Linear Power Supply with audio-grade Caps is any better than …
2022年1月30日 · I said the capacitors he’s using in his LPS should not provide better DC output than the same parameter capacitors! I challenged him to show the oscilioscope of his LPS DC output measurement but he tried to avoid. I don’t see …
Crossover capacitors - Audioholics Home Theater Forums
2009年6月4日 · You should be highly skeptical about $100 capacitors! The type of capacitors I prefer for new crossovers are the inexpensive metalized polypropylene (MPP) type sold by PartsExpress. For example, a Dayton 10 µF cap costs $4.12 and a Bennic costs $4.50. Don’t pay extra for the Dayton ±1% MPP caps unless their standard ±5% ones are out of stock.

Older amp, upgrading capacitors - Audioholics Home Theater …
2019年7月20日 · The audio brands needed a local China source for electrolytic capacitors but unfortunately the China suppliers had not yet mastered the design/production process for electrolytic capacitors. The previously built audio components largely from Japan in the 70s' used a better grade of electrolytic capacitors.
Capacitors crossover replacement - Audioholics Home Theater …
2018年10月6日 · 400v capacitors will be physically larger, and will cost more. Those voltages are ratings at which they've been tested to avoid failure. They indicate nothing about possible differences in sound quality. Both 250 and 400 are voltages higher than what should occur in audio crossovers.
Re-capping older amplifiers | Audioholics Home Theater Forums
2012年9月19日 · Capacitors, especially the soda can sized things in older Levinson amps (and Thresholds, Krell, etc), do indeed age and eventually need replacement. Both environmental and usage factors can affect aging, and it's always been my suspicion that older high-end amps have a usage model that these high-power capacitors weren't designed for.
Is it worth upgrading crossovers - Audioholics Home Theater Forums
2022年12月14日 · AVRs are multi-channel audio receivers, that are also digital computers dedicated to operating home audio from simple stereo set ups to multi-channel audio from digital movies. Sub-woofers, controlled by the digital processing system within the AVR, allowed a completely different and more effective way to integrate sub-woofer(s) into a speaker ...
Cap 'break in' | Audioholics Home Theater Forums
2017年5月2日 · Coupling capacitors for the most do not have such a difference a.c.wise - they are supposed to be a.c. shorts for most of the audio range. They are simply d.c. blockers, i.e. possibly the least important of the components in the so-called "audio line". (This excludes capacitors doing duty in filters and cross-overs.)
Recapping xover worth it? - Audioholics Home Theater Forums
2013年1月22日 · There is a lot of uniformed talk on internet audio forums about recapping amps and speakers. Although some aged amps benefit from replacing aged or failed power supply capacitors, I've never encountered an old crossover in a speaker that works like that. Don't confuse these different uses of capacitors.

2017年11月26日 · Capacitors, however, have been the subject of great amounts of chatter among speaker fans – that capacitors made by different makers and different materials generate large differences in sound quality. Most of that info is false. What does matter is that a crossover design keeps the speaker drivers within the audio range where they best perform.
