| Why does better power = better sound? 3 and 4 is same as 1 and 2 - greater dynamic range requires good current delivery and low noise. Instruments won't have natural timbre thru noisy gear that compresses dynamics. 5 - Imaging is related to noise as well but also to crosstalk, often t... | |
| Balanced and Unbalanced outputs simultaneously Dougwhitesell, This is excerpt from Steven Stone Benchmark DAC1 October 2007 review in "Enjoy the Music"."Since it has both XLR balanced and RCA single-ended outputs, the DAC1 can be hooked up to a stereo amp through the XLR connections and to a s... | |
| Amp design logic Stanwal, my friend was planning to do the same with amplifier he designed. Unfortunately this amplifier had tendency to oscillate in certain setups. I told him that it would be financial suicide if his amp will start damaging customers' speakers. ... | |
| Focus on 24/192 Misguided?..... Bifwynne, LOL | |
| Balanced and Unbalanced outputs simultaneously Dougwhitesell, I have Benchmark DAC1 and don't know of any switches. From what I can see signal splits after D/A chip and goes to separate op-amps for XLR and RCA outputs. RCA outputs can be calibrated with multiturn trimpots while XLR outputs are... | |
| Amp design logic Al, you're right of course, but you have to admit that my animal joke fits to expensive cable trade. | |
| Amp design logic When I see people buying and selling $50k gear it reminds me this guy who successfully sold dog for $50k by trading it for two cats $25k each. | |
| Squeezebox touch-itunes or not? Jamo1, I use Airport Express but idea is the same - data wirelessly transfered in packets between transmitter (computer) and receiver (AE, Squeezebox etc). What does it mean? It means that data is transferred instead of music. It is important diff... | |
| 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. |
