The Caddock TF020R are easily the best resistors I have tried in critical places.

Theres a few places like the nulling circuit on a dacs output where BG N types could not be bettered IMO, they always seemed to have the least sonic signature but just throwing these caps all over the place does screw up the sonics.

Rubycon ZA's can work well too

I don't like Oscons, SEP series can work well in clock circuits
