I got everything hooked up and calibrated this morning. I am now running a all JBL sound stage plus my SVS Ultra.
Fronts- My new S312 II's pictured with my Pinnacles that have been moved aside. The 312's are 41 inches tall @ 77 pounds.
Center- S Center II
My new S36 II's now my new side surrounds sit atop my old Mitsubishi's
Back surrounds- My Old L-88's I purchased used in '76, still going strong
My first impressions, swweeeeeeet

Only had a chance to run a few samples, a couple CD tracks, and a few demo scenes. One I like to run is on a DTS demo disc that has a Jurassic Park 2 trailer on it. Very good use of all the surrounds with stomping and jungle noise going through the sound field and of course the T-REX!
Not sure what to do with the Pinnacles now, I'll trade for another pair of 312's if anyone has some layin' around. More later.
