Vovk Z, in recent thread argued about interest of keeping some caps on drawer.
I agreed with him as local resseller disapear and online orders require a minimum amount.
which aluminium caps will you recommend or kit (if exist) for inputs of audio circuits ?

The value of capacitor depends entirely on the circuit chosen, impedances and frequency etc.
A capacitor is a capacitor.

Agree with Jon. Caps cover a WIDE range of circuits and values. Are you working on old tube amps? New tube amps? Old solid state amps? Now solid state amps? Low voltage circuits? MAins powered circuits? RF?
Working on Fender amps for example, I might find 22uf/500v and 25uf/25v very common. And I'd have little use for those working on powered subwoofers.

I generally keep 50 v versions of these values around, in the grades 5000 hours service life or longer. I don't want these expiring on the shelf as red gum rubber (500 hour life) sealed caps will. Nichicon, rubicon, panasonic from the big 3 distributors here, newark(farnell) digikey, mouser. You have other reputable vendors in UK or Germany however. As my stock caps go beyond "shelf life", I charge them up with the ohms scale of the DVM before use to reform them if necessary. Within shelf life means they can be hammered with 100% voltage first thing after installation.
4.7 & 10, I keep around film caps for if I can fit them in. These tiny ones are particularly prone to dry out.
Watch 20% grades, modern caps tend to be all 19% small instead of being random value like caps were in the seventies.

Farnell & digikey will let you see the hours service life spec in the selector table. Mouser makes you download the datasheet. Different values of cap have different service lives even in the same product line.
RS, reichelt, you're on your own. I don't order parts through customs, they get lost sometimes, even from the UK farnell warehouse to the US-NC one.
I've used several of those series, don't find any **** caps in the 5000 up hours grade. Only for switcher power supplies will I order low ESR caps or anything otherwise special. "Audio" grades, hoomph. Waste of money. The industrial grades sound fine in equipment listed in post 5.

I use mainly Farnell (overnight delivery) and mouser (3 days from US).
Among criteria, I choose 5000 hours or above.

I think Mouser and Digikey are probably the most expensive way to buy electrolytic caps in low quantities. But it is convenient, you have many choices and they are authorized distributors for most of the top brands.
If you want low quantities of different values, my suggestion would be to buy Rubycon capacitors from LCSC. For example:
35V 100uF 7000h@105°C
35V 47uF 5000h

Seriously? , venture to guess how many ecaps a typical music source goes through before you get to hear it?
