| Made first sale and don't know how to get paid If you have not received payment, then you ought not to have to pay Audiogon, unless or until that happens. I just sold an item on Audiogon and THEY told ME not to list the item as sold until after I got paid. So perhaps you listed your item as so... | |
| Higher Impedance MC Carts on Transimpedance Stages? The inductance of an LOMC is trivial, in the sense that it’s very low, on the order of 1000 times lower than MI which is already much lower than MM. Your acquaintance is probably happy because it works and he has yet to try an LOMC with truly low ... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Small point: I did not mean to declare definitively that LOMCs can fail to produce realistic piano music because of low compliance resulting in mistracking. I certainly do not know that to be the case. I was just offering that as one unsubstant... | |
| Higher Impedance MC Carts on Transimpedance Stages? Hagtech, In your equation, I assume R is the internal resistance of the cartridge and L is the cartridge inductance. Since you speak of "bandwidth", "f" must be bandwidth. Further I assume R is in ohms and L is in henries. I must have something wr... | |
| Higher Impedance MC Carts on Transimpedance Stages? Nothing blows up. The mating would be inefficient as the internal impedance of the cartridge exceeds the input impedance of the BMC, which we think is around 2-3 ohms. Thus some of the signal voltage derived in the Kiseki would be lost to ground. ... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Mijostyn, You wrote, "The one huge advantage of high output cartridges is a much better signal to noise ratio which everyone will notice right away." That is actually a very complex statement, not completely correct and not completely incorrect, i... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Mahler, in my opinion, no, it is not possible to generalize about the different transduction mechanisms, as regards a pecking order of what gives best SQ. All MCs are certainly not better than all MMs, to address your specific point. | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Dover, I don’t think I can be wrong for asking why a “good LOMC cartridge” (whatever that is) would produce lowest groove noise. Because I’ve made no assertion. I just wanna know why. Of course I also think compliance, VTA, stylus shape, and almos... | |
| XLR Pinouts on Thorens TD1601 It's not "hot" and "cold". It's positive and negative. You correctly understand the problem, so the question is how to identify the positive phase signal (or the negative phase signal, for that matter). But it actually does not matter. The wors... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? The answer to Raul's OP question seems to be no, nobody knows which cartridge type is inherently "better". But most of us have an opinion. | |
| EAR 834P Deluxe with Dynavector 20 HX H output Cart. So don’t you think, if EAR make a great SUT, that the SUT built into the EAR is very likely to be excellent? Plus, it does away with the need for an extra set of RCA connections and an extra pair of external low capacitance RCA cables to connect a... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Please offer a mechanism to explain why a “good LOMC suppressed groove noise better than the others”, other than that’s your opinion. | |
| Phono preamp with multiple inputs?? Suggestions please!! Now let’s assume you have a cartridge that only produces 3 mV of signal voltage. The output from the MF phono would be 300mV. If you have an active linestage in the signal path, it is likely to add at least 8-10 db of gain. 10db means a 3-fold fur... | |
| Phono preamp with multiple inputs?? Suggestions please!! I just looked it up. The spec sheet say “5mV in gives 500mV out”, which is a voltage gain of 100, which translates to 40db. | |
| Phono preamp with multiple inputs?? Suggestions please!! The important number is not gain in mV, which only refers to some ideal setup, but phono gain in db. If MM phono gain is 40db or higher, and if the linestage adds 8-10db additional gain, and if the input sensitivity of the amplifier is 1mV or less... |
