| “Black background” — What really contributes to this phenomenon? I have to admit I’m a bit bemused with focus on noise from the mains... I’m not saying it’s not a problem, it’s just never been a problem for me... can someone explain what mains noise sounds like in a way I might understand, like bangs, pops, thu... | |
| “Black background” — What really contributes to this phenomenon? Proof positive of all this is in my room. The room noise is very low and so everyone easily hears the system noise.That was my point... the system noise doesn't need audible either, it's the components that are creating it. | |
| “Black background” — What really contributes to this phenomenon? I agree that eliminating noise from the system will achieve that 'black background' that many are looking for. I also think it's helpful to put noise into two different categories, one being interference and the other being random noise.Interferen... | |
| Why wont speaker companies publish their measurements? Shame... this could have been a good discussion instead of a pissing contest. | |
| Why wont speaker companies publish their measurements? If your talking about the in depth detail that Stereophile go into when they measure speakers, it's because most don't have that kind of expensive measuring equipment/room, just the basics.But there are plenty of test facilities around... I can re... | |
| Why wont speaker companies publish their measurements? I get that measurements aren't everything but they're a useful guide if you're looking for something specific, particularly as it's not that easy to walk into a showroom at the moment. What measurements beyond the standard power, efficiency, physi... | |
| Best sounding resistors I think it's worth pointing out that tantalum is a conflict mineral, something I didn't realise until a few years ago which led me to stop using the capacitors. | |
| Best sounding resistors If money is no object then bulk foil are pretty unbeatable - however are probably not worth the expense across the board. The greatest benefit is the low temperature coefficient so worth it when they'll be dissipating some heat or near another com... | |
| Ok to adjust balance to achieve center vocal image? Might be worth checking whether the stereo image moves when you adjust the volume. If your volume control is a log potentiometer the left/right matching is awful at lower settings. | |
| Differential Balanced Sound Quality I apologize if you see this as being patronized, that was not my intent!Cool... no problem.Take a look at the first hit (this is an images search). The first image shows both what you’ve described **and** what I described in the same image, the la... | |
| Differential Balanced Sound Quality There's no such thing as 'cold signal'.The term is commonly used both in text books and the professional recording environment as shorthand for the inverted signal in a balanced pair... It doesn't confuse me and I don't need to be patronised.If yo... | |
| Differential Balanced Sound Quality @atmasphere Happy to try to explain, it’s a shame that there’s no way of posting a picture...So if I start with a conventional amplifier block with an inverting and non-inverting input and a single output. A single ended amplifier input might be a... | |
| Differential Balanced Sound Quality The bit that a lot of people are unaware of is that balanced inputs are actually noisier than single ended (RCAs etc.) in that they utilise relatively high value resistors that introduce their own (johnson) noise into the signal.This statement is ... | |
| Differential Balanced Sound Quality Balanced connections are all about eliminating external noise that gets picked up in cables etc. They also pretty much deal with ground loops as well. So if either of those things are a problem in your system then using balanced connections is eff... | |
| Frequency Response The positive for your situation is that the wavelength of the problem frequency is around 1m and to effectively treat with an absorber the rule of thumb is 1/4 wavelength thickness of material so 25cm or 10" which is pretty do-able. That might sou... |
