| Teres Turntable/Soundsmith Strain Gauge System Raul, Lloyd Walker always shows his Precision Motor Controller supported by his brass tiptoe-type feet. I mount mine on a set of Goldmund cones that I happened to own, also on an Adonis rack system. For some reason that I certainly do not understa... | |
| Well-Tempered Golf Ball? Chashas1, If you are talking about the new WT table, the Amadeus and it's new arm, I have only seen it in photos, so I will take your word for it. My friend's WTT Reference is more than 12 years old, so I do concede that later models may be easier... | |
| The correct internal-inductance of Windfeld cart.? Axel, To me, the "minimum impedance" spec given by the cartridge maker is not the same as the optimal impedance. Can you name any cartridges where two different impedances are suggested, one for SUT, one for no SUT? In my very limited experience a... | |
| The correct internal-inductance of Windfeld cart.? Jonathan, You are correct. I just did not want to go into great detail on Dave's qualifications. | |
| The correct internal-inductance of Windfeld cart.? Dear Axel, Intactaudio is a professional in the use of transformers, autoformers, chokes, etc, in audio. He is highly respected on other internet forums for his knowledge and unbiased advice. Rather than leaving in a huff, you might be better serv... | |
| The correct internal-inductance of Windfeld cart.? Thanks for your input, Dave. | |
| Geometry for pivot tonearms - calculation errors?? Dertonarm, How then do you feel about the SME tonearms, which utilize a sliding pivot point in order to achieve pivot to stylus adjustments? In the process the pivot to bearing or spindle distance is also altered pari passu. | |
| The correct internal-inductance of Windfeld cart.? Axel, I am often vexed by the same phenomenon-reviewers who comment on the "sound" of a SUT without regard to the myriad of other parameters that affect the result. Particularly egregious is the "SUT shoot-out" type of review, where many different... | |
| The correct internal-inductance of Windfeld cart.? Axel, No one is arguing with your logic, and I am not foxed. I will leave it to Dave (Intactaudio) to comment on the second half of your post. Dave knows more about transformers than both of us. I did learn something from your story, so thanks. | |
| The correct internal-inductance of Windfeld cart.? I learned something. To paraphrase Gertrude Stein, a SUT is not a SUT is not a SUT. | |
| The correct internal-inductance of Windfeld cart.? Thanks very much, Dave. I bookmarked that thread for future reference. But in your experience with primary vs secondary loading does it often occur that the optimal net load for a given cartridge, when you load the primary of the SUT, is radically... | |
| The correct internal-inductance of Windfeld cart.? I really think it's quite interesting and unexpected (to me) that with pre-loading of a SUT, the optimal impedance for the PW seems to be about 10 ohms net, whereas, as you say, without the SUT the PW seems to like 500 to 1000 ohms net. I am not c... | |
| The correct internal-inductance of Windfeld cart.? Axel, Now it is YOU who have misunderstood ME. You wrote, "So, the SUT secondary "sees" the 47k input-impedance of the phono-pre! If you put -another- 47k R (as you implied)". No, I did not mean to imply nor did I think that you have two 47K resis... | |
| The correct internal-inductance of Windfeld cart.? Sorry, you are correct about my math error. 470 not 47. Much better. Your findings as to the sonic differences between loading the PW with NO trannie vs loading it either on the primary side or the secondary of a SUT are quite fascinating, and I d... | |
| The correct internal-inductance of Windfeld cart.? Axel, After I made my post, I re-read yours, and I realized I had slightly missed the point of your question. You might want to read the "white paper" on the Jensen transformer website, where they cover the complex issue of loading very well and d... |
