Be aware if not already that cap life increases massively as the real life temperature goes down. There is a formula for this.
Yep I know, I also know about the "10°C rule" - Capacitor life doubles with every 10°C decrease in temperature. That is why I wanted 105°C rating - to match the original part's spec yes, but also max out on useful life. If those capacitors are rated for 4000hrs at 105°C, running them around say 55°C translates into more than 14 years of continuous use :-)
The amp I'm working on is well built, there are only two caps in each channel signal path and they put polystyrene film there. The 'lytics are for power supply filtering, and support circuitry such as current sources/sink, level shifters etc... Do you think it's worth putting the Elnas you speak about or any other high-grade audio cap in those positions?
I do have a '80s Rotel preamp that I use for its MM/MC phono stage that has 'lytics right in the phono signal path (bypassed by films though), so it could be a good test.
