| Calculation verification please In addition to what I and Atma have written, I am most amazed that you hear differences in SQ among resistances of 250, 324, 368, 404, 500 & 600 ohms. I don't doubt you, but I have tried such experiments and never heard much if any difference.... | |
| SUT for AT-OC9XSL? IF you add a SUT, then your signal voltage would be very high, as you suggest. For example, a 1:10 SUT between the cartridge and phono would result in about 10V signal voltage at the OUTPUT of the linestage, not at the input, so yes, you would hav... | |
| Calculation verification please I must have misunderstood from the get go. I thought your original question was what parallel loading resistors would create a 375 ohm load. Answer is still that it's not possible by introducing a resistor in parallel with 47K. I personally would... | |
| SUT for AT-OC9XSL? Can you be more specific? I am not sure what you are trying to convey. For example, "way lower" for what? Since your CDP or whatever other high level sources you use is likely to put out at least 1V in signal voltage, generally up to 2V, I would g... | |
| Turntables currently considered top of the range. Do you know what they are ? Inna, No one of us thinks he is biased, in the sense that he or she thinks he or she cannot make an objective judgement. And yet.... | |
| Calculation verification please I refuse to read the gibberish, but if you place a 51K resistor in parallel with a 47K resistor, you will get around 24K resistance. If you use your 1:40 SUT into 24K resistance, you will end up with a phono load of about 15 ohms. In other words, ... | |
| Turntables currently considered top of the range. Do you know what they are ? Woots, what spectrum? And by the way, which Kuzma? No one here mentions any direct drive TT. The Dohmann Helix is the only belt drive I’d have in my system, if I were limited to BD. | |
| SUT for AT-OC9XSL? With no SUT, you have a net of 68db gain, which means the cartridge output will be multiplied by -2500X. If your cartridge makes 0.4mV, the output to the amplifier from the linestage will be about 1.0V. Adding a SUT is overkill. Try without. | |
| Calculation verification please Not possible. With a 1:40 SUT into 47000 ohms, the cartridge will see a -30 ohm load. The sum resistance of two parallel resistors cannot exceed the value of the lowest value resistor. So any resistor you place in parallel will reduce the impedanc... | |
| Turntables currently considered top of the range. Do you know what they are ? Was just thinking it’s ironic that the LP12 is denigrated for the high cost of upgrades but Clearaudio gets away with it because for $20,000, you also get a name change. | |
| SUT for AT-OC9XSL? A phono stage with 70db gain does not need any SUT to amplify your cartridge; I say this without knowing precisely the voltage output of your cartridge, but just about any LOMC with output 0.2mV or higher will be more than adequately served by a 7... | |
| SUT for AT-OC9XSL? You are leaving an important parameter out of the equation. What is the gain of your phono stage? What is the output of your cartridge? If you can make do with a baseline step up transformer that has a one to 10 gain ratio, then there are a myriad... | |
| Is there usually a dramatic difference between $5k and $10k cartridges ? My today self is amused by my then self for even taking the trouble to assemble 6 pairs of power cords, let alone doing the listening test. | |
| Is there usually a dramatic difference between $5k and $10k cartridges ? Conversely, I evaluated 6 different power cords providing power to the bias supplies of my Sound Lab ESLs. I did not expect to hear much if any difference, but I did hear a hardware store power cord (the stock cord. provided by Sound Lab) come in... |
