| Audio Research Reference Phono 3 versus Nagra Classic Phono I would guess that if you connect a SUT to the MM inputs of an FET/tube hybrid phono stage you are bypassing the JFET gain stage, and in any case, the gain device makes no difference to the SUT or the cartridge, so long as the input resistance is ... | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? You would not achieve a 100R load by putting a 100R resistor across the secondary. God forbid! That would result in the cartridge seeing a 1 ohm load across a 1:10 SUT. But if they inserted a 10K ohm resistor, THAT would result in a net 100 ohm lo... | |
| Turntable suggestions for a newbie Japan, where Technics products are nominally manufactured by a large conglomerate is hardly a 3rd world country. (I say "nominally", because some of their lower end models are apparently now made in Malaysia.) Nor is the UK a 3rd world country, t... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? That video wherein J Carr talks about many aspects of cartridge use and design reveals also that Benz helped Lyra obtain cantilevers, in addition to the brands named above. | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL I am not sure you can measure input capacitance in such a simple manner, because the input capacitance is only present when current is flowing. That information you probably need to get from the manufacturer. I am impressed if your meter can meas... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL Mijo, don’t forget to add in the input capacitance of your phono stage. In proportion to their gain factor all phono stages present a capacitance, both tube and solid state types, especially those with op amp input stages. | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? I think you mean 470 ohms, not 470,000 ohms. But you would not want to load your Sussuro at only 100 ohms. | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL Also, the idea of loading at 100K ohms vs 47K ohms should not be considered in isolation from the load capacitance, which is what I was getting at when I mentioned that 47K ohms with ~200pF and 100K ohms with ~100pF give about the same RC constant... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL If you have a good multimeter, just set it on capacitance and then place one lead on the hot and one on the ground on the connector, OR if balanced IC, then place one lead on the plus phase output (pin2) and the other lead on the negative phase ou... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL I made no recommendation at all, particularly with respect to loading the Shure. I’ve only related my own experience with loading MM (particularly the Grace Ruby) and high output MI cartridges other than the Shure, in much more recent years. A rea... | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? I have to suspect Icon installs a resistor across the secondary of the SUT, thereby reducing the load seen by the cartridge to 100 ohms, instead of the expected 470 ohms. Either that or the base load resistor at the MC inputs is 10K ohms instead o... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL It occurred to me that Grace recommended 400pF capacitance for the Ruby. 400pF with 47K ohms gives the same RC constant as 200pF (where I’m usually at, approximately) with 100K ohms. And yet it sounds different. | |
| Turntable Hum And Channel Drop Yes, alligator clips would be fine just to test the hypothesis. | |
| Tonearm Alignment Conundrum In every case and with several tonearms and many different headshells, when I’ve set the arm wand level (parallel to the platter surface), the top of the headshell is also level. So my guess is that your headshell is not mating properly to the arm... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL I think I got the idea from you in the first place. Then I tried 100K where before I used 47K. This may have been with the Grace Ruby, but I am not sure. Anyway, 100K was obviously superior to my ears in my system. |
