replacing Audio Research power chords

I have an Ark Ls 2 MKII preamp and D-200 solid state amp

Both of these are factory wired and not removable chords. Does AR or anyone else do mods on the AR for removeable power chords.

The AR factory chord is probably much better than most standard chords but I'd think it could be improved on

AR's later models do have have removable chords

ANyone had any experience or input on this end

thanks
