| Should the power be off every time changing cables? To clarify, component off or system off? If the component (for example Pre to Amp), then the Pre or the Amp or Both? @david_ten Hi David,In the case of RCA line-level interconnections, at least, and particularly if the components involved are ... | |
| Should the power be off every time changing cables? Don’t ever do that with RCA cables. It may be ok with XLR cables, but personally I wouldn’t risk it with those either.RCA cables make the signal connection before the ground connection upon insertion, and break the ground connection before the sig... | |
| Preamp connection to multiple powered subwoofers kalali, did I not already say don't overthink it? And then you go and compliment and start paying attention to the world's greatest offender in overthinking it? Now it appears you have overthought things to the point you've concluded that what w... | |
| Is grounding with RCA is safe? I am thinking about a DIY passive grounding box, which is a wooden box with different minerals inside. I think it does not take much time to turn what I am having now into a DIY passive grounding box. Not to take sound quality into consideratio... | |
| Preamp connection to multiple powered subwoofers @kalali,The impedance ("capacitive reactance") of a 2.2 uF cap at 20 Hz is 3619 ohms! The impedance of a 3.3 uF cap at 20 Hz is 2413 ohms.The specified 600 ohm output impedance is presumably at 1000 Hz or thereabouts, and mainly represents the ou... | |
| Main DC or AC true removal of Electrical interference Other option is to bypass all together and get a pure sine wave converter and Sealed AGM batteries for my music system??? Like a solar array but just for music. Anybody done this? It sounds perfect in theory by bypassing everything your power line... | |
| Need a line stage preamp When it comes to line-level analog interconnections between source components and preamps issues relating to impedance compatibility are no different than when it comes to analog interconnections between preamps and power amps.To assure impedance ... | |
| Need a line stage preamp @last_lemming Note that I was referring to the 10K **input impedance** of the Schiit models that were mentioned, and the possible incompatibility that might cause with the output impedances of **source components** (especially tube-based source co... | |
| Need a line stage preamp Keep in mind that the input impedance of the Freya S is only 10K, which is too low to be optimal with many tube-based source components.Also, as Coach pointed out the two versions of the Saga do not provide any gain, while also having a 10K input ... | |
| Preamp connection to multiple powered subwoofers I can see how I could use a couple of splitters off the second pair of RCA outputs and run the four (powered) subs in mono. Makes sense. And perhaps I’m overthinking the impedance matching side of it but I was just concerned about what the preamp ... | |
| Difference in sound between copper and silver digital cables? ... could it be possible that the impedance of the RCA only has to be greater than 50,75,101 ohms? @williewonka Hi Steve,Thanks for providing the additional background. But no, for accurate minimally distorted transmission of digital waveforms, t... | |
| Aric Audio? First Watt? PrimaLuna? I’ll add to my previous comments that Iike Coachpoconnor I too own and am delighted with an XA25, and although I use it with speakers that are much more sensitive than yours I too believe that it would be a fine match for your speakers. Stereophil... | |
| Difference in sound between copper and silver digital cables? Williewonka 1-3-2020The geometry of the cables is an advance Helix design, so that probably made a significant contribution to the performance of the cable. Steve, I always have great respect for the very extensive work you’ve done with cables ov... | |
| Need a line stage preamp If you don't require the balance control or the tape loop your LS11 provides, you may want to consider the following very law-abiding model, costing $450 new: http://www.divertech.com/asllineone.html Spec-wise it appears to be a fine match for y... | |
| Polarity Conundrum Yes, it’s that simple, assuming two things:1) Most importantly, this assumes that the speakers are passive, e.g. they do not include built-in amplification, and that powered subwoofers are not connected to the amp outputs. In either of those cases... |
