| What is most important part of a system? Here is one of several prior threads in which this question was discussed:https://forum.audiogon.com/discussions/most-important-componentsFollowing is my answer as stated in that thread: Do not expect any consensus among the answers which will be ... | |
| Insane ground loop; anybody wanna try? Sounds good! Glad I was helpful.Regards,-- Al | |
| Why Single-Ended? Good to see you back here, Herman.Not sure that I agree with you, though, regarding: BTW despite what Ralph contends phono cartridges are NOT balanced as there is no ground, no ground pin connection, only 2 lines out. All sound sources are single ... | |
| Insane ground loop; anybody wanna try? Edwyun 2-22-2017 There can be a combination or cumulative effect of issues. +1. Specifically, it’s possible that there is nothing "wrong" with the AC wiring to the listening room, but it may have different characteristics than the more recent wiri... | |
| Why Single-Ended? DB, yes, it appears that the JC2 BP does not provide a tape loop or anything equivalent, so assuming you have more than one source I don’t see a way of connecting the KUBE into the system other than between the preamp and power amp.Kijanki, thanks... | |
| Why Single-Ended? +1 Charles.Regarding this comment in Kijanki’s post: In order to provide good common mode rejection two halves of FULLY balanced amp cannot be independent. Negative cross-feedback has to be used to equalize gains of each half and that might be far... | |
| Why Single-Ended? DBPHD, for the benefit of others who may respond I’ll mention that the manual for the JC2 BP states that it "uses a fully differential balanced circuit and its balanced outputs do not require or use phase inverters." Also, while as far as I can te... | |
| Insane ground loop; anybody wanna try? An experiment I'd suggest at this point that might prove to be informative would be to see if either Quicksilver amp produces hum when it and the preamp are connected and powered up as usual, but with the other Quicksilver amp disconnected from th... | |
| Why Single-Ended? In addition to the good points that have already been made, I would cite the following highly technical and abstruse factor: Traditions die hard :-)Related to that, I'd imagine that a factor in many cases is that designers tend to use approaches... | |
| Insane ground loop; anybody wanna try? the sub is connected to the XLRs via adapter and then by RCA cables. I wouldn’t be surprised if that turns out to be the key to the problem. While the post I made earlier today in this thread addresses a somewhat different situation, it provides w... | |
| Insane ground loop; anybody wanna try? Unplugging the sub has little effect ....Is the sub connected at speaker level (to the amps) or at line level (to the preamp)? And if the latter, is it connected to the preamp via XLRs, while the power amps are connected to the preamp via RCAs ... | |
| XLR cable signal ground wire question In many and I believe the majority of XLR cables the "ground wire" is the shield. But regardless of whether or not that is the case in a particular cable I would expect that any sonic effects the characteristics of the ground conductor may resul... | |
| Ancient AR Turntable with NO anti skate Regarding Stringreen’s advocacy for no anti-skating:As I mentioned earlier, my experience is comprised of cartridges having relatively high compliance. In recent times a Grace F9E, F9E Ruby, a Soundsmith-retipped F9E Ruby, a Grado Reference Sonata... | |
| XLR to RCA adaptor Thanks for the mention, JL35.Most XLR-to-RCA (and RCA-to-XLR) adapters short the inverted signal on XLR pin 3 to ground (XLR pin 1), although I believe Cardas can supply adapters on special order that leave pin 3 unconnected. Shorting XLR pin 3 to... | |
| 12" Tannoy Red. Worth anything? The label that can be seen in the second photo indicates that they are 15" drivers, not 12". Which are even more valuable. If the cones are original and in good shape my guess is that they are worth somewhere between $5K and $10K for the pair. Wit... |
