Most cap companies make a wide variety of electrolytic caps. It is worth the trouble to find the specifications of a candidate capacitor even if the manufacturer is generally well thought of. As far as specs go, I look for temperature (85C is OK, 105C is better), rated lifetime (multiply by 4 if they are 105C rated), and low ESR at 100kHz.
Modern designs give low ESR at high frequency so they will not blow up in switching power supplies, but that's good for us too. The caps remain capacitive rather than resistive or inductive well past the audio range, unlike older designs where many caps become inductive as low as 10kHz. Incidentally, this is why AFAIK bypassing electrolytic caps first became popular.
Of course, subjective sound seems to involve more than just the specs. The Panasonic TS-xxx series of snap-in electrolytics have had an enviable reputation for a long time, so we have mostly used them in areas where they can affect the sonics. I'm sure there are others that are also good. We may be finding out, given the turmoil and unreliability of suppliers during this recession. :^)
