| Higher Impedance MC Carts on Transimpedance Stages? Hagtech, You wrote, "There is no real contribution from phonostage, since it appears as a dead short, we are talking transimpedance, right?" I learned my audio electronics from a few good books and from reading what others say on the internet, al... | |
| Same Dance but New Step Sounds like the grinding sound had nothing to do with alignment. What was the problem as identified by SS? | |
| SUT help This is very simple, besides the fact that you don't need a SUT. You can use any SUT with a 1:10 step up ratio. That means the signal voltage will be increased 10-fold, to 4mV with either of the two cartridges in question. That is easily enough ... | |
| Hagerman Piccolo Zero: New transimpedance head amp "Head amp" usually refers to any outboard device that adds gain but not RIAA correction to the phono signal, ahead of the phono stage. These days, a head amp can be current driven or voltage driven. The Piccolo comes either way, I think. | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? Bipolar transistor for balanced circuit; FET for single-ended circuit. Either used in a cascode topology with a tube "on top", gives very high gain with very low noise. | |
| 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. |
