| Straight XLR vs XLR to RCA adapter I think you are referring to the possibility of using adapters at both ends of your RCA cable. That would definitely not be "doing it right," for several different reasons.I would emphasize, though, that the tradeoff between RCA and XLR interconne... | |
| Replacement for PS Audio Quintet Hi Howard,I and a number of other A'goners have been pleased with the Brickwall PW8R15AUD. It meets all of your criteria, except that I don't know how the effectiveness of its noise filtering compares with that of the Quintet. Also, it does not ha... | |
| Noise & Hum Rating Does the rating suggest that there will always be some hum and that this is normal? Does anyone know how this rating works at a practical level? Cary didn't have much of an explanation except to say that yes, some hum is normal.Your speakers appea... | |
| Are film capacitors directional? 3.3 and 3.9 ohms seem low enough to be unlikely to change the stated conclusions.Rodman, I'll make it a beer rather than a Coke. Next time you're in Connecticut!-- Al | |
| Are film capacitors directional? Hi Bryon,Yes, the Mundorf's are probably oriented correctly. The two wordings are consistent, although confusing. The lowest impedance in this context is the output impedance of the amplifier. So by orienting the outer foil of the capacitor toward... | |
| Does anyone use a different cable for the neg run? I may try grounding elsewhere than at the amp.No, don't do that. The return current from the speaker will want to find its way back to the circuit ground of the amp, and the consequences of that will not be good. If you connect the negative speake... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Ralph, thanks for the info about 100 ohms. I would not have suspected that such a low value would generally be effective.Regarding the effects of the transformer on the source impedance seen by the amplifier, though, I don't think that is the expl... | |
| Are film capacitors directional? Hi Bryon,I looked through the Fluke 115 literature. The one notable thing I found is that I think you should perform the measurement using the "AC Volts" mode, not the "AC Millivolts" mode. The meter's input is AC-coupled in the "AC Volts" mode, m... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Success, at long last. Outstanding! Although I guess we'll never really be able to be sure of exactly what was causing the problem, given the bizarre results of some of the experiments.The key thing with the XLR cable is that its capacitance has t... | |
| Coax to Optical Converters Anygood? I wasn't all that concerned with jitter as such, more with the quality of the signal not being compromised. Understanding that the more in the signal path the better the possibility for the signal quality to go awry. Assuming that bit errors do no... | |
| Are film capacitors directional? At the defense electronics company where I spent my career, in the forms that were used to report the results of investigations into test failures or other equipment problems there was a failure category entitled "operator error." That category wa... | |
| Are film capacitors directional? Hi Bryon,Are you using a setting for AC (not DC) volts? Not sure how you could sometimes be getting a negative number for AC volts.Also, charge that is stored in a capacitor can sometimes "bounce back" to some extent after a connection that has be... | |
| Big 2 channel Amp OR Smaller 6 channel and TRIamp? 02-18-12: EldartfordI have found that with a real music signal the peak voltage swing requirement for the higher frequency signal is only met by a power amp with substantially greater power rating than that based on equal power.No question about i... | |
| Coax to Optical Converters Anygood? Yes, Kbark, based on the claimed insensitivity to jitter I'd assume that the D/A conversion process is performed by this unit asynchronously to the clock on the incoming signal. Which will greatly reduce the importance of the quality of the conver... | |
| Are film capacitors directional? Hi Pehare,Thanks! I don't know the answer to your question, though, as I haven't ever used a RS DMM. FWIW I did use a RS FET-input (high input impedance) analog multimeter many years ago, and it seemed to work well, and lasted a long time.If the o... |
