Tubegroover - in the off chance that you have internal quality problems with the unit, it can easily be fixed by anyone with electronics and soldering experience. In fact, I think my preamp is much better after going to a repair shop. The Engineer (Scott Frankland of Wavestream Kinetics) who worked on my preamp made some very good modifications to my preamp which were simple but effective.
Thinks like separating the internal wires better, sheilding a few of the non-critial wires, putting the unit on a scope and fine tuning the Left and Right gain, etc really made a BIG difference in overall performance. Having Scott look at my preamp and do the fine tuning cost a whopping $50 bucks but the return was outstanding. I would recommend owners of Supratek products take them to someone who has built amps/preamps professionally to learn if there are any quick and dirty ways to improve the performance.
I think Mick's recent "extended" schedule for delivery represents his commitment to increasing the quality of his products. When I ordered the preamp, Mick was turning these out in less than 2 weeks. That has changed signifcantly of late and I expect his more current products are higher in initial quality as a result.
