Recently got myself RCA 6AS7G power tubes and Sylvania 7308 JAN NOS drivers to replace WA2 stock tubes.
Wider & deeper soundstage, blacker background, smoother sound all around.
And yes, the bass coming from Mega City One (Dredd Soundtrack) used to be very good now it is awesome.
Mass string section of classical tracks can breathe easier.
Very nice upgrade but not cheap. The RCAs used to be
much cheaper, I heard
