| x-tronic 4000 soldering station Avs9, Hot air gun might be usefull for shrink tubing. I use standard large Wagner heat gun but smaller hot air gun or hot air pencil might be easier to use. If you plan to use different solders (different melting temp) then perhaps you need solder... | |
| x-tronic 4000 soldering station Avs9 - I'm not sure why you need station and not the soldering iron. Do you do any work with surface mount?180degC iron is wrong. Eutectic 63/37 solder (or solder paste) melts at 183degC and it would take forever to solder. Flux would clean oxidat... | |
| Hi-end PC audio questions Speeddeacon, AFAIK I tunes supports 192kHz while Apple TV 2 supports 24/96. Check out discussion here: http://www.stereophile.com/content/itunes-2496-wireless-apple-tv2-then-outboard-dacI don't have any equipment or knowledge of the format to veri... | |
| Focus on 24/192 Misguided?..... Thank you Al. If there are any harmonics within 50kHz amplifiers should be still linear (modulation can only happen on nonlinear element). Any problem would already show with vinyl gear that has similar bandwidth. I don't really see any source of ... | |
| Focus on 24/192 Misguided?..... Bombaywalla, Bifwynne - No, I don't know the numbers, but suspect it is at about a half or less. Delivering full power at high frequencies is not really important since very little power goes to tweeter. In my Rowland 102 max power at high frequen... | |
| Focus on 24/192 Misguided?..... Bombaywalla, Making amplifiers cutoff frequency at 20kHz means that phase shift at this frequency will be in order of 45 degree causing bad summing of harmonics. My small Rowland 102 amp has 65kHz bandwidth with about 22deg phase shift at 20kHz. N... | |
| Focus on 24/192 Misguided?..... Al, My DAC and perhaps a lot of them cuts at 45kHz. AFAIK vinyl recordings also extend to about 50kHz. It is considered to be an advantage of vinyl. | |
| Focus on 24/192 Misguided?..... Audiofreak32, I enjoy my system all the time. ALAC is lossless while wireless transmission is bit perfect. Benchmark is as clean as it gets on the verge of being sterile but it fits perfectly with my warm sounding Hyperion HPS-938 speakers. In add... | |
| Focus on 24/192 Misguided?..... Al, 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. Do we have any studi... | |
| 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... |
