ALF, that is a fine looking build.

You have given me a deja vu experience. Before I decided to go with the 828 based system I was very taken with some of the high-end JBL designs. The K2 S9800/SE I seriously considered, using Altec components, until I came to my senses.
I changed my mind about the 828 and used the 828 panels I had to go BR/MLTL.

I got this close to building the JBLs:

Have you considered a project thread? I would like to know more about this adventure.

Cheers, Marshall.
