Hmm I was actually considering upgrading from this:
Kenwood VR-507 - DD/DTS/DPLII/CS5.1 - 100wx5 - S-video switching - Universal Remote
JBL N-Center
JBL N26 (2)
JBL N24 (2)
Note the Northridges look extremely small in those pics, I was surprised at how big they were when I got em. The speakers were upgraded from the original Kenwood HTB because they sounded like shite! I plan on keeping the sub because it's heavy to ship. I promise this setup + a decent sub will blow you away compared to your old one

The Kenwood HTB + Northridge speakers is a route many of us budget-conscious HTFers have taken.
My price is $300 + shipping. Then buy a powered sub locally when you can. I'll include about 40' of 16g speaker wire. I even have the boxes for all this stuff but I'm sure shipping will be cheaper if I just include the accessories and manuals.
Anyone interested just PM me. Default dibs goes to Lucian if he wants it.
