Thiel Owners

Tomthiel,
The idea is to connect the chassis of the unit's to ground, not the coil's of the unit's, will find out how when I remove them.

So, it seems you may be grounding the driver frames?
Thiel drivers since CS2.2 in 1990 use Faraday networks / shorting rings in the voice coil / pole piece structure which should cancel stray fields. But, stray residual eddy currents are possibly in play.  Please report your findings.

Correct,  I meant the driver frames, the results will be easy to check when unplugging the ground connection.

Btw, sorry for my crooked English.

Tom, I feel really good about your balanced, sensible approach to both theoretical and practical considerations to increase audible sound quality. I have become more cautious with assuming that when people make claims of improved SQ they have done their homework. Please include double blind comparisons to establish audible differences.

Rules - I appreciate and concur with your concerns. You would be pleased to know the level of verification we employed at Thiel. Serious science.

But there is this other dimension. In my acoustic guitar design and archival recording I have identified an accumulation factor. Recording engineers and piano techs and other technical artists also experience this phenomenon. When on a particular path of exploration, guided by both cognition and intuition, there are many choices which are not provable or even discernible. But a conglomerate effect becomes identifiable / meaningful over time. There are so many subtle factors contributing to the overall result, that each of them could be ignored or over-ruled, but they can matter in their aggregate.
