EDIT: The title is supposed to be - Surround Sound - Worth it? If a mod happens to read this, could you change the title? -Thanks Here's my current system setup- Receiver: Onkyo HT-R410 Speakers: Sansui SP-5500 vintage I also have HKB6 bookshelf speakers sitting around as well as a Sansui 771 vintage stereo receiver. I was previously using the Sansui receiver to power the Sp-5500 speakers, but I found the receiver's amp was noisy and not very clean - perhaps in need of reconditioning. Plus the Onkyo sounds great with Dolby Digital and DTS, even though they're downmixed to stereo. My question is - is it worth it to spend $300 buying a center and a sub to get a complete 5.1 setup? I am thinking that it might be better perhaps to get a higher end home theater receiver first or a kick-a** sub. Ultimately it is of course my decision, but I would like to hear your thoughts. Thanks for your time, -Jonathan.
