| size of the driver Excellent insights from Drew, as usual. On the question that Bombaywalla raised about 3 db vs. 6 db, I believe that despite the apparent disparity you are both essentially correct. For a given drive voltage, the total radiated acoustical power wil... | |
| Fuses that matter. Hi Bryon,Sounds like you've done a good job of unearthing the kinds of explanations I'd expect to see offered for the supposed benefits of upgraded fuses. I suspect, however, that few if any of the offerings provide a quantitative perspective on t... | |
| Sunfire Signature... what is this? Looking at some rear panel photos that are available on the web, and at manuals that are available at the Sunfire website for what appear to be comparable later models, it appears that the 5A fuses (changed to 6A in later models) protect just the ... | |
| Fuses that matter. 04-28-12: GeoffkaitThere are obviously many reasons why someone might not get the expected results, including impaired hearing, lack of listening experience, faults somewhere in the system, failure to follow instructions, etc. Thus, negative resul... | |
| Why does better power = better sound? Hi Bryon,Assuming that "noise" is interpreted broadly, to include distortion and perhaps also DC offset, the only other things I can think of would be:1)Dynamic fluctuations in voltage resulting from resistance in the AC wiring, as current demands... | |
| Fuses that matter. 04-27-12: BryoncunninghamFor the amp (Pass XA30.5), I can't tell whether the fuse is pointed downstream or not. The fuse is held into the chassis by a cylindrical fuse housing that screws into the rear panel. Anyone know if there's a typical orien... | |
| Why does better power = better sound? Hi Lynne,What is relevant is the maximum amount of current that is demanded by the audio system. As long as a 15A rating would provide a reasonable amount of margin with respect to that demand (and I suspect that it will in your case, assuming tha... | |
| Who needs a MM cartridge type when we have MC? In reading your corrected statement, it seems you might be saying that a lower load resistance might be beneficial to the Stanton.Hi Lew,No, I was not implying that. My intent was simply to respond to your statement that "I have yet to read a clea... | |
| Who needs a MM cartridge type when we have MC? Correction to my previous post:Cartridge inductance and load capacitance (cable capacitance + the input capacitance of the phono stage) will interact to produce a high frequency resonant peak in frequency response, below the frequency at which rol... | |
| Who needs a MM cartridge type when we have MC? 04-26-12: LewmAlthough you [Raul] are not the first to suggest that the phono circuit downstream from the load resistor has something to do with the choice of load resistance, I have yet to read a clear explanation for why that would be, apart fro... | |
| Why does better power = better sound? Is intermodulation better understood as a fluctuation of voltage or a fluctuation of current? I understand that you can't change one without changing the other (Ohm's law), so maybe that question is meaningless. I would just like to have a better ... | |
| Why does better power = better sound? Hi Bryon,You're not there yet, but it is by no means hopeless :-)My statement that:The net voltage at any instant of time will be the NUMERICAL SUM of the individual amplitudes (voltages) of each frequency component at that instant of timehad noth... | |
| Why does better power = better sound? Hi Bryon,The effects I was describing do not necessarily relate to the DC outputs of the power supply at all. There are many possible pathways by which spurious frequency components riding on the incoming AC may couple into the signal path. To the... | |
| Why does better power = better sound? Hi Bruce,I have no particular knowledge of an audio-oriented conditioner that would handle multiple lines at the panel. But in any event I would expect that installing conditioners at the system end of the runs would be preferable, because they wo... | |
| Why does better power = better sound? Hi Bruce,If the lights that are dimming are not on the same 20A line as the system, then it suggests that a lot of the voltage drop is occurring in wiring that is upstream of that line, presumably on the input side of the panel. In which case addi... |
