| A challenge to the "measurement" camp DC resistance can be found at the low frequency point.AC resistance due to inductance is proportional to frequency.AC resistance due to capacitance is proportional to 1/frequencyAC resistance due to skin effect is proportional sqrt(frequency)Absen... | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? We are all told that cables make a difference. Absent knowing what cable or that there was a change, my experience in controlled environments says that is the cable is competent, there may not be a difference. Diminishing returns much quicker for ... | |
| A challenge to the "measurement" camp The joke is on you. You act with a maturity of a child. "lols" ... what are you 12? Grow up. andy2 OP1,195 posts07-08-2020 6:59pm The impedance frequency plot as requested by djones51, will reveal the critical composite of this data ... I am pre... | |
| digital or analog volume control? I have gold plated connectors that pass GHz signals cleanly. Gold plate does not roll off highs. | |
| A challenge to the "measurement" camp The problem speedbump, is that the controlled tests that have been done, and unfortunately there have not been a lot, are not very supportive of the theory there are easily noticeable differences between cables. My own work under contract in acous... | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? Atmasphere,How much advantage did you find by adding shielding of the XLR over just using a differential input w.r.t. noise?Interesting on the differential mode filter network. When you say it it seems "obvious", but certainly wasn't when the ques... | |
| Too good a post to waste I think this is the business model."But most of the scattered light - around 75% - is INVISIBLE and not amenable to absorption by ANY color, including green, turquoise, or even black."It seems this is an advertisement for a product that claims ... | |
| Too good a post to waste Do you just make these things up? Laser Diodes are highly monochromatic. Cheap diodes in a CD player will have all their spectrum +/- 3nm. These are not LEDs (which are still more monochromatic). The laser is not monochromatic but has an effecti... | |
| A challenge to the "measurement" camp speedbump6, with odd exception, I don't think anyone is doubting that personal preference is what matters or even suggesting otherwise, unless the discussion is about accuracy, then personal preference goes out the window.But if nothing of audible... | |
| A challenge to the "measurement" camp I will as soon as I dig myself out from all the brown stuff someone has been spreading.geoffkait 23,353 posts07-08-2020 11:05amThe signal in audio cables do not (rpt not) carry audio frequencies, they can carry RF frequencies. 😬 Nobody agrees wha... | |
| A challenge to the "measurement" camp @geoffkait ,No frequencies? So you are admitting that transmission line effects have 0 impact on audio? Nice! I knew you would come around eventually.>>>>>>Even more disturbing perhaps, the signal in audio systems has no frequen... | |
| Too good a post to waste Any evidence on a good quality audiophile transport that your "devices" result in a reduction in uncorrectable C2 errors. Heck, you could start with a basic computer CD ripper (1x speed of course). It is rather shocking you don't have this alread... | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? Maybe a point that needs to be made, you don't need an XLR to have a balanced input connection. You can use an RCA and still have a balanced input connection.BAT incorporates its “Flying RIAA Network” differential circuit here, which the company ... | |
| Too good a post to waste No data, very easily collected to support your hypothesis Mr. Pebbles. Very much noted yet again. Your silence is louder than any hypothesis you may preach. | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? kijanki,When you short a oscilloscope and probe to ground, you are creating a loop antenna and creating a differential signal which is not to say that common mode noise and/or common mode voltages are not a problem in measurement. That is why Pico... |
