| Power Conditioning / Surge Protection I'm just tired of arguing, especially most of people don't follow the subject. I also don't understand some of your statements. Capacitor is charged only from the bottom of the ripple to next peak. Bigger ripple means longer charging time - ALW... | |
| Power Conditioning / Surge Protection We agree to disagree. | |
| Toslink Any possible difference in sound between Toslink cables is in amount of jitter they produce. Output LED diodes are slow. Transitions in Toslink are about 10x slower in comparison to coax. On the receiving end of the Toslink weaker light will re... | |
| Power Conditioning / Surge Protection Audio2design I did not say that ripple current gets higher. You argued that voltage on capacitor doesn't drop because charge time is higher. I only stated that when charge time gets higher - ripple is higher (capacitor is charged from the botto... | |
| Power Conditioning / Surge Protection Unless the amp is voltage clipping you have not made a good argument for true loss of dynamics though the loss would not be much different than line voltage variation. That resistance limits the peak current but extends the charge time so I your 1... | |
| Power Conditioning / Surge Protection Why do you keep talking about noise and voltage spikes?The problem is in narrow current spikes (pulses) charging capacitors that increase power losses on any impedance in series.During orchestra forte voltage on power supply caps drops. It is bec... | |
| Power Conditioning / Surge Protection Capacitors charge in narrow current spikes, but they cannot charge to the same full voltage when there is voltage drop on impedance in series.Perhaps spikes would be 1/12 less since we drop 10V of 120V. It doesn't change anything.I did not say m... | |
| Power Conditioning / Surge Protection audio2design, Let's assume that amp draws from mains 1A during music peaks. It will likely be drawn in spikes of amplitude reaching 10A. If filtering coil has 1 ohm resistance it will cause voltage drop of 10V equivalent to 20% of max power loss... | |
| Power Conditioning / Surge Protection You want to protect and to filter. The problem is that filtering places resistance in series that causes big voltage drops and kills dynamics. Most of power supplies take current from mains in short spike of huge amplitude (about 10 fold of aver... | |
| Optical Cable recommendations Very good inexpensive glass Toslink, I use:https://www.uniqueproductsonline.com/6ftgltodiauc.htmlIt comes in 3', 6', 12' and 25' lengths | |
| In-wall ethernet cable for streamer @jmphotography I agree - why not go for the best - it is not that expensive. The first computer I put together myself was 386 operating at 16MHz with 16MB of memory. It was a speed demon then. Things are changing fast! | |
| In-wall ethernet cable for streamer Why do you have to have it by the foot? Get the closest length of finished cables. Why not Cat 7 - many people reported improvement, some reported no difference, but so far I don't see anybody reporting decline. 100' of Cat 7 is only $20https:/... | |
| Optimal length(s) of a digital aes/bsu cable It depends on the output transition time . Without going into details, it is roughly transition time divided by 20. For typical 25ns transition it has to be longer than 1.25m. The problem is that transition time is unknown (and almost impossibl... | |
| Optimal length(s) of a digital aes/bsu cable Being balanced doesn’t change anything. Your cable might not be optimal length, but these calculations depend on many factors, like output transition time of the source, signal propagation speed in the cable etc. Also, this cable might be a perfec... | |
| Why so obsessed with bass? Both extension and dynamics are important, but I also noticed that my new speakers have better bass quality - very natural attack and decay. New speakers are three way with two 8" woofers in larger cabinet for bass, while the older ones were smal... |
