Thiel Owners

First, thanks for the-replies to my post.  
Second, I had some knowledge of the research and painstaking effort that was put into the original speakers but this really expanded my knowledge.  I was leaning towards passing on auditioning these and looking for a non modified pair and that is what I will do.   Thanks again.

Thank You for the reply to dmac67's query. Very detailed and informative, as always.  I hope that you are well this Summer evening.
Have you found a new space for R&D plus Studio?

Happy Listening!

@dmac67 Consider the resale value of modified gear can often be compromised.
As for the compatibility of your Krell 400xi integrated with Thiel 3.6’s:

We can see from the above links that the Thiel CS 3.6’s impedance stays well below 4 Ohms most of the time. We can also see from the above links, that unlike some, but not all (!) of the rightfully famous, for their ability to keep on doubling down power into lower impedances, Krell separate power amplifiers, that the Krell 400xi integrated is not rated for sub 4 Ohm loads, nor could it withstand the rigors of measurement testing into such loads. If your interested in Thiel CS 3.6’s, you would do well to consider different amplification. There are only a few, usually expensive, integrateds that are up to the task; some of the Gryphons and the DanDagastino Momentum amongst them.

Agreed- it would be pretty cool to hear those modified CS 3.6 loudspeakers. There is something to be said about modified Audio gear, in general.

Happy Listening!

JA - my interest is academic. I want to know who made what changes for what purposes with what outcomes and what seems "better" for what reasons.
