Is there any sonic advantage of keeping your amp on all the time? I think i noticed a bit more smoothness in the sound when left on for over 24 hours.
Also is there any harm in keeping amp on all the time? ie parts wear out sooner.

Paullieb213Capacitors do wear out. The harder they work the faster the wear. So idling might not put much strain on them.
Most other parts I know of only go bad if you use them beyond their specs (like having a 1/4 watt resistor using up 1/2 watt).
I have my doubts you actually hear differences though. You could be cutting the life expectancy of your amp in half.

reiszrie Tell that to Paul McGowan. Who has had his amp on for 5 years with no sign of degradation.
Im also sure that the sound is smoother with amp left on.

Paullieb213Well, no offense here and not trying to be disrespectful but taking a singular anecdotal evidence as truth or fact isn't helpful in truly furthering one's own material knowledge.
While such events as described might have been true a long time ago, it has long since been debunked as a myth, reason being that modern circuitry almost always includes an ICL which prevents the very issue described
https://en.wikipedia.org/wiki/Inrush_current_limiter
https://www.ametherm.com/inrush-current/ptc-thermistors-for-inrush-current-limiting What this means is that since turning a piece of equipment on and off no longer exposes it to inrush current, whats left in keeping an electronic equipment on 24/7 is simply the degradation of circuitry and capacitors, since all electronics with current flowing through them is bound to suffer degradation. Audio equipment is engineering at its core, its not some mystical arts hence to suggest that keeping an equipment on 24/7 results in "smoother sound" is equivalent to saying that a computer runs faster and "smoother" if kept on 24/7 and to achieve best performance, users gotta let their computer's circuitry "burn-in" first. There are plenty of pseudo-science crap going around in audio communities and it is important to not take everything as gospel.

reiszrieThis guy is a legend in the industry. This video was from 2 yrs ago. I would appreciate your comments. I also sent him an email with your response. Lets see if he answers.

Paullieb213I hope you find the answer you're looking for but if you're already so invested in pseudo-science, there really wasn't any need to ask this question here to begin with. Objective and scientific answers aren't what you're seeking, reaffirmation of your pseudo-science beliefs is what you seek.

Paullieb213don't resort to fallacy, specifically an appeal to authority fallacy.
If you can't take sound reasoning, then thats fine, you do you, you live your life the way you choose to, and you can believe in any pseudo-science you prefer as well, just like how some people join cults.

Paullieb213Oh, did you also hear that leaving your car running makes it run smoother and faster too.

Paullieb213You continue to see yourself as the sole authority on this subject. I will ask you again. What are YOUR credentials?

Paullieb213I'm just someone with common sense and sound reasoning, it also helps plenty that I'm not subscribed to a cult where I salivate over some audio guy from PS Audio, kiss his feet and the ground he treads upon.
Again, you can keep your amp on 24/7 for all I care lol

Paullieb213One last comment. I do it because the amp sounds better. Smoother more detailed with tighter bass. If that was not the case i would definitely turn it off after listening to it.

Paullieb213If leaving the amp on for a long duration improved things, it'd be a common metric mentioned before taking measurements. Perhaps it's prevalent for pseudo science companies but I haven't really seen it mentioned. I've heard of burn-in for like audio-gd amps but they measure like shit anyway - or in other words - pseudo science company. You can say audio-gd sounds great but what you're calling great would be considered defective compared to 789's specs.
Paul from PS Audio is a chill dude but he believes the quality of your usb cable makes without question or doubt an improvement to the sound quality. He believes in many such things. I suspect he does it to make sales to people looking for conformation bias. I used to watch some of his vids in the past to try and understand what goes on in an extreme audiophile's brain. I will say he at least often has reasonable thought process to why he thinks what he thinks. I just don't think the difference are within what can be possibly heard.
When people say they hear improvements after doing xyz, I really question their methodology of how they came to that conclusion. ABX testing is kind of the only way and is often difficult to conduct and/or expensive (needing to buy 2 of the same amp for example).

Michael-QI dont know maybe its me but i can hear differences in 2 wires that are from the same company and same model number. For example I have 2 evergreen audioquest cables that were bought about 1 year apart and sounded different. The second cable sounded more detailed with more clarity than the first.
I have had two monoprice thx 887 amps and they did not sound exactly the same. I have had 2 denon power amps that did not sound exactly the same.
Some people can hear these small differences and others cannot. But there are in my opinion differences.

Paullieb213Yeah, what you say is quite hard to believe. Even if you said you used abx testing methodology I wouldn't believe most of what you just said.
To be clear, I don't doubt that you think you hear a difference. It's more of an issue if there really is a difference that's audible. Audio is weird in that when you think you should hear differences you do hear differences. More power to you though if you believe it and it brings you some sort of satisfaction/happiness.

Paullieb213hahaha! I have a set of magnum opus cable to sell you 😹 yeah, all ya pseudo-science snake-oil believers will always claim to have platinum ears with god-realm hearing ability.
but hey thats why cults exists.
