| Cable elevators It is possible that floor material (carpet, wood, vinyl) changes/adds to dielectric used in cable (that can affect the sound). Energy flows from amplifier to the speaker on the outside of the cable. I don't hear any difference but others might. | |
| Motherboard SDIF Output Or Soundcard Sound cards might reduce electrical noise, that can convert to time jitter of digital signal (especially with slow Toslink transitions). This jitter appears as added noise (loss of clarity). On the other hand Stereophile measurements of V90 show... | |
| $500 USB cable Digital coax cables are very different. In most cases D/A clock frequency is based on average frequency of the transfer while any time variations appear as jitter (noise in frequency domain). We can say that any S/Pdif cable (coax or Toslink) tran... | |
| $500 USB cable Perhaps we should understand what is happening to fully understand insanity of expensive USB cables. In asynchronous USB, computer transfers the data in frames at about 1kHz rate. USB DAC places the data in the buffer and responds with under/ov... | |
| $500 USB cable Chrisr, you're correct, in asynchronous USB timing makes no difference and the only thing affecting sound is injected (or radiated) noise by the cable. Digital S/Pdif cables are different - characteristic impedance mismatching causes reflections ... | |
| room space Assuming that your walls are 4m apart room will amplify 42.875Hz - (about the lowest sound of the bass guitar). 343/4/2=42.875where 343m/s is the speed of the sound in dry air, 4m is the distance between the walls and 2 - because sound has to g... | |
| Apple Airport Express to DAC Mini/Toslink cable might work better than adaptor+cable. I found that blinking yellow light on the AE is a sign that firmware should be updated. (It stopped after update). I'm not sure it changed anything since it worked fine before and after up... | |
| Guide for understanding wire gauge and resistance Just another take on the rule of thumb that wire diameter doubles for each 3 AWG unit decrease (i.e., #3 is twice the diameter of #6). #3 diameter is 0.2294" while #6 is 0.1620"Wire diameter doubles for each 6 AWG decrease. | |
| Anticables I bought used Acoustic Zen Absolute ICs that retail >$2k and found them better than $200 AQ King Cobra by small margin. Same neutral character, slightly faster transients, more refined (cleaner) with darker background, a little better imaging.... | |
| Guide for understanding wire gauge and resistance People usually think of speaker gauge when they calculate Damping Factor forgetting that speaker/driver resistance is in series with back EMF making best effective DF around 1.25 | |
| Guide for understanding wire gauge and resistance Read carefully again - RESISTANCE. As for impedance - it usually doesn't drop below couple of ohms making 10 miliohms irrelevant. | |
| Guide for understanding wire gauge and resistance Ptss, I understand you posted this in the context of the speaker cable resistance. Please take into consideration that most of the speaker impedance is resistive. 8 ohm speaker will have, most likely, resistance of 6 ohm. Your 10 mohms, in com... | |
| Apple Airport Express to DAC Found it:https://www.amazon.com/gp/product/B0002MQGRM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1and the cable:https://www.amazon.com/gp/product/B001D1A8KM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 | |
| Apple Airport Express to DAC Don't remember the brand - mini optical to Toslink, then 3' glass Toslink to DAC. | |
| Apple Airport Express to DAC I'm running AE (7.6.8) with no issues. I had Wi-Fi drops until I switched to 5GHz router (dual band). The only thing I can think of is, that either optical mini plug on the Toslink cable, or mini/Toslink adaptor (I use adaptor) have bad contact ... |
