Replacing the stock rectifier valve/tube - is it worth it?

[eliot323]

Hi there
I'm pretty clear about the sort of difference that pre-amp and power amp valves/tubes can make to the sound and feel of an amp, but is it worth changing the stock rectifier valve/tube?

I've done a search but can't really find the answer to this question...

I asked about this on tubeasylum, and the grandees there think it is not worth it unless you change the rectifier type, which you can't do on a LSS. Not sure about the classic though.
