Congratulations! yeah, I'm in love with the system. I ran some test tone warbles and it sounds like the LRS pair are making a little bass hump in the 60-80Hz region, and a pretty sharp dropoff below that. Makes it easy to integrate my off center subwoofer, because that hump localizes things well in the soundstage. I set the woofer to come in around 60Hz and the level a little lower than that hump (matching the LRS output in the 100-200Hz area), and the integration is much better than I expected. A single REL 5/Ti. Okay, that's all speaker talk.
I need some time to really let loose to get the Khartago singing. Also thinking about putting it into a 2' x 2' cabinet which has a front glass door. Doesn't seem to run hot, and I'll make sure the rear top vents properly, but I'm a little concerned about in-cabinet heat. Don't want to melt my disc collection.
