Thiel Owners

@thoft, PM sent.

@thoft, I once heard B&W 802’s through a Counterpoint hybrid amp playing the most glorious chorale music at one of StereoExchange’s older locations in NYC. A huge space. It was the one and only time I remembered enjoying B&W’s. I had become somewhat friendly with a few of the staff. After about 20 minutes the salesman waived his hand over the Counterpoint and said it was getting hot and he proceeded to shut it down. He then whispered in my ear that these things have a tendency to burst into flames. Something that I’ve heard oft heard repeated over the years since then, 

Regarding concrete repair - look for expansive grout at Lowes, etc.

I am confused about expansive grout. everything that I've read says its purpose is to open cracks. can you elaborate in a little further?

Wait burst into flames? What in the hell? You serious @un

Expansive grout is a waterproof cement product with adhesives, designed to expand in a crack to seal it. It may be called foundation crack sealer, wet-stop or similar.
Those original CS7 baffles were portland cement concrete, which continues to shrink over time. (Its first cure cycle is 7 years, when its shrinkage is nearly over.) Grouts add gypsum and/or other expansive masonry ingredients to achieve various controlled expansions. I don't know what exact product Thiel (or the nearby repair shop) used. But a millwright or masonry contractor should point you in the right direction.    Disclaimer: After my time at Thiel
