| Cartridge Loading.....Part II OK... lets try a different tact since i do not think ground (be it virtual or real) matters in this situation. I am simply relying on Ohm and Kirchoff for this ideal case. Take a 30Ω cartridge and hook it up to an ideal voltage amp and then anot... | |
| Cartridge Loading.....Part II The question cannot be answered at all if current amplification is used. Why not? Consider the case to be an ideal current amp with the appropriate series resistance added so the input impedance is 5Ω. In this gedanken world the ideal voltag... | |
| Cartridge Loading.....Part II The topic of this thread is cartridge loading and it only makes sense to look at it from the two terminal perspective of the cartridge without concern of the "technology" used to provide that load. There are two basic extremes of operation of a ... | |
| Cartridge Loading.....Part II Ralph, The two statements you quoted from me seem to align well with each other and I was unaware that there was a different versions of ohms law for static vs dynamic loads At any rate, Moncreif threw off his numbers by using a 5 Ohm load I ... | |
| Cartridge Loading.....Part II I didn’t mention a dead short and was only referring to the two terminal impedance the coil of a cartridge sees. Any reference to ground be it real or virtual does not factor into the load seen by the coils. Surely there has to be an actual input ... | |
| Cartridge Loading.....Part II I do not think the value of the loads chosen invalidates the test. Sure it may over-exaggerate things in the traditional sense in the voltage realm. When you consider the proliferation of "current mode" phono inputs in vogue the 5Ω value isn't so... | |
| Cartridge Loading.....Part II So, if PM did not shows from where comes the IMD only JC is rigth? I would say no since the two loadings PM shows for his IMD are 5Ω and 100Ω both of which will surely damp any possible LC resonance which would then eliminate the whole RFI aspec... | |
| Cartridge Loading.....Part II @rauliruegas What Jcarr and in parallel Ralph are saying is completely different than what is presented by moncrief. They all agree that loading has no effect on the measured frequency response of a cartridge but any similarities end there. Ral... | |
| Cartridge Loading.....Part II Ralph The loading has no effect on the cartridge other than making the cantilever harder to move. Isn't that essentially suggesting that compliance has no effect on the sound of a cartridge? did you ever get a chance to look at the copy of IAR ... | |
| Cartridge Loading.....Part II The lower value 200 ohm vs. 47k ohms means more loading which tends to attenuate higher frequencies. If this were the case it would be easily measured yet I have yet to see this actually documented. Another way to attenuate highs is to lower t... | |
| Benz SLR Gullwing, not sensitive to loading? This is not about whether loading should make a difference. The key statement from the OP is: And there is not the tiniest difference in sound at all. Plus the three tracks even have the same volume level. If there is no change in level on a 3... | |
| Benz SLR Gullwing, not sensitive to loading? As mulveling stated. the difference in output level alone should be clearly audible. If the output level does not change as you apply a 100Ω load you are not making a connection somewhere. A simple way to test this is to simply put a 10Ω load (... | |
| Cartridge incompatibility, Soundsmith and Luxman It was me who pondered that there might be a SUT inside not Lew. I realize that many MC inputs offer a 100Ω option but I found 100Ω as the only option to be a bit odd particularly for something likely to be paired with a 40Ω denon 103. Add to thi... | |
| Cartridge incompatibility, Soundsmith and Luxman Unfortunately the specifications on the phono section are sparse so it is unclear what the input configuration is. The fixed 100Ω value is an odd choice unless there is an internal SUT for the MC input. To further confuse things the E-250 phono ... | |
| Review of Quadratic MC-1 SUT With Comparisons to Other SUTs the core lamination's are a special nickle or steel that has good magnetic properties. That can get magnetized if a DC current is run through it. magnetic transformer laminations are soft magnetic materials specifically alloyed and annealed to... |
