I have something to add about having owned Thiel CS3.5 speakers for over 30 years. I have quite a few friends that remember my system with these speakers as being the best system that they every heard anywhere, including CES and other audio shows. One of my friends finally declared that there is "no way a system 30 years old can still have sounded better than I have ever heard since. I must be building it up in my mind, like a fish story".
Well, about 2 years ago, when my wife bought an extra house for us (I mean that we didn’t move in, she just bought it for later), I decided to set-up in its living room the EXACT same system that I had dismantled about 10 years earlier.
The speakers were in storage, the Cardas Hexlink Golden 5C interconnects were here, the CAT preamp was there, and may favorite tube mono amplifiers for the Thiels were also in storage. Once all put back together, I invited a few of these old friends over to hear the "famous" Thiel system again. We all agreed, it was STILL the best system we have ever heard. Wow, with carefully chosen associated equipment, the CS3.5 speakers sound like magic. They make magic, with their immaculate imaging, impressive dynamic contrasts (both micro and macro), super low and accurate bass (with the EQ), and reproduction of the natural timbre of real acoustic instruments. My new CS3.7 speakers are not significantly better in these particular qualities. As a whole, they sound quite similar. I doubt that any 2.x speakers can beat the CS3.5, but I have two pair of 2.x now, that I have not heard yet, so I will find out soon.
I know that some of you are thinking, including Tom, "No way his 30 years old CS3.5 speakers can sound as good as 3.7 speakers with Audio Research Classic 120 amps and a $20000 Audio Note preamp." Well just don’t underestimate the benefit of 20 years working on a system, carefully comparing amplifiers and preamplifiers, using current VERY high-end cartridges (e.g. Koestu, Benz Ebony LP, ZYX, Shelter), and choosing the best sonic match for every single cable in the system. Plus experimenting with AC conditioning, room acoustic treatments, and speaker positioning (in inch increments). Also, since the 3.5s were moved to a bedroom and the 3.7s are back in the living room, I have started the intense tweeking process with them, like I did with the 3.5s.
