| Dual Differential / Balanced? Al, I agree, that was invalid point - double DF doesn’t make much difference in most cases. As I stated in my older posts speaker’s impedance is mostly resistive and it is in series with back EMF reducing max possible DF to about 1. As long as amp... | |
| Dual Differential / Balanced? Al, I was looking at overall output impedance that speaker generated EMF sees, and that would be double. I also stated that fully balanced design is not only unnecessary to provide great noise rejection, but in fact might be worse than one achieva... | |
| Toslink VS coax VS other forms of Digital transfer Toslinik vs Coax. It is a system thing. Coax, because of faster transitions is less sensitive to system noise, but have some sensitivity to ambient noise and reflections within the cable (use <8" or >1.5m cable), as well as ground loops. ... | |
| Dual Differential / Balanced? @1 - I've never said that it doesn't. But it will remove cable noise by means of either balanced input in single ended amp or fully balanced amp. @2 - again, I did not say it removes even harmonics from the signal. It removes even harmonics produ... | |
| Dual Differential / Balanced? A single-ended amplifier with a balanced input and/or output is still a single-ended amplifier and does not offer all the advantages of a differential amplifier, which provides common mode rejection. This is not true, IMHO. Single ended ampli... | |
| Dual Differential / Balanced? Cleeds, yes, balanced operation is used in professional audio in form of balanced cables, balanced inputs etc. I’m all for it. I just don’t see how fully balanced amp can have better noise rejection than plain amp with balanced input. Instrumentat... | |
| Do supertweeters matter when we cant hear past 15,000 hz? Yes, it is. | |
| Do supertweeters matter when we cant hear past 15,000 hz? Tweeter will produce phase shift on its own without any analog filters. It is related to weight and stiffness of moving element. | |
| Dual Differential / Balanced? I don’t see benefits of that. Removal of even harmonics will make amp sound "colder" while doubled gain and power stages cost money. You can have much better unbalanced amp for the same price. | |
| Explanation for Class G amplifier heat differences between phono source & others? It shouldn't make any difference - gain stages take very little power while signal is "normalized" (by the volume pot) at the input of power stage. Class G amplifies like class AB but adjust (switches) power supply voltage according to signal leve... | |
| Dual Differential / Balanced? I can't see how fully balanced system can help with noise reduction. Common mode noise introduced at the input will go thru multiple stages of pre and power amp in both chains of balanced amp. Sum of gains in each chain can be different especially... | |
| Which should I do between Mac Mini or Auralic Mini WiFi makes anything on the computer side unimportant. Sound will be affected by the jitter on the receiving end. Use low jitter receiver or/and jitter rejecting DAC (or any DAC + Reclocker). Use power supply filtering/conditioner for receiver a... | |
| Do supertweeters matter when we cant hear past 15,000 hz? I remember reading about tests where people could distinguish music with bandwidth opened to 50kHz vs 20kHz. It is because our hearing operates in time domain more then frequency domain. Music is processed as wave and not as bunch of frequencies... | |
| Is This "Bi-Wiring"? Bi-wiring connects two sections of the speaker to amplifier using separate wires. It doesn't matter if it comes from two or 4 posts on amp side - it is the same output. There are few benefits of biwiring. Thinner wire can be used for tweeter an... | |
| Is This "Bi-Wiring"? I don't see anything wrong with it if you can engage both outputs at the same time. Assuming that both outputs are controlled by switches that has some resistance it might be even better to separate them like that. You won't dilute signal since ... |
