| Do caps deteriorate with time even if an amp is not being used? Electrolytic caps loose rated breakdown voltage and also dry out. They loose rated breakdown voltage because electrolyte "eats out" dielectric - aluminum oxide (presence of voltage rebuilds this layer). They dry out - especially when hot. Each ... | |
| They Almost Never Quote A Price , Why? It is pretty much like restaurant with no prices on the menu - if you have to ask you cannot afford it. | |

| Bi-wires links for speakers ? Highs - sounded more extended. First time I installed them in Paradigm Studio/60 v2 speakers that came with stock bent plate jumpers. Now I have them with Hyperion HPS-938 that came with long insulated wire jumpers. These speakers are three way wi... | |
| Bi-wires links for speakers ? itzhak1969, I use Audioquest 4" jumpers. They're made of high purity AQ copper and come either silver or gold plated. I use gold plated version. Big improvement over stock thin-plate links.https://www.amazon.com/SET-4-GOLD-BIWIRE-JUMPERS/dp/B00... | |
| Problem with CD Baby cds perhaps laser lens needs cleaning? | |
| Voltage source vs. current source amplifiers Ideal voltage source provides voltage that is independent of the load.Power delivered will be inversely proportional to load impedance.Ideal current source provides current that is independent of the load.Power delivered will be proportional to lo... | |
| 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. |
