| 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... | |
| music file storage/playback suggestions please I use Itunes on the Mac. I created "Smart Playlists" by genres (for instance: "Match music for the following rule: Genre is Rock"). After that it displays much nicer - a whole page of thumbnails of CDs. Much easier to use. The only drawback is... | |
| Wireless or wired? ronboco, I use WiFi and can see two possible problems. One is interference. There is a dozen of channels at 2.4GHz, but you can only have three non-overlapping and I had dropouts. I switched to 5GHz and it is fine now. The other problem is del... | |
| Amp or DAC? cd45123, I had class D amp and currently have AHB2. Both have excellent bass control but AHB2 has a little bit better extension. I cannot explain it, since on paper it is only few Hz difference (5Hz vs 0.1Hz), but it is audible (same source, spe... | |
| What's your definition of an audiophile? Audiophile is a man who is afraid that after his death his wife will sells audio equipment for as much as he told her he paid for it. | |
| Amp or DAC? If there is a difference between the 75w and 150w per channel amp can I narrow the gap or even exceed the 150w amp by using a better DAC?You assume that 150W would sound better, but it might be the other way around, since you pay for larger power ... |
