| Thiel Owners magnet7 - yes, that 8uF tweeter blocking cap is the best bang for the buck. Psychoacoustically, its function range in the midrange and treble is where our hearing is most sensitive. | |
| Thiel Owners For those interested, the original 03 EQ was similar to the 01 as a fixed point boost at 30Hz, enabling the speaker's -3dB point at around 27Hz while maintaining 90dB sensitivity at 8 ohms (6 ohms minimum). Those early EQs had less sophisticated c... | |
| Thiel Owners Jeff - my memory was unclear about the ported 03. Please confirm NO equalizer. BTW, it's great to know these speakers have given you joy for so long. They were made in our first garage shop on the little farm outside Lexington, about the time we ... | |
| Thiel Owners Jeff - here's a lesson from Thiel history. All our products shared the same goals of flat frequency, phase, time, and dynamic response. The family signature is quite similar between models. Also, along the time-line, new technologies were invented... | |
| Thiel Owners magnet7 - Others here might help you find your best brand fit. Here’s my broad input. Those woofer electrolytics are in shunt (shaping) resonance circuits which are the least sonically important. The Solen 1uF bypasses are very good. The styrene u... | |
| Thiel Owners Some of the power resistors can benefit from 25 watt versions, thus 2x12watt. This resistor thing was a short suit for Jim (in my opinion), since the compact layouts can only afford so much real estate. Modeling software can ID those candidates; s... | |
| Thiel Owners Beetle - I looked extensively at thermal dynamics as a source of 'aural congestion', drifting crosspoints, etc. That's where the new layouts came from, which have all the resistors separated from caps as well as positioned over ventilation holes i... | |
| Thiel Owners Adding to Beetle’s excellent summary, here’s a cheapskate trick for the Thiel resistors that you might keep. Turns out, a big part of those resistors’ ’sonic problem’ is the thermodynamics due to their mounting. They are non-inductive wire-wound ... | |
| Thiel Owners @beetlemania re: " Curious if you have an opinion or knowledge about how to pair "main caps" if the full capacitance is not available in a single cap. Is it best to optimize balance between caps (eg, 7+7=14) or is there some degree of leeway (eg,... | |
| Thiel Owners Rob - I can recommend the SonicCap from Sonic Craft that still has the old aspect ratio. Anything Sonic Craft carries has been carefully considered and chosen. | |
| Thiel Owners Stefano - Here are some thoughts from having owned, listened to, appreciated and messed around with CS3.5s for decades. You are correct that anything you do will have sonic consequences; and also that some of those consequences will take you close... | |
| Thiel Owners Relax Beetle - let us work through the permutations with apples to apples comparisons. When the smoke settles and the fog lifts we might see some place for some PUR caps, but you're sitting pretty till that time. Spin some tunes with your wife. | |
| Thiel Owners Beetle and Rob - In my conversations with DG, the CMR thing was problematic in that in some ways the PUR (CSA with thick end caps) outperformed the CMR. Dave was instrumental in pushing CC to develop the PUR+, which is a CMR with thick end caps. F... | |
| Thiel Owners Duramax - the 2.7 has been talked about informally. As the last of the True Thiel designs it is very mature and, unlike other products including the 1.6 and 3.7, XO manufacturer didn't go to China. Thiel made those in-house with traditional Thiel ... | |
| Thiel Owners Pieter - Higher voltage acts more like film-foil and sounds better. But the upper frequencies have far less power than bass, so difference is negligible. Also the 28uF is in the final station where voltage has been previously shunted to ground. Al... |
