| Replace volume pot Most likely it won't do anything for you because pot's are used as dividers and not resistors. They select value around 20k - 100k because smaller values tend to load previous stage while unnecessarily large pots are prone to noise pickup and migh... | |
| CAP QUESTION I assume you're talking about electrolytic caps. If it is power supply cap then it might explode. Reverse polarity causes electrochemical reduction of dielectric leading to short that heats up electrolyte, expanding and possibly exploding. | |
| iTunes dropping album artwork Puerto, You can open properties by right clicking and selecting "Get Info". You can do that to one song or more if you mark them. Sometimes only one song has artwork. I don't know why, perhaps this song was highlighted/selected when I was dragging... | |
| iTunes dropping album artwork I had this problem when one song was selected. During playback artwork was shown only for one song. I fixed it by marking all songs and pasting artwork in properties. | |
| How Do Digital Amplifiers Clip? Yes, soft clipping is built into Icepower amps. | |
| Re Biasing a SS Amp? In my opinion it will make it worse. It is called overbiasing. There is optimal amount of bias for any class AB amplifier. Increasing bias makes partial operation in class A but is increasing window of increased gain caused by the fact that two, i... | |
| Why do digital coax cables matter? Sure, but I would sell that system and get one that meets the specs so I dont have to try to find a wacked-out cable that matches it.How user can possibly know that wire or system meets the spects? I prefer to choose cable for the system and not t... | |
| Why do digital coax cables matter? Steve, What you describe is general quality of the cable and not performance of the cable in particular system. Characteristic impedance different than 75 ohm can be very good, as Al mentioned, if it is better match for given system. Same for slow... | |
| Why do digital coax cables matter? Robertsong, typical CDP used as a transport outputs digital S/Pdif signal with about 25ns edge transitions. Speed of signal in the wire depends on the dielectric but we can assume about 5ns/m. Very start of transition (knee) travels thru cable and... | |
| Amplifier Capacitance Ralph, that's very interesting. I just looked at Jeff Rowland Capri preamp - the upper limit is 350kHz but bottom is only 10Hz. It could be direct coupled with servo (integrator) in the feedback set to 10Hz. In any case, he did it for a reason. My... | |
| Watts up with that? And no, you can't remove imaginary components of an impedance curve by physicaly moving your physicaly.I'm sure I can. For instance when I rotate my incandescent bulb 90 degree counter-clockwise they become dim but when I turn them 90 degree clock... | |
| Watts up with that? Speakers are only 5% efficient, so that means the majority of the impedance is imaginary in nature and does not do work.Everybody knows that speakers play on one wall better than on another. It is because 90 degree rotation eliminates imaginary (p... | |
| This may be a dumb question... You need program that can translate formats, like (free) MAX. MAX is ripping program for OSX but it translates any format to any format as well. | |
| Amplifier Capacitance why not increase the voltage rating, to improve the longevity, ESR, and inductance characteristics instead?The price of higher voltage, low ESR, low inductance caps is perhaps too high. I checked once site that sells Hypex class D kits. Power supp... | |
| Amplifier Capacitance Bombaywalla, Yes, power supply should be clean but I was talking about modulation of power supply voltage by varying load that amplifier presents. Low frequency will definitely do it (biggest current) and high frequency will do it as well (inducta... |
