I am currently using the current setup: Pioneer VSX-D811S Receiver Sony SS-MB300H Mains Sony SS-C490 Center Sony SS-MB100H R/L Surrounds Sony SS-MB100H R/L Back Surrounds RCA 12" 200W Subwoofer My next upgrade will be a DIY sub, as soon as I get the chance to build it (and sell my RCA sub). After that, i'm trying to decide on a speaker upgrade. I frequent www.harmanaudio.com to keep my eye on refurb deals on JBL speakers. I've recently noticed the HLS615 and HLS810 speakers, both for around $150 a pair. I would probably get a pair of HLS615s as my mains, or possibly the HLS810s. I may also get HLS810s for my surrounds, if i like them (or the HLS615s) performance as mains. My questions are the following: 1.) Are these speakers too good to be true at $150 a pair? I've read really good reviews on epinions, but thought the HT forum would be a more definative source. 2.) Which would you reccomend for mains and fo surrounds? I've always liked the full extension of a tower speaker, even though i'm currently using an extremely large (21" tall) "bookshelf" speaker on 18" stands. I really like the stands i've built, that's why i'm considering the HLS810s as mains, because i could retain the same stands. If i got the HLS615s for mains and the HLS810s for surrounds, i could relocate my current main stands to the back 3.) What center channel speaker would you match with these? An N-Center, S-Center, or something else? 4.) I've also thought about either the HLS615s or HLS810s as mains, then getting the NSP1 package. This way i could use the N-Center, and all 4 N24s as surrounds. Would this be a good idea? 5.) Most importantly, would any of these options REALLY be an upgrade? Or am i better off with what i have until i can afford a significant upgrage (JBL Studios, Paradigm, something else higher end), which may be a good while away? Thanks alot.
