| More Grounding Questions Will ground loops degrade sound quality even though it does not hum?In addition to producing hum, ground loops can also result in high frequency noise and buzz, by coupling harmonic distortion components and/or noise that is typically present on t... | |
| Can temperature fluctuations affect audio gear? Magfan & Bigbucks, I'll say first that thermodynamics was definitely not one of the shining successes among the courses I took in college, but pending further info from Magfan's PhD friend I believe that Bigbucks is correct.Magfan: In SS, for ... | |
| Cables for high efficiency speakers? If not a single conductor then must go with Alternative II?No, I was not implying that. The calculations for cables that employ multiple separately insulated conductors just become a bit more complex, as I described.BTW, cables that employ that ty... | |
| Do you listen alone or with guest s 12-03-10: TvadHarvey has an open invitation at our house. He sometimes joins me.Isn't that right, Harvey?Harvey says yes.I'll bet that Harvey helped you to improve the transparency of your system.Best regards,Al :-) | |
| Cables for high efficiency speakers? How do you evaluate/measure skin effect?It would take me several pages to go through the detailed calculations, but this is a summary of the methodology:Alternative I:A)If the cable consists of a single conductor for each leg (plus and minus):1)St... | |
| Two NAD 2200 bridged amps w/6 ohm speakers - OK? As shown on the last page of this datasheet the 2200 is rated to deliver considerable short-term power into a 4 ohm load (which would be seen as 2 ohms) when in bridged mode. It is not rated to deliver continuous power into a 4 ohm load when in br... | |
| Do you listen alone or with guest s About half the time with my wife and half the time alone. I second Jgiacalo's eloquent comment, while also agreeing with the other comments that it is easier to concentrate when alone.Regards,-- Al | |
| Cables for high efficiency speakers? I would not use a thick gauge wire because a high efficiency speaker will react adversely to skin effect. The degree to which skin effect may be audibly significant is controversial and highly debatable. I don't want to get into a debate on that i... | |
| Can temperature fluctuations affect audio gear? I agree with Elizabeth. I wouldn't worry about the possibility of damage, if that was the point to your question. I would add, though, that from a technical standpoint it does seem conceivable to me that a 25 or 30 degreeF difference in ambient te... | |
| Cables for high efficiency speakers? I agree with Stan. I can't envision any reason why high efficiency speakers as a class would be best served by any particular kind of cable. Higher efficiency = less current flowing in the speaker wires, which (assuming everything else is equal) s... | |
| A history question about planar drivers The search returns 9 results if you change the setting in the "search years" drop-down box from the default of "1976 to present" to "1790 to present." The default setting returns 7 results, as you found.Regards,-- Al | |
| A history question about planar drivers 12-02-10: MlsstlIn reference to patents, the devil is certainly in the details. I believe that patent law is one of the relatively few official subspecialties in law practice; it requires special authorization to practice before the Patent Office.... | |
| Need help picking subwoofer cables interconnects I'm swapping out the S300 with a Belles 150A v2 Reference, which is 100k input impedance, but that would still result in a total of just over 9k -- still too low compared to the recommended 20k+ load of the Symphonies. Then again, I've been using ... | |
| Need help picking subwoofer cables interconnects Important follow-up to my previous post:I just noticed that the S300 appears to be a fully balanced amp, and its manual therefore has strong cautions against connecting any of its speaker output terminals to ground. If the subs have 3-prong power ... | |
| Need help picking subwoofer cables interconnects Is the equipment list in your system description up to date? If so, there is a larger issue that is present, which makes Foster_9's suggestion of using speaker level connections particularly appropriate.Preamps that have two sets of outputs usuall... |
