Thiel Owners


I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!



Thank You for the update on Mr. Rob Gillum. I would like to read more about Walter Kling. Is he alive and involved in Audio? Retired?

I hope that you are well and ready for Thanksgiving next week.


Happy Listening!



Thank You for being a valued member on the Panel. And addressing silvanik's 3.6 tweeter (driver) query.


Happy Listening!

Tom, thanks again for your valuable hints. I can extend the sweep up to 24K that's the limit in REW signals generator, I will do it as for your suggestion. I'll take the measurements separately L and R channel in order to compare the result, maybe the issue I think to have is only in my head....hopefully!

Awhile back someone asked about Thiel binding posts, for which I don’t remember seeing an answer. From my limited perspective: In the beginning we used a post with minimal metal (rhodium over brass) and plastic caps. We got a lot of flack for "cheap binding posts", which in fact they were not. In the CS5 development in the late 80s we revisited those posts and chose them again rather than larger beefier, gold-plated ones. That was before we realized the hazard of eddy currents caused by greater cross-sectional area relative to the input and out wires. As we worked with Finite Element Analysis, eddies in voice coils came to light and we changed from aluminum to nomex. But it seems those lessons were not applied to binding posts, but I wasn’t there and can’t comment on whether attention was paid.

I see a progression to beefier posts in later models. My CS1.6s look like gold on brass via the file test.

My present work identifies the binding post as significantly upgradable. I developed a CDA101 (best available) 5mm bolt connector, but am getting some GR-research tube connectors for test, which should be better yet. They place the wire ends almost touching while adding very little bulk with a thin tube of CDA-101 copper. They look like what I would have designed if Danny Ritchie hadn’t beat me to it.

I have learned that signal path integrity matters quite a bit.

JA - you asked for more about Walter Kling. As I’ve mentioned here, Thiel Audio grew out of an intentional community and its wish to employ ourselves in a mutual undertaking. Besides myself with my wife and toddler daughter, there were my brother Jim and his girlfriend as well as Jim’s school-friend Walter Kling and my fellow Marianist Brother friend Fred Collopy. I had established some viability as a designing craftsman and included Walter in our Conceptions Design Studio. Kathy took on Marketing and relationship-development. Fred was a very early computer pioneer - everything about computers was pretty new in the late 70s. Fred signed up for business development. He later went on for a masters from Wharton in Decision Science and a PhD in Entrepreneurial Development. Walter was a multi-talented artist-craftsman with proficiency as a painter, potter and sculptor. He later went on for a degree in Architecture and practiced that until I wooed him back to Thiel Audio.

Of note is that none of us would have signed up to attempt Thiel Audio without the group commitment to combine all talents and risks for the common goal. We were in our 20s, and along with enthusiasm, change is what happens at that phase. Fred gravitated toward his advanced education and we all absorbed his roles, more or less. But his talents and inputs would have been more than welcome. Walter’s wife had left him with two young children, Jeremy and Jennifer. About 5 years in, he ran afoul of Jim’s alpha-male requirements. His departure, around 1980, was devastating, especially for me. We were moving out of our farmhouse beginnings to our "real" industrial space - a time when Walt’s forté of fixtures, tools and methods were needed. That all fell to me in addition to my teaching-training-coaching - process development responsibilities. It’s hard to overstate how much and how varied is the work required to push the limits, to try the untried and grow a company without outside capital or resources. Jim was an extraordinary designer, but those designs must be implemented in effective and reliable ways, every day, all day. Walter was part of that equation and his absence nearly cost us our company. One hundred hour weeks became the norm.

Around 1987 we expanded from around 5000 square feet to 15,000 square feet including moving everything while adding new capabilities and doubling capacity, all without missing a day’s work. I was able to hire Walter as construction manager for the physical plant part where I took on the logistics, project management and production design part. It worked. (Rob Gillum came on in that expansion as a young rookie and spent his working life in most of the aspects of manufacturing.) The next few years included cementing Walter back into the company, where he remained until Jim’s death in 2009.

Companies prune their PR around the story they want to tell. You’ve rightly heard a lot about Jim, but there was a strong team around him making the whole thing work. Walter was a central player on that team.
