| Importance of clocking Releasing a dirty stream to the D/A increases its processing No it doesn’t, latency has nothing to do with it and buffers are never “underutilized” because of back signaling. Perhaps example will help: Worker (DAC) has to place items on conve... | |
| Importance of clocking What about the clock accuracy releasing the buffer, then? It is internal DAC’s clock that is unaffected by any external activity (asynchronous). DAC uses this clock to take sample of the data from the buffer and convert it to voltage at exac... | |
| Importance of clocking Buffering is not a recipe for avoiding jitter. Yes, it is. With asynchronous USB data is delivered in packets (frames) to buffer at some time intervals, for instance 1ms - for instance 44 samples, DAC delivers each sample to D/A converter in... | |
| Meter for measuring cable capacitance It is “distributed capacitance” - you cannot measure it directly. What you measure is a combination of capacitance, inductance and resistance of the cable. I wouldn’t trust the meter, even when it displays sensible numbers. There might be more ... | |
| Can you tell the difference between a $200 and a $200,000 guitar? Inexpensive guitars built with plywood top, back and sides sound OK, but they won’t improve over time. Solid wood guitars open up and get louder with playing time. Vibration is causing some changes in solid wood. Solid top is the most important... | |
| Wifi ethernet jack recommendation I placed my entry fiber AT&T modem in pass-thru mode (to avoid double IP address) and use 2 piece TP-Link DECCO XE75 Mesh routers (with Ethernet outputs). Selecting 6E type router (tri-band) was important to me because there is a lot of traff... | |
| Can you tell the difference between a $200 and a $200,000 guitar? Presence - how responsive/resonant sound is in normal playing Projection - how much louder it gets when played hard Sustain - how long the note decays Separation - chord clarity, individual notes vs sound blob Tone - related to tone woods used So... | |
| how to fix a CD player Cleaning and lubricating helps, but I had once strange problem with Philips mechanism on Cambridge CD4SE player. Felt at the bottom of the puck that presses down CD after door is closed was worn, leaving gap and making CD to wobble. | |
| sending signal wireless from Mac to DAC- whats the best way ? My Mac Mini => Airport Express => Benchmark DAC3 via Toslink. Airport Express is no longer available, but you might find used or refurbish one. It limits transmission to 16/44.1 You can probably find some other Airplay receivers. I’ve heard ... | |
| Theoretically, How to Reduce Gain without Minimal Impact to Sound? I have Benchmark DAC and power amp. Benchmark recommends setting DAC's output high and amp's input low. That way more signal amplification is done in quiet environment (DAC). In addition it will be more immune to ambient electrical noise induce... | |
| Larry the Cable Guys @jea48 This cable looks good/solid. I would interleave "Line" and "Neutral" to reduce inductance further, but it might not be practical (difficult connectors assembly). In addition some inductance might produce filtering effect for high frequ... | |
| Larry the Cable Guys @jea48 What I said before about 4 wires having the same inductance as equivalent 1 wire would be true if 4 wires fit in the diameter of solid 1 wire - not possible because od added insulation. With larger overall diameter of multiple insulated ... | |
| Larry the Cable Guys So when you parallel four 20 gauge individually insulated wires, that gives an equivalent wire gauge of 14awg wire, (15 amps), is the net inductance the same for both conductors? Each of four individual wires will have higher inductance but con... | |
| Larry the Cable Guys @jea48 I believe that he is simply wrong. Thicker wire has lower inductance. Example: 2mm dia wire (gauge 12) has inductance of 345nH/ft, while 1mm dia wire (gauge18) has inductance of 388nH/ft (not much of a difference) As for capacitance ... | |
| Larry the Cable Guys Just one observation. Thicker wire has lower inductance. The reason for splinting wire into separate strands is skin effect. For copper skin depth at 20kHz is about 0.5mm * That would suggest keeping wires thinner that gauge 18. In plain st... |
