agree on Marantz comments; many better choices out there. Used Integra receivers are a good value and sound pretty good. Arcam AVR200 receiver is a good unit, too; and the AVR300 much better (but much more expensive).
Hard to beat a used REL Strata II for about 600/650; it is one of the quickest and most musical subs around. You never know it is there when it is set correctly. It also has a fairly small footprint and is fairly unobtrusive in the flat black finish. I use one with Gallo Dues (f/c/r) and Gallo Micros (rear surrounds) and an Integra 7.3 receiver with excellent results. I slimmed down from a much more powerful home theatre system with larger speakers (Thiel CS 2.2) and don't miss it a bit with this Gallo system. The receiver is good enough that I've already removed the Bryston amp I was using for the front channels and just use the amps in the receiver.
A great pair of stand mounted moniters would be Spendor 2/3; beautiful sound and fairly easy to drive with a solid 30 watts or better. These speakers do not present a difficult load so you don't have to have Krell/Levinson type gear to do a good job (although it never hurts). The smaller Spendor 3/1 is also very, very good and less expensive. Harbeth makes spectacular speakers that stand mount for a bit more money.
