| Thiel Owners I'll try to find out something from Rob about the 2.7 vs 3.7 failures. Same driver.Thieliste, good investigation. In the day Thiel, especially the CS5, was very successful in Japan. Luxman amps were the clear choice in ultra high-end systems. They... | |
| Thiel Owners Ron, your listening levels and amplification are very appropriate / safe. So something else is going on, perhaps bad drivers, but sometimes cables can induce amp misbehavior that adds stealth distortion. I can't troubleshoot, but I will try to fin... | |
| Thiel Owners Ron, all of your failures sound like overheated voice coils, either delaminating or in the case of humming along, being loose enough to squirm on the former. The cause is most probably being fed a distorted / semi-clipped signal. The first driver ... | |
| Thiel Owners Ron and all. I placed a query to Rob via phone message this morning. I will post what I learn. This information is indeed germane to all on this board. | |
| Thiel Owners Ron, shorter cables are always better than long. But parallel (not twisted) conductors like Goertz are inherently capacitive. If there is a problem depends on the amp. But Thiel's low-impedance results in more current being drawn through the cable... | |
| Thiel Owners The Goertz design is high-capacitance, which may cause some amplifiers distress in the trans-audio high frequencies, which produces down-reflected audible consequences. Correcting that capacitive load makes the amp run truer to form. | |
| Thiel Owners The most common oddity from a woofer is the bottoming of the suspension: the spider hits the basket plate. Thiel's short coil is out of harm's way from bottoming on the back plate. The voice coil adhesive is high-temperature. So, unless you overhe... | |
| Thiel Owners I like spade connectors. | |
| Thiel Owners I don't know models, but I know that Jim used Goertz flat cables in the development lab as his reference. Jim's perspective was that cable performance is cable business. He felt that Goertz performs cable business the best he found. That may seem... | |
| Thiel Owners I don't know that gear, but I have some relevant experience. First, with regenerated power with good specs and enough storage, it doesn't need to be reconditioned. Proper regeneration is proper power. When mixing and mastering music and burning fi... | |
| Thiel Owners Dan, I don't know that amp. The power specs look great and they withhold the lower impedance specs due to AC-mains overload with all channels firing. Nothing like a real audition to prove its merits to you. | |
| Thiel Owners dspr, my recollection (unreliable) is that there were no electrolytic caps in the CS5. Film caps are stable or get better with age. I'll keep an eye and ear out to confirm my suspicion. Does anybody know? | |
| Thiel Owners thielrules, troubleshooting is a hands-on undertaking. I'll speculate a little, but the problem needs actual triage, both speakers and the eq.The deep bass looks like the green channel has the eq and the red channel does not: textbook 12dB/octave ... | |
| Thiel Owners thielrules, I can't read your attached files nor do I have a 3.5 schematic.Although the role of caps is to block low frequencies and the woofer circuit doesn't have caps in its series feed, there are some smaller values in the shunt circuits which... | |
| Thiel Owners Thos, Replacement models are generated to push the art, grow the company and generate new interest. The old products aren't really old or defective, in fact in many ways Thiel designs out-do many contemporary products. The 2.3 and 2.4 are conceptu... |
