| Focus on 24/192 Misguided?..... Al, On one hand he has whole chapter titled "192kHz considered harmful" describing harm that 192kHz can do to amplifiers and speakers to later say this about oversampling:"This means we can use low rate 44.1kHz or 48kHz audio with all the fidelity... | |
| Focus on 24/192 Misguided?..... Al, What sounds inconceivable to me is that 24/192 recording supposed to gain sound quality by downsampling it to 16/44 to be upsampled again, perhaps to the same 24/192. Am I reading it right? Is downsampling + upsampling somehow improving sound ... | |
| Focus on 24/192 Misguided?..... "nonsense! The Nyquist criteria applies to any signal that needs to be quantized. The Nyquist criteria only gives the minimum requirement; it does not say that one is forced to have only 2 samples per highest frequency."Yes, you can have more samp... | |
| Focus on 24/192 Misguided?..... I agree with Onhwy61 - article is a nonsense. First, motion that 16/44 is perfect if meets Nyquist criteria is first nonsense. Nyquist criteria applies only to continuous waves. Short high frequency bursts like cymbals will suffer the most of dist... | |
| Hi-end PC audio questions Speeddeacon, I chose do deliver data to Benchmark DAC1 wireless, using Airport Express optical output. Data is stored compressed in ALAC - the same format that is being used for transfer. Since data sent compressed in packets contains no timing an... | |
| Dropout when ripping CDs to wav or applelossless Cardiackid I use free MAX (MacMini with built in CD) with option "do not allow to skip". Sometimes it goes for a long time, reading the same sector over and over but ripped files never had dropouts (on 500+ CDs). I'm not sure how many times Itunes... | |
| jitter handling for bryston bda1 Jwin525, I have Benchmark DAC1 with Airport Express and sound is so clean that some might call it sterile. AE delivers, according to Stereophile review, respectable 258ps word jitter on optical output while DAC1 has huge jitter rejection. I like t... | |
| Impedance in headphones vs. speakers - confused Nadman12 Power delivered to headphones P=U^2/R, therefore in order to keep the same power/loudness, with higher impedance headphones, output voltage has to be also higher. Loudness becomes limited either by gain that is too low (tailored for commo... | |
| Dielectrics and such...?? Al, that's perhaps why some manufacturers use foam Teflon (including my Acoustic Zen Absolute ICs) - not only to lower dielectric constant but to reduce absorption (introducing air). As for driving 1.5nF - I'll take your word, having limited exper... | |
| Dielectrics and such...?? Al, I didn't notice the link you provided. I agree that 22nH per foot would be extremely low and we can take it out of the equation. So what else is there (other than resistance, inductance or dielectric) to consider? | |
| Dielectrics and such...?? Al, Yes part of the noise would be cancelled. Twisting just offers better cancellation. Reduction of inductance might be more important than reduction in resistance since xover inductor in series with the woofer has most likely around 0.08ohm limi... | |
| Dielectrics and such...?? 2chnlben , What is your objective? Dielectric properties of the tape (you could use Teflon tape) are secondary IMHO to fact that you defeat shielding of the cable achieved by twisting. Twisting two wires exposes them equaly to fields (noise) and s... | |
| AIFF vs Apple Lossless Ripping Thanks, Al. Your explanation makes perfect sense (as usual). Perhaps even Solid State Drives can really sound better, as Steve N. suspected, for the same reason of electrical noise being converted to jitter. I feel lucky with my setup where comput... | |
| Shielding components from EMI/RFI... Help please Al, I cannot hear any difference between different sources or cables with my jitter suppressing Benchmark DAC1. According to Benchmark and review measurements it provides very strong jitter reduction but few Audiogoners were able to detect sonic d... | |
| AIFF vs Apple Lossless Ripping I cannot hear any difference between ALAC and AIFF but it might be placebo effect since I know that hard disk ALAC or AIFF files have no timing and in reality it takes shorter to decompress than read larger file from hard drive. Data comes in pack... |
