Is there any advantage of XLPE insulation over bog standard PVC ?
What a rip-off. You really can't pay those budget prices when there is....
SWA mains cable has XLPE insulation, can be installed at temperatures down to zero C and even has shielding. It would make a perfect replacement for the signaturex cable at a slightly lower price.

They will sell you a replacement fuse for it as well - a snip at £65!
You get what you pay for. The Russ Andrews cable at £2100 is twice as good! And, don't forget the spare 13A main plug fuse at £25 each.
Tensile strength is the only one I can think of, hence the widespread use of XLPE in distribution power cables.
The main attraction is it is not as thermoplastic as PVC, so you can run a max core temperature of 90 deg C rather than 70. So you get a higher current carrying capacity (at the expense of higher losses).
Of course, it's worth every penny for that last 1m to the amp.
The problem is paying the whole street to be rewired, right back to the substation.
So now I only play vinyl during daytime, when I can run this on Pure Sun Energy from up on the roof.
Ah, but how smooth is the sine-wave from your inverter? I'm sure someone will sell something to smooth it out ... for the price of a new car! ;)
No, it would be much better to use the dc directly. Maybe 600V from a string of panels would nicely match a beefy valve amplifier. No need for switching converters or big power supply transformers. Maybe use a separate panel for the cathode heater supply - with linear regulation of course.

I think that about 480V is enough for my amp, but 600V and some regulation would maybe cater for passing clouds.
Of course. But I reverse the polarity between tracks, to avoid all the electrons ending up pushed to one side.
