| Cartridge Loading- Low output M/C Why is it nonsense? I know that I started out by seeing what others were loading the Madake with and it was seeing the huge range of answers that was posted that, to some extent, triggered the analysis process that I have gone through. If you view... | |
| Cartridge Loading- Low output M/C Oh, and I just wanted to say- the Miyajima Madake cartridge designer effectively loads the cartridge at effectively 60 ohms (I know as we have exchanged emails on the subject) using his in house SUT and amps and doesn’t add any cap in parallel- he... | |
| Cartridge Loading- Low output M/C Hi Al, so, let’s look at some simulations of the RIAA stage input.Let’s assume that a minimum capacitance has been achieved of 100pF, which as it includes the cartridge winding capacitances, the internal wiring of the pickup arm, the interconnect ... | |
| Cartridge Loading- Low output M/C Whether to use the extra pole is an interesting question.So, here is some more information, and a repeat of some old information so you can judge for yourself.1. The additional pole serves not only to reduce the RF but also to reduce the deviation... | |
| Cartridge Loading- Low output M/C Unfortunately accentuated dynamics and resolution all too often mean a really nasty peak at the HF. In my experience, getting a good test record and testing the RIAA response can be a real eye opener.Most of the differences in response that occur ... | |
| Cartridge Loading- Low output M/C Just for interest sake, I ran some simulations with an "ideal" MC cartridge with a 5mH/5 ohms coil in conjunction with a near ideal active RIAA design with non inverting amps and the extra pole.The ideal load- the one that results in the closest c... | |
| Cartridge Loading- Low output M/C I may not be a renowned Audio Designer, but I am a somewhat renowned IC designer with credits that include cell phone transceivers and high performance opamps. In truth, the issue with phono stage RF has little to do with the capacitance loading- ... | |
| Cartridge Loading- Low output M/C As the Ortofon is a fairly low output MC cartridge there are generally two components to the frequency response which interact.1. The electrical LCR response.Contrary to what has been said, for LOMC the capacitance, unless it is quite large (in th... |
