| Thiel Owners Thanks for sharing the summary of the upgrade choices, Tom.@rojacob if you successfully upgraded the coax feed caps to SE then I can’t think why you could not also build an entire new board. You must have taken the coax board out to access the sol... | |
| Thiel cs2.4 upgrade to cs 2.4 se @andy2 holco has uploaded the schematic. The 14 and 28 uf caps are in the feed. Note the SE version gets full values in single caps whereas the original added 1uf bypasses (ie, 13+1=14). The 43 is a subfeed. Those big ELs are in the shunt position... | |
| DAC's....Ayre versus PS Audio Charley had an ear !,,,,Indeed! Good stuff. | |
| Thiel Owners @andy2 lots of upgrade info this this thread also. In particular, look for posts by Tom Thiel starting about March 2018. Quite a lot to read and there probably isn’t any one post with the latest info but worth your time if you’re serious about an ... | |
| Thiel cs2.4 upgrade to cs 2.4 se After much research and consideration, Tom Thiel has settled on Clarity CSAs for the upgrade. He even has a custom low voltage version to replace the electrolytics. I am going to also try Multicap RTX bypasses (1%) on the coax board. Progress on m... | |
| Thiel cs2.4 upgrade to cs 2.4 se Yes, please share a description of sonic improvement. Nice work, though. And thanks for the pic. I suggest replacing the resistors, too. I upgraded my sandcast OEMs to Mills MRA 12s. A nice sonic improvement at low cost ($100). My resistors showed... | |
| Thiel Owners Ah, Bose! *Now* we know the rest of the story. The CS2 2 is dead. Long live the CS2.2! | |
| Thiel Owners Thanks sharing that interesting history regarding Thiel and Vandersteen dealers, Tom. I’ve read most of those journals Hardesty wrote and edited and he was certainly a fan of both brands (and not a fan of Wilsons, Pipedreams, etc). You might look ... | |
| Thiel CS2.4 to what? My 2.4 upgrade path is to rebuild the XOs. Working with Tom Thiel, I plan entirely new boards, maybe reuse a single 1uf bypass cap. Even the coils will be replaced plus probably going to use Cardas terminal posts. The 2.4 drivers are hellagood. I ... | |
| Thiel Owners My early plans were influenced by some other threads here regarding aftermarket caps and, more substantially, by Tom Thiel's comments here. But other than, maybe the Mills MRAs, all of the current plans and component choices are from the mind of T... | |
| Thiel Owners @andy2 Other than the Clarity SAs in the coax feed, there is reason to think your Lexington XOs are superior to later iterations that were sourced from China. That said, you might still consider upgrading the components if not doing a full rebuild... | |
| Thiel Owners Regarding access to XOs for the 2.4, here are Rob Gillum’s instructions to me:“The crossover can be accessed through the passive radiator opening. The base is not removable, as it is screwed, and glued. To access the crossover, you must remove the... | |
| Thiel Owners Pretty much all designs have trade-offs. You can reduce, if not eliminate, them by throwing more money at it but real-world speaker design is a series of compromises. Sure, Wilsons can play loud as hell, but at what (sonic) cost? The smaller midra... | |
| Thiel Owners CS7.2 (and 3.7) is just behind the very best speakers I’ve heard, and at a fraction of the price. I suspect Tom Thiel’s XO mods will narrow that gap. I’m itching to finish my 2.4 upgrade. I suspect I’d have to get something like a Vandy 5 carbon t... | |
| Thiel Owners learn the 2 ohm behaviorHi Tom, Stereophile has measured both Ayre models i have owned. Soundstage might have also measured the AX-5 but maybe it was the amp rather than integrated. Charles Hansen was not a fan of power ratings for amps. Here are ... |
