The dielectric Teflon or otherwise is what really takes the longest to breakin,
This is a falsehood.
If that were true, wouldn’t studios and broadcasting stations burn in their cables for hours? Audiophiles do it, nobody else does.
I agree that standalone audio electronics can take time to reach optimal operating temperature, but this is usually minutes, rather than many hours. Unless you have a big power amplifier in storage and haven’t listened to in a year or more, then yes it makes sense to power cycle it by just powering it on, keeping it on for 30 minutes or so, then powering it off. Helps with preventing internal oxidation and micro-arching overtime. Make sure the relay clicks normally. No weird smells. Although good rule of thumb is to test audio electronics in storage once once every 3 weeks or once a month.
I don’t agree with 20k to 50k or whatever. it’s the INTENTION of the electronics and if their intended PURPOSE aligns with what the customer is willing to pay for.
I don’t find value in CNC milled aluminum chassis that started with 350 kg of material and the thing weighs a ton. I care about the actual INGREDIENTS. It’s like someone serving you fast food in a very costly dinner plate... no thanks.
Else we just get a whole lot of - THIS SOUNDS AMAZING!!! it’s super high end ultra high end or whatever, when in reality it is an interpretation of the original sound that does not closely match what was achieved in the studio. Basically deliberate DSP that is baked in, so you can’t get any more transparency or resolution out of the electronics. You can side-step how it sounds, but can’t chance the inherent character of the sound to sound like the original.
Luxury lifestyle electronics vs Real audio equipment
The real well engineered stuff wins every-time. The calm, controlled marketing language is a winner. The eager and almost unbelievable marketing language is a loser. Doesn’t necessarily need to be costly, just needs to be in line with form follows function.
Difference between audio equipment where engineers had the most freedom, vs where they did not, and marketing departments took over along with management and finance to control cost, but parade around such devices as SOTA when really they are just another kind of sound character that can be easily replicated for less money.
Might I also add, if an audio component is supposedly high end, then ask AI to do a parts check after sending it a photo of the internals for estimated bill of materials (cost). Then you know if it's just fancy casework you're paying for.
