Regarding the tape mod,
I have experimented with bass knob
set at min and max respectively.
I am sure many people did it with min bass
so I leave out this part.
With max bass and tape on,
I found myself immediately in love
with how the sound was delivered.
I can't get enough of it right now.
The power of bass remains the same
but becomes much more focused
and thus dives deeper.
Benefiting from the tape mod,
the mid bass is also well controlled.
Bleeding problem solved.
And of course more details and clarity
can be heard with vocal pushed a bit upfront.
The disadvantage,
to some who tried the mod and then gave up,
is the shrinking of soundstage.
Indeed, with max bass and tape,
the sound ends in enclosure, not expansion.
Especially the vocal ending direction is inward.
Personally, however,
I like that strange intimate feel,
giving me more creeps, in a good way.
