Jeff is absolutely right! The Supratek (if too many options are added) can be a dog. While the circuit Mick designed is relatively simple, additions like "theater throughput", single box chassis, XLR outputs, remote control, etc. In the early XLR equipped units, Mick used the wrong connectors - and added some kind of transformer which was supposed to boost the XLR output and at the same time lowering gain to accomodate what he thought was the "right" way to do theater throughput. The results were not exactly great. I think Mick has resolved some of the issues but I expect that the more you add to the original specification the more potential you have for problems.
Also, Mick builds all the preamps by hand and as fast as possible which has at times resulted in paint drips, loose/cold solder joints, etc. Much of this trouble happened in a time when Mick was turning orders around in 2 weeks - today Mick has upped the turn around time and I think it's now 3 months.
He has a great product and I hope his current business plan includes much better quality control. Again, I want to reinforce Jeff's comments above. Do some research and talk to Mick about it before you order - or while waiting... :)
