Great to hear N80. An old trick to get rid of or at least dampen some resonant bass from big speakers. Socks do fine as long as you don't see them. Maybe different socks have different effect on the sound, I don't know :-).
Like to say that I (again through Tidal) discovered a fine band The Guess Who. Lots of great music, both sweat and hard, good solos, good singing with harmonies and some really beutiful airy recordings in the "old" way. Dynamic "real" drums.
