Best Electrolytics after after Elna Silmic ?

I know this is an old thread, but, i figured it best not to make a new post.

I am in need of a 25uf 25v no-polar type cap for some amps I am working on. I am looking for a good sounding cap to use. most film caps are high voltage and too large to fit so I am looking for alternatives. what sounds good these days?
 
I'm thinking about re-capping an older NAD-C542 cd player, but it may be running a little hot on some of the parts on the PS side. I was told by someone that NAD had used transformers that were a little on the high side of voltage +/- 25V. Suggested I put a DC-DC buck converter running off the transformer. Problem is, not sure which wires I would use? Is there any members here that could give me some pointers? Thanks!
