| 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... | |
| Thiel Owners Ob, Used gear offers great opportunity, with some cautions. Most gear, including Thiel speakers use electrolytic capacitors. Even very high quality E caps have a projected life of 25 to 40 years. Rob says he has never seen a Thiel outright cap fai... | |
| Thiel Owners Jon, I accept your perspective. The doubling itself is less important than is having the required power at 2 ohms. So, the most important factor is how well the amp performs at 2 ohms, which is the critical impedance of Thiel designs. That said, t... | |
| Thiel Owners Ob, the Mac you cite is current-limited by definition. If it doesn't double from 8 to 4, that means there is insufficient power to do so, whatever combination that power comes from storage capacitors (instantaneous) or transformers (sustained). Be... | |
| Thiel Owners Prof, you're right about the "hollowing effect". Phase cancellation is a central problem making first-order implementation very treacherous. The output of 2 combined drivers produces a lobe which cancels or augments output when the "listener" is n... | |
| Thiel Owners Prof, as a technical note, that wavy driver behaves better than any of the previous cone drivers as well as supports the tweeter wave-form launch very nicely. Therefore the direct series crossover path is simpler than any previous Thiel driver. Ji... | |
| Thiel Owners For the record, the CS1.6 is on my upgrade list, as it has sophisticated, all-Thiel drivers and represents the pinnacle of the 1-series (pre-coincident driver) and there were thousands of pairs produced. There has been no expressed interest in th... | |
| Thiel Owners Dn, sounds like a wonderful setup. I don't know those amps, but can offer some general thoughts. This group might offer opinions of the Lyngdorf. Read between the lines, it might be class D and/or digital amplification, which you would have to son... | |
| Thiel Owners Hello folks; just letting you know that no grass is growing under my feet. I am making good strides toward first test samples. The CS2 2 development has dropped back till autumn and the PowerPoint and CS2.4 are now the first-tier projects. The big... | |
| Thiel Owners Indeed wire is a squirrelly stew. Considerable knowledge exists, much of it in the realm of very high tech-space research-at the fringe of measurement. High end audio "found" wire as a new frontier in the 1970s and some very good work has been don... | |
| Thiel Owners I have no actual knowledge of Goertz except that Jim used it in the lab as a reference quality cable. The industry works in many ways and each company develops its own value-style. Thiel valued long-term mutually sustaining relationships built on ... | |
| Thiel Owners Thiel has used the same internal wire since the 03 in 1978, before the time that wire became a component. We identified a high purity, long crystal, oxygen-free polished wire in teflon jacket, developed for the aerospace avionics industry. That wi... | |
| Thiel Owners Regarding impedance, it is what it is. The designer chooses the nominal impedance for fundamental reasons and then optimizes all parameters around those dirver particulars. In particular, Jim needed low inductance drivers for high-end extension an... | |
| Thiel Owners Harry, I neglected to mention that Rob Gillum of Coherent Source Service is capable of doing the job if you prefer that route. | |
| Thiel Owners Harry, I have looked long and hard at which models to hot-rod. My choices center on Thiel-developed drivers and a long life horizon going forward. Although the 3.5 was a defining product in its time, it doesn't check enough boxes. The drivers are ... |
