| Does the Quality of the USB cable matter? The one way in which I can envision a USB cable connecting an external hard drive to a computer could make an audible difference is by affecting the amount of RFI that may be radiated from the cable into the audio system. Like most digital signals... | |
| When Bi-amping is there change in sensitivity Manitunc, I'm not sure I understand what you are not understanding. Energy is proportional to power (factored by time). Power is proportional to voltage times current. As you undoubtedly realize, in a passive biamp configuration there is no connec... | |
| How much can be measured -- and how much cannot? 03-19-12: AhendlerActually I have never found measurements to help me in any audio decision to by a certain product. Measurements are helpful in the design process but do not tell you anything how a component will sound. Let me supplement my previ... | |
| USB to External Hardrive does USB cable matter? Al, can you recommend a shielded 50 foot Cat 6 cable?Hi Ozzy,I think that what would be most ideal is a cable having both an individual shield around each twisted pair of wires that are within the cable, and an overall shield surrounding all of th... | |

| cable burning Hi Kijanki,Your comments are well founded, IMO, and I completely agree with them. I have no particular knowledge of the specific 1 MHz corner frequency, but I assume your information about that is good.There is a "network" near both ends of the ca... | |
| When Bi-amping is there change in sensitivity 03-19-12: ManituncIn a passive bi-amp situation, where a preamp is feeding two power amps and the signal from those power amps are feeding a bi-ampable speaker where the connection between the bass and midrange/treble is removed, where does the ex... | |
| USB to External Hardrive does USB cable matter? I second Kijanki's comments, especially given that the USB cable is a long distance away from the audio system, which most likely eliminates the possibility that rfi could radiate from the cable into the system.If your ethernet cable is the unshie... | |
| How much can be measured -- and how much cannot? I second Mapman's comments. As I see it the main usefulness of measurements, and also specifications, is that they allow one to identify and RULE OUT candidates for purchase that would be poor matches to either the rest of the system (e.g., impeda... | |
| When Bi-amping is there change in sensitivity Thanks, Frogman.Is it not true that of great importance is each amp's input sensitivity? And is there a correlation between an amp's power rating and it's input sensitivity as Al suggests? That has not been my experience. In referring to sensitivi... | |
| cable burning Here is the manufacturer's description of the rationale for the passive components in their cables. From a qualitative (non-quantitative) standpoint pretty much everything in their statement strikes me as making sense. The quantitative significanc... | |
| Do you believe in Magic? Thanks, Bryon, for the perceptive and instructive analysis, and for the compliment.Yes, "informed sense" is a better term than "common sense" for what I was trying to express. It comes down to having a good instinct for where to draw the line sepa... | |
| When Bi-amping is there change in sensitivity I'm not sure that the level control on the tube amp will be able to do the job. My suspicion would be that even with it set to its maximum setting the 500W amp would still have a higher gain. If so, you would still have to provide a means of reduc... | |
| When Bi-amping is there change in sensitivity No, the sensitivities will not change. You will have to provide some means of compensating for the difference in the gain of the two amps. Otherwise a tonal imbalance will result.Most likely the 500W amp will have higher gain than the 80W amp, so ... | |
| advice on powering my martin logan vistas No, don't use the amp in bridged mode with the Vista. A bridged amp "sees" a load impedance equal to the impedance of the speaker divided by 2. So it would see the Vista's nominal 4 ohm impedance as 2 ohms, and its 1.2 ohm impedance at 20 kHz as 0... |
