| MC Step Up Math With the dynamic nature of the impedance characteristic, would it not make sense to pick a "flattest" segment of the curve to operate on. The X Axis turns ratio variable can be converted to effective load, then picking a impedance load such that i... | |
| Why not these cables for my TT After looking at the description and specifications of the cable, I see no reason not to give it a try. You may need a separate ground wire, of course, to prevent hum. Plain old 18 or 20 or 22 gauge hookup wire should be fine for that purpose.If y... | |
| MC Step Up Math To answer your questions just above, there is substantial anecdotal/empirical evidence that if load impedance is numerically low enough to approach the value of a LOMC's specified impedance, dynamics, resolution, and transient impact will usually ... | |
| MC Step Up Math Re Lew's point about the possibility of adding a resistor if necessary, I'll add that the parallel combination of two resistances corresponds to an overall resistance equal to the product (multiplication) of the two values divided by their sum. So... | |
| MC Step Up Math Effective load close to or less than cart impedance is what I think you mean is a problem...or by heavily loaded. Yes. And I'm also saying that having a load impedance that is heavy enough (numerically low enough) to approach the impedance of the ... | |
| MC Step Up Math What is effective Load. He is taking 47,000/(turnsratio^2). What does that tell you, what is that calculation? A transformer transforms impedance in proportion to the square of the turns ratio. So the load impedance seen by the cartridge correspo... | |
| MC Step Up Math As the load impedance seen by the cartridge becomes higher in relation to the cartridge's internal impedance, the difference between the two calculations (i.e., the calculations with and without application of equation*) becomes progressively smal... | |
| MC Step Up Math I haven't taken the time to read the references you provided, but I believe I can shed some light on the discrepancy you cited. First, Vout: Voltage output at secondary side of trannyIn the given context "secondary" should be "primary." Vout is be... | |
| XLR or RCA? This is one of the rare occasions when I must very respectfully disagree with my learned A'gon colleague and friend Jmcgrogan2, although the opinion he expresses is shared by many audiophiles.Elegal 02-17-14I then read that xlr cables only provide... | |
| differential versus common-mode noise? Whether digital (or other) noise is common mode or differential has to do with each of the places it gets to, not with where it originates.If it appears equally on two associated conductors, to a close approximation, then it is common mode at that... | |
| New to headphone amps --- I'm wondering ..... Hmmm, I just noticed that per this spec sheet the 97 db/V sensitivity spec shown at the AKG website is incorrect, big-time!Per the spec sheet, the figure is 97 db/1mw, which seems a lot more sensible. So 99 db would be produced in response to an i... | |
| New to headphone amps --- I'm wondering ..... Mechans, as Mulveling indicated my calculations are consistent with the published specs, shown near the bottom of this page. As he points out, though, it certainly seems possible that the max power handling number reflects how much power the headp... | |
| TT Power Cord Good points by Lew and Moonglum, IMO.Also, a common sense point that seems worth mentioning is that the turntable's power cord should be kept as far away as possible from the phono cable, to minimize coupling of EMI or RFI from the power cord to t... | |
| New to headphone amps --- I'm wondering ..... Lots of good points have been made above. I would particularly emphasize three of them, and add a fourth.1)02-10-14: DoggiehowserThe relative amount of power needed to drive cans (even something as difficult as a pair of Hifiman HE6) is a mere pit... | |
| Bolero:why can't my system reproduce snare well? However, last night, I was listening to Bolero, and the snare sounded terrible.... These speakers sound good on bass, but also seem to be lacking on cymbals as well.... All: can you please recommend a good reference LP? I currently do not have a c... |
