| 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... | |
| Linn Bedrok LP12 Plinth Upgrade Davey, You said you can put your stylus into the lead in groove and there is dead silence. All I am saying is that should be the case for any decent turntable at normal listening levels, because one ought not to hear bearing noise (even though be... | |
| Linn Bedrok LP12 Plinth Upgrade Noise once you lower the cartridge onto the LP surface is going to be primarily do to the quality of the pressing and any defects in the stylus shape or tracking, surely not due to the bearing assembly, which noise ought to be way below the thresh... | |
| Pick it Pro Balanced cartridge? real balanced? any good? "Actually both the + and - sides of the cartridge output is what floats." Probably that is a better way to say what I said. I certainly don't disagree. | |
| Pick it Pro Balanced cartridge? real balanced? any good? There have been historically a very few cartridges that for example used a single ground for both channels. Those cartridges (Decca, I think, or early Grado) are inherently single-ended and cannot drive a phono stage in balanced mode. But any car... | |
| Linn Bedrok LP12 Plinth Upgrade Not to beat a tired horse, but when I first read the word "fettler" on this thread, I had no trouble understanding its meaning, owing to our use of the term "fiddling", meaning to mess around with a complex object, and the obvious relationship to ... | |
| Simple tube-use question Remove and clean for sure. There is no useful reason to leave a paper sticker on a vacuum tube. |
