| Thiel Owners Barry - to your question, each model (3) keeps its overall character and intent. The differences are in refinement of execution of that intent. | |
| Thiel Owners Barry - Your speakers can probably be serviced by long-time Thiel service manager Rob Gillum now of Coherent Source Service in Lexington. The O3a is second generation O3 which put Thiel on the map. The A generation dealt with baffle edge diffracti... | |
| Thiel Owners Room sounds really nice. That smallest floor to ceiling dimension is a significant limiting factor to normal playback rooms. Good work with your ceiling treatment. I'll post when I have some feedback regarding bridged mono vs vertical bi-amping pe... | |
| Thiel Owners Pops - What is the power rating of the Macs? Do you use the 4 ohm tap? The CA200 is rated at 200 into 8 ohms and 500 into 2 ohms, so it is current limited, which interests me. Have you used it in both stereo and bridged mono? What is your ceiling... | |
| Thiel Owners I am likewise eager to hear people's experiences. Please cite your amp particulars; this performance would be related to low-impedance behavior. | |
| Thiel Owners I would call a 20' x 20' room large. Square can cause standing wave problems, but openings on 3 sides helps that a lot. No real delineations apply for "large" or "small"; the 'how much power is enough' is an ongoing unknown. But swapping amps is a... | |
| Thiel Owners Sqmlaw - the DR8 and 9 are quite similar except for the power output. If you like the amps and if they don't need recapping, you are better off than most music lovers. Power requirement rises dramatically for large rooms and loud levels. If it sou... | |
| Thiel Owners Happy New Year everyone. This forum has been a focusing inspiration for me taking on this upgrade project. This project has served to reorient my work life more toward music, which has always been important to me, but has often take a back-seat to... | |
| Thiel Owners If I ever get my recapped Classe's back from the shop, I'll report. DR6 pre and pair of DR9 power that I've had since the late 80s. | |
| Thiel Owners Andy - I can share information, but can't send drawings until Thiel Audio's bankruptcy is settled. You are correct; the 2.7 and 3.7 have 3 separate drivers with electrical crossovers, unlike the 2.4 which is electrically 2-way plus the mechanical ... | |
| Thiel Owners Sam - sorry for the dense language. The insight that is somewhat obscure is on the listener-cognition side of the equation. Phase coherence lifts a veil that allows the listener to believe the sound is real, and therefore the sound is subjected to... | |
| Thiel Owners Sam, your experience is consistent with mine during 50 years with myriad amps and signal chains. More power, especially current, works better. One insight is that current lag induces phase lag. In most speakers phase lag is not audible, since phas... | |
| Thiel Owners Remember that if you are using lead solder to be very careful with smoke extraction - lead accumulates and causes brain and nerve damage. Thiel solder is 96-4 / silver-tin, but it is much harder to work than lead solder such as Cardas eutectic. Yo... | |
| Thiel Owners Andy - If you are replacing a few parts and they are accessible, you can snip the lead wires and twist your component leads to those stubs - and then solder. | |
| Thiel Owners Sam - my cap of choice is ClarityCap CSA with potential CMR bypasses. My resistor choice is Mills MRA-12 which is nearly best of form for reasonable cost. Our work is still in process.Main benefits from upgrade include higher resolution, micro-dyn... |
