The R5/R6000 does not need a "better quality matching network."
If you want to replace the capacitors with something a bit beefier
that's fine.  Otherwise, an external common mode choke might offer
marginally better feedline decoupling than the common mode choke
already included in the R5/6000/7/8 matching network but there is
absolutely nothing "wrong" with the stock matching network as long
as the user does not force power into it on a band that is is not
designed to cover (e.g. 80 meters - or 40/30 on the R5/R6000).
