Thiel Owners

You could be lucky and arrive at a great sounding system by trial and error. But this is a situation where experience with measuring pays off. Learning to make valid measurements pays dividend in the long run.

So, Tom, do you then agree with Rob about the SI-1 Integrator , that it's a waste of time and not reparable? I've located one that the owner claims just stopped powering on one day and hasn't worked since.

Some testing results with the AHB2 (in mono) and CS3.7 from last night.

Tmsrdg - my knowledge of the SI-1 Integrator is all hearsay from the same sources and reviews as you have. I might add a little more: that Jim and later operatives after his death tried unsuccessfully to develop a troubleshoot-repair operation. Jim was a master intuitive repairman - he could troubleshoot most any circuit in a few minutes and fix it. I don't know what level of effort was put into solving the repair need for the various electronic compontnts. Short answer is that I know very little about the SI situation in particular, but that in general I am working toward a comprehensive repair solution.

One final SmartSub question: if I were to use one of the Thiel SmartSubs with my 3.7s, would I need, foregoing the SI-1 Integrator, the passive crossover "tuned" to the 3.7? Does such an item exist?
