Just because your Panny works fine (so does my XR25 and XR45's) doesn't mean you should be sure the components aren't packed into a sub'optimal' package.
And I'm not trying to say 'it's less than perfection'. I'm saying it's really just a little too corner-cutting.
Your XR55 doesn't have a fan like the XR25 and 45's. There was a reason they had a fan. It was the reason I stated.
That reason is still in your XR55 but they added a small amount of venting and slightly taller box to get a bit more air flow. You might not know how hot it actually is inside and I assume you don't check how hot it gets often so it just visually looks fine and audibly plays fine -till something overheats and dies.
It's 'ok' but not good enough for all.
Part of how and when your Panny would heat up is based on how you use it and factors like where you put it in relation to other gear and how cool your room is in.
You probably have these factors covered.
For my Pannys I unscrew the unvented lids and tilt open the back. It actually locks in place like this on the case and vents the whole back with about a 1" slot above the back panel.
The fan is designed to kick on with high current which means louder sounds so the fan sound is 99% of the time covered up. But the PS heats up the most when the unit is playing low levels where the fan never kicks on.
Again... not the same design as your XR55 but it's very similar and it can get very hot in there.
The JVC recs are even more known for this too.

I got my XR45 modded and price to perfomance ratio it was a rip-off, but understandable 'cuz it was hand-done work.
There was an improvement though and you'd have to pay quite a bit more to buy something else to get similar I believe so in that it wasn't a rip-off.
I wrote back when I did the mod that I really wish Panny would do some of these things on a mass production basis so like you said, it wouldn't cost more than a few hundred more to get a really tricked out design.
The newer Pannys like yours got rid of a retarded 2 cent 'snap clip' speaker outputs but the connectors are still dirt cheap.
They got rid of the fan needed to cool a 'too small' box, but like I said... it was still a dirt cheap fix and not a good enough one.
From all I've read from people cracking open the latest Pannys they still have a tiny power supply too. The XR45 still seems to have had the beefiest design.
BTW- switching from a Pio DVD player as my CD transport to my modded XR45 to sending it ripped CD from my PC's hard drive for all my music seems like about as big an improvement as the 45's mod.
