Upgraded power cord for those that care.

So you are going to make me ask? What problems?

Squeezebox Classic burned thru 4 of stock & higher ampacities before I replaced with a Chinese linear off eBay (ZeroZone). No issues since, plus it sounded a bit cleaner...more natural.
Topping D30 started reflecting high frequency noise into my phono stage. Tracked it down to the wall wart. Replaced with a "better" one.

Plus in 25 years in equipment calibration & support at my current employer I've replaced at least a dozen various wall warts. They never seem to overheat...they just die a silent death. Newer equipment has shockingly short lifespans (and shockingly short mfr support) and it's typically the PS that dies.
Meanwhile all the older gear with linear supplies just keep *working*.

(and in the case of switching power supply...outsourcing...for repairability etc.)
 
So, even anecdotal evidence seems to support that wall warts die early, not built-in power supplies. ;)

It is possible that wall warts use cheaper components and get hotter due to lack of space and lack of ventilation if in a poor position. Having said that I wouldn't care if a wall wart failed if replacements were easily available. I would be annoyed if a built in power supply failed.

unfortunately it is the same in very high consumption devices, ""planned obsolescence""" .... I do not judge the results, but the linear ones are much less delicate and easily enduring....
without thinking about upgrading tweak mods etc.. outsourcing, when it is easily possible, can have some good...
 
Most my vintage equipment has internal power supplies that have lasted 40 or 50 years, I'd say internal supplies are better.

I’m not debating that, I’m debating that switch mode outboard supplies can sound just as good as linear done right. And be more efficient

Take for example, my project DAC pre-box S2. Why would they want the power supply to die. I’ve had it for 5-6 years now never a problem dead quiet. A new power supply for the project is probably 15 bucks 20 bucks and if I replaced it, and won’t be a project power supply. It’ll be an aftermarket. They don’t make any money out of that. So why would they design it to fail? Not making me a believer in this thread

I thought the point was that if the power supply is internal it is a lot harder to repair or replace than an external power supply. If an internal power supply fails you could be forced to replace the device. If that happened to me I wouldn't be rushing to buy another from the same manufacturer so they still wouldn't make any more money out of me.
We bought a Philips Sonicare toothbrush which failed within the warranty period and was replaced. The replacement also failed within 18 months but was no longer covered by the warranty. Our replacement did not come from Philips.
 
I have only ever the internal power supply fail one device that can recall . A PC. That said I’ve only had a couple of external ones that you Yanks call wall warts fail.

TVs have had SMPS for decades and I've never had one fail. I did have one fail in a video recorder.
