Ben,
Was it our tech that did the A chain alignment? If so please let us know as he should have caught that one.
Your problem could be caused by a number of things.... Bad bearings, hooked sprocket, bad flywheel that has leaked out all its damping fluid, lateral guide arm problems, gear box problems, etc. The SH-1000 is the best sound reproducer ever made and its not at all difficult to get them running correctly. Its better to repair it than switch it out. If it wasn't our tech that was there might I suggest that you call our tech as he may be in your area I this comming week...... he is very familiar with that reproducer.
As to the Century Sound head, yes its possible to run an X-L on one, it easy to set up, parts are off the shelf, and its actually a pretty good combination although a bit unorthodox, its just that the R-3 is no where near the reproducer that the SH-1000 is.
Also, I would trash that POS DTS and get a real processor... its also possible the problem might lay there...... While you're at it shoot the person that sold it to you...! Those processors just don't sound good no matter how well they're set up. Even a used USL JS processor would actually sound better that the DTS.

With this comment I have to present a interesting topic: I help open a 14 plex, then was booth manager/engineer here. Shortly we opened up this 14 screen, my highs started to get massive distorted like nobody's business in about half of the auditoriums. It was extremely nasty.
My HF driver diaphrams were all cracked and had to replace all of these defective drivers since at first, we thought we had a batch of bad drivers. Got them replaced, but soon, cracking diaphrams came back. Got a tech in and he was doing some EQ'ing and noticed that in the 500hz range that there was a dip in the display. During the install, the crossover settings weren't done right (for SR-D usage). Plus some of the switches were set to parallel instead of bridged (or other way around, I can't truly remember...)
My other side of the problems were with the DTS-6AD units where the units were sent out broadband instead of Bi-Amp, thus every freq from Sub info to HF's were heading in to the HF channel-why my HF diaphrams were busting like crazy. The crossover chips weren't installed on the top board and had to get those chips to send the units into Bi-Amp and correct this problem.
Was lotsa of fun with all of this... -Monte
