Just completed re-doing my home theater. Initially I was going to just replace my JBL speakers with newer models, but then thought, screw that, if I'm going to invest the money, I'm going to get a great system. Through much research (plus some experience in the past), I decided on Definitive Technology as my speakers. As all of you on this thread know, they're hard to beat for the money, although with the bipolars you either love them or hate them. Anyway, since I live in the middle of nowhere (Rushville, IL), the closest high-end AV dealer is >75 miles away, and I take care of my two daughters who are both under 2 1/2 years old, I took some risks and purchased my entire system on the internet. I got a used pair of BP10b's off eBay, a new (but through a liquidator) pair of BPX surrounds from audiophileliquidator, a used CLR 2300 off eBay, and a gently used SuperCube II off eBay. I'm happy to say that they all came as advertised, fully functional, and all I can say is WOW! I thought what I had before was enjoyable, now all I want to do is watch all my DVDs again. I literally had no idea what I was missing before. Of course, with speakers of this quality, I had to upgrade the receiver. While I would have loved to go with separates, I don't have the space, so I went with an Onkyo TX-SR703 from 6th Avenue (authorized Onkyo dealer) to replace my Yamaha RX-V630 (now relegated to the basement system). Night and day difference. Now if my wife will just stop telling me to turn it down during a movie!
Added to above: I also need to mention that my huge love of music has been greatly enhanced by this system. Because of my daughters, I've ripped my entire CD collection (approx. 1000 CDs) into MP3s. I play the files, encoded between 128 kbps and 320 kbps, from two sources; an iPod photo (analog, but easier to compile playlists), and a Lacie Screenplay Multimedia HDD (coax. optical, but slow and clunky). With my old yamaha/JBLs, the difference between sources was gigantic, but even the Lacie was vastly inferior in sound quality vs. CD. Anyway, even playing MP3s through the iPod now sounds fantastic. I'm currently re-ripping all the CDs into 320 kbps to the Lacie, because I seriously cannot tell the difference anymore between that and the CD original running through the Onkyo and the Def Techs. And yes, obviously this will be a long-term project since I only get about 3-4 hours/day of naptime/evenings to do this, and yes, I am definitely going to copy two separate backups on other external hard drives. I am NOT copying all these CDs again.
