Well, I finally accomplished my goal. I decided some time ago that I wanted to put together a complete 7.1 setup, featuring new JBL product. Living up here in the "wilds of Canada", it is very difficult to purchase JBL stuff, let alone hear/see it in advance. I decided that I wanted the Studio L-series.
I started calling JBL, asking which companies sell their wares. After many unreturned emails and messages, I got a cell number for their local sales rep. Nice fellow, he put me on to a little local store. Very little stock, and not much interest in selling it to me. More time on the internet. More time, more unreturned calls/messages. Finally decided to take a leap of faith, and started ordering on the internet, sight unseen.
After a few challenges with the online vendor (took my money, didn't ship the product), boxes started arriving. And it is now complete:
L890 fronts
LC2 center
L8400P sub
L820 sides
L830 backs
And: two spare sets of L820s, in case a future house layout is more condusive to wall mounted speakers, instead of big towers.
I'm extremely happy with my new system. The speakers sound amazing, the quality and asthetics are what I expect from JBL, and I've received tons of compliments from vistors to the house.
Sure wasn't easy to accomplish this goal, though.
