ARC Ref 6 tube replacement

Looking to replace stock tubes in my Ref 6. Anyone replaced their stock tubes? I also heard that that the NOS Tung Sol 6550 is an excellent tube for the power supply. Anyone have knowledge of this?

My tube replacement for the REF 3 by the blackplate tungsol gave me the following impression : bass tighter , more refined and more resolution .

I also thought about trying the SED 6550 black sable. Was also wondering about the NOS Tung Sol compared to the new remake Tung Sol 6550.
