Coupling & Bypass Capacitors
https://sound-au.com/articles/coupling-caps.htm
3.3 Power Amp Bypass Caps. Power amplifiers are generally comparatively low speed, but bypassing is almost always needed unless the amp is only millimetres from the power supply. It is fairly common for power amps to use bypass caps ranging from perhaps 10µF up to 220µF or more, and these are often in parallel with smaller caps.
Audio Research Reference 3 Bypass Caps Question
https://forum.audiogon.com/discussions/audio-research-reference-3-bypass-caps-question
Different caps have different extended series resistance, they have different dielectric constants (even if made from the same material) and as a result the signal gets smeared if the bypass is present. Part of this is that the coupling cap at the output is directly involved with the output impedance of the preamp (being a series impedance with ...
Decoupling Capacitors and Bypass Capacitors – Working ...
https://components101.com/articles/decoupling-capacitor-vs-bypass-capacitors-working-and-applications
The bypass capacitors are almost used in all the analog and digital circuits for removing unwanted signal from the supply voltage, some of the notable applications where they are used. They are used between amplifier and loudspeaker for a clear audio. Used in DC/DC converter. Used in signal coupling and Decoupling.

But wait, there’s more: There’s one other critical place for this bypass treatment that is almost always overlooked – the output stage cathode bypass capacitors. Electrolytics used for cathode bypass must be replaced or bypassed with good quality polyethylene types for the best sound—even though they can be rather expensive. Very few amp restorations, or even …
Bypass electrolytic caps in audio chain? | diyAudio
https://www.diyaudio.com/community/threads/bypass-electrolytic-caps-in-audio-chain.276484/
While replacing the electrolytic caps (10/43uF and 25V) in my in/out audio signal path of my audio interface, is it worthwhile to also bypass with ceramics? Like a 0.1uF 50V X7R? on each? Or is this primarily used for PSU caps?
Bypass cap? - Techtalk Speaker Building, Audio, Video ...
https://techtalk.parts-express.com/forum/tech-talk-forum/13496-bypass-cap
A bypass capacitor only 1/1000 the main capacitors size that is not in it's inductive range will have the same impedance at 120khz that the main capacitor has at 120hz and will thus be able to extend the range of the main filter capacitor. That is why bypassing is a legitimate practice in some situations but not for speaker crossovers.
Bypass Caps: Decouple Your Way to Cleaner Power
https://macrofab.com/blog/bypass-caps-decouple-your-way-to-cleaner-power/
Bypass capacitors are an absolute must to avoid issues with noise on power supply traces and cross talk between devices on a PCB. Every IC in your designs should have bypass caps placed close to their power pins to provide low impedance paths for reducing the impact of current transients. Whenever available, it is best to use the manufacturer’s …

The Obbligatos are audio coupling capacitors, but not DC supply bypass capacitors. So the Silver-Z caps would also be audio coupling capacitors (in parallel). Their major affect would be to drain your wallet.
"Bypass" Capacitors in Crossovers - The Klipsch Audio ...

People copying things they don't understand make mistakes. Drew Daniels and I were looking over the network drawings for the 4430 studio monitor when he remarked on the 0.01µF bypass caps on the film caps in the woofer section, muttering to himself that "use a bypass on all the caps didn't mean the ones in the woofer section".
