| Why does better power = better sound? A further thought about power regenerators. My guess is that the root cause of the reduction in dynamics that they are sometimes reported to cause is simply that the 120VAC or whatever that they put out is different (and most likely lower) than th... | |
| Why does better power = better sound? Hi Bryon,Good comments by everyone above. My take is as follows, the bottom line of which is essentially what Elizabeth said:"Dirty power" will consist of some combination of harmonic distortion (i.e., frequency components that are at multiples of... | |
| Y connector from pre-out to powered sub and... More often than not, when a preamp provides two sets of RCA output jacks they are simply wired together just inside the rear panel, as opposed to being driven from separate output circuits. So chances are you would be driving all three destination... | |
| Balanced and Unbalanced outputs simultaneously I don't see any problems in this case, except that my instinct would be to avoid changing the position of the amp's input select switch while the amp is powered up.I'm sure Kijanki is speaking knowledgeably and accurately about the Benchmark. With... | |
| Amp design logic 04-23-12: River251I was really hoping for a discussion of the components in a $1000 amp vs those in a $50,000 amp, and how much they, vs the designer's intellectual property, contribute to the quality (and cost) difference. In other words, can I t... | |
| Amp design logic Kijanki, I not only admit it but I second it :-)Great line! Best regards,-- Al | |
| Amp design logic Many factors presumably contribute to that $50K sales price, many of them having been mentioned in the posts above. As someone experienced in electronic design (not for audio), one factor I would particularly emphasize is amortization of design an... | |
| VAC Owners:Outboard Phono Stage? Outstanding, Alon! And I must add that it's always a pleasure to read your witty posts.I take it that your preamp has both MM and LOMC phono stages. The manual seems to imply that the version of the preamp it is based on can optionally have one or... | |
| Focus on 24/192 Misguided?..... Excellent post by Kijanki. I agree completely.04-22-12: Bifwynne... do you know what the power bandwidth is on ARC amps, particularly the VS-115. Freq. response is approx. 100K, but I don't know if that is the same as power bandwidth.My understand... | |
| Who needs a MM cartridge type when we have MC? Frogman's post about harmonics is of course correct. For those of us like me who don't know that a fifth corresponds to a frequency ratio of 3:2, though, another way to express it is simply that the frequency of a harmonic is equal to the number o... | |
| Focus on 24/192 Misguided?..... 04-20-12: KijankiAl, I wonder if 24/192 contains any ultrasonic frequency at all. Why would they leave it preparing hi-rez files? Where this ultrasonic frequency comes from? Again, notion that 192kHz sampling is harmful is a little farfetched. Hi ... | |
| Focus on 24/192 Misguided?..... 04-20-12: BombaywallaAl, Kijanki: I *think* that I might know what the author is intending to say here: To do an A/B comparison, the author would like to level the playing field.... Does this make sense guys? Hi Bombaywalla,I think that what he is... | |
| Focus on 24/192 Misguided?..... Ok, I see what you are referring to. Note this statement:Oversampling is simple and clever. You may recall from my A Digital Media Primer for Geeks that high sampling rates provide a great deal more space between the highest frequency audio we car... | |
| Focus on 24/192 Misguided?..... Hi Kijanki,The only reference to downsampling + upsampling that I recall seeing was in the paragraph headed "clipping" in the lower third of the page, and in footnote 21. He was saying that by taking 192 kHz source material, downsampling it, and t... | |
| Focus on 24/192 Misguided?..... On the question of continuous vs. non-continuous waveforms, I think that part of the reason for the disagreement is that the word "continuous" is misleading in this context. No waveform is truly "continuous." Regardless of the nature of the wavefo... |
