| life span/failure rate of filter capacitors? @audioman58 IMO capacitor dry out powered or not. Unpowered capacitors are likely at lower temperature drying slower. Electrolyte tends to eat out dielectric (aluminum oxide) reducing breakdown voltage, while presence of the voltage rebuilds ... | |
| life span/failure rate of filter capacitors? Each 10degC temp increase shortens capacitor life by 2. It is simply drying out of electrolyte. Drier capacitors have higher ESR. At certain point current thru capacitors causes internal temperature increase. Temperature increases ESR and high... | |
| Perception and Watts: Doubling of power I found this equation in article about perceived loudness: L[%] = k^(1/3.5) where k is ratio of power. According to this 200W amp will sound 21.9% louder than 100W amp. 150W/100W ratio will make it 12.3% louder. Somehow it is easier for me to ... | |
| Can You Beat Simple? Real instruments have harmonic color, body, richness,vividness and full bodied tone There is now way to remove overtones/harmonics of instruments as long as amplifier/pre/DAC has adequate bandwidth. The only thing good gear can remove is color... | |
| Can You Beat Simple? That was my first impression when I bought Benchmark DAC. It sounded so clean - almost like some instruments were missing. I guess we got used to sound with a bit of distortion and/or jitter added noise that makes music sound more dynamic (like ... | |

| Out building for sound. The dream ver$e$ reality Don't forget about proper earth grounding: | |
| HDD to SSD migration and capacity? The only reason for more headroom is limited number of "writes" to SSD. Controller from time to time rotates data location to avoid any cell being written too many times. Disk with large overhead will last longer, but it applies to extreme cond... | |
| Dropouts when steaming with WiFi connection (Amazon Music). Change, if possible, your WiFi from 2.4GHz to 5GHz. Lower band has only 3 non-overlapping channels, since each channel is 3.5 channel wide. There is a lot of traffic on lower band and in my home microwave worked on one of the channels causing mu... | |
| Arcam CD23 worth saving? Ladder D/A converter are limited to about 18 bits because of components tolerance, while Delta-Sigma converters go only to about 20 bits, because of noise. Ring D/A converter was developed by DCS and licensed to Arcam. Instead of just one compone... | |
| Get out and listen! Good seats in many places (like Chicago Symphony) are reserved for subscription buyers only. In my suburban Chicago village we had nice auditorium (500 people) and great concerts. Last one was John Mayall with fantastic band, but the sound was w... | |
| To couple, or not to couple, that is the question I agree with Eric, it is complicated and floor does transfer sound. I tried to couple (spikes) and decouple (Vibrapods) and cannot say one way is better than another - just different sound. I moved recently from wooden floor/basement home to one... | |
| The character of analog and digital I had decent TT long time ago, but couldn’t stand pops and clicks. Perhaps it is possible to avoid them, but it is not my experience. Pops and clicks take me back to my room when I was already at the concert. As for R2R - layer to layer copying is... | |
| Grounding Question If equipment is designed with 3 prong plug (Class I Equipment) case is grounded protecting user from dangerous voltages. Grounding the case thru interconnect to another case is not only unsafe because of the limited current interconnect can carry... | |
| Pleasurably better, not measurably better I also like food analogy - imagine that you order famous Korean dish known for it salty and sour taste, but you cover it with sugar to your taste. Is it still original dish? When I offer green tea to my friends they put two teaspoons of sugar int... |
