I just wanted to post this happy news -
I found a set of LSi15's on the Charlottesville, VA, Craigslist, linked below, for $550.
A scratch or two here and there, but they have two-and-a-half years left on their five year warranty from Polk.
The seller seems like a real straight shooter and has more audiophile gear in his house than I've seen in one place in years.
I'm traveling on the East Coast and driving back to Illinois soon, but really looking forward to hooking these up to the GFA-555ii I bought a few weeks ago.
I want to publicly thank Skrol for helping me vet a pair of these in Baltimore that I didn't end up getting.
I'll probably be posting questions here to you guys as I try to find ways to best utilize the speakers.
Thanks to everyone for this great forum.
