Ron,
There is little point in going for this receiver as it has THX certification that you will be paying a lot of money for. THX is a high quality (pioneered by George Lucas) surround sound that can only be made use of if you have THX certified speakers and reciever and as far as i can tell the bose speakers do not have this.
I would recommend that you look at alternatives without THX certification as they will be much cheaper or else get a new set of speakers.
I have a Yamaha THX receiver and Jamo THX speakers and the sound is awesome, so if you can afford it get new speakers!!
