| Directionality of wire Quoted from AA: If you run the signal and return wires in the same direction you will end up with hot spots in the stage, normally at or close to the speakers, low image height and have a gaping hole in the middle of the stage...Keep in mind I am ... | |
| Directionality of wire Jim, re your question about Sean's post that you quoted, I looked at all of his posts in that thread, and many of those provided in it by others. As you alluded to, no specifics were presented, and so I have no idea as to what sort of "curious ph... | |
| Tekton Double Impacts The output impedance of my preamp in tube gain mode SE is 210 ohms. Is that considered high? No, not in itself. However the majority of tube preamps have a coupling capacitor in series with their outputs, which in some cases can cause their output... | |
| Tekton Double Impacts Porscheracer, some people have reported that using Rothwell attenuators has resulted in adverse sonic effects such as a reduction in perceived dynamics. Others have reported excellent results with them. I am in the latter group, having used the ... | |
| Tekton Double Impacts Cal3713, I agree with Charles that it seems evident that the 4 ohm DI impedance is a particularly benign one, with relatively little variation over the frequency range compared to most 4 ohm speakers, and little if any in the way of challenging ph... | |
| Directionality of wire Jea48 8-16-2017 herman, and or Al, (almarg) any thoughts? Jim (Jea48), thanks for providing the references, and the hypothesis about the possibility of the dielectric having directional properties to some degree, the dielectric being the medium th... | |
| Best fuses for under $50? Nonoise, to be sure it’s clear the caution I was expressing just above pertains not only to avoiding the possibility of blowing a fuse, but to avoiding the possibility of other damage to the equipment, or degradation of its long-term reliability, ... | |
| Best fuses for under $50? Kosst_Amojan 8-15-2017I tend to blow one once a week if I power it off and on again too fast while messing with connections. Georgehifi 8-15-2017This is what happens to a fuse over many switch on surges. Same fuse 5 different ageing periods, it ha... | |
| Shotgun with different cables Hi Bill (Wlutke),One way in which phase shift differences could occur between two speaker cables is from the interactions of their differing inductances with the impedance of the speaker. Another way is from differences in their propagation veloci... | |
| Shotgun with different cables I’m guessing there’s a theoretical stance that would have this kind of configuration a non-preferable solution (electrical properties gone "haywire," so to speak), in light of it being rarely used /talked about. But again, why really - what’s the ... | |
| Phono Stage voltage output to high ? The 7 volt number is the maximum output voltage **capability** of the phono stage. The actual voltage it will put out is determined by the phono cartridge, the gain of the phono stage, and the volume of the recording at any given instant. Everythi... | |
| Directionality of wire Geoffkait 8-13-2017Even if one wishes to refer to current as the "signal," since current is alternating we only need to worry about the current (signal) when it’s traveling toward the component or, in the case of speaker cables, when the current i... | |
| Soundtracks and Film scores, your favourites A minor clarification to the characteristically excellent post by Alex. The version of the "High Noon" theme he linked to, sung by Frankie Laine, while having been a hit recording, was not the version used in the film. The singer of that versio... | |
| 2 Channel Subwoofer connection If I understand the OP's situation, he can connect any active sub with high level (speaker level) inputs to the speaker terminals of his Jolida 202 and the Jolida will still recognize ONLY the load from his B&W 705s. I agree. The one qua... | |
| 2 Channel Subwoofer connection Regarding three-wire vs. four-wire connection of a sub to the outputs of an amplifier:In most stereo amplifiers (as opposed to monoblocks) the negative output terminals of the two channels are connected directly to the amp's circuit ground, and a... |
