I too have been using what I call SSBB SubSonicBassBoost for several years now and it along with a few other tweaks can go along way in delivering kick ass bass on 800's.Then you will not hear THAT bass. Try eq-ing the bass up. It is fantastic. It is one of the best bass Ive personally have ever heard.
Which tube amp are u using? In general, try to avoid OTL. It fixes the tonality, but I feel soundstage and detail takes a hit. But of coz depends on the amp as well.
My bottom end EQ is simple.
I go into the parametric EQ inside MediaCenter and use these 'starter' settings.
Q= .52 Freq = 14hz gain is +15dB
and
-9dB left and right, so the bass boost isn't clipping nor 'mis-behaving'.
This curve fairly closely matches the natural fall off, of the 800's.
And I would suggest playing with those 'starter' set of ParaEQ settings, to suit you and your system
And Sonar works using the unlimited EQ set of 800 curves works rather well as well.
And I agree that tubes can do a marvelous job with the bass on 800's.
And a trick I just figured out that may be old news to some but bears repeating, just because.
If you are running high Ω cans on speaker taps from a tube power amp try this trick.
Add 15Ω resistors of say 5-10watts (or less depending…) across the 16Ω taps, for Senns and anything over ≈ 100Ω.
This should help run the tube closer to its 'sweet(r) spot'.
It sure did for my BIG 45 amp.
