Heh, heh!  Ear training? Flat frequency response with mid-fi or
lo-fi results?  What has happened here?

Let me try the question again with clarification .  What is
meant by tigntening bass and taking edges off of piano as it relates
to things that happen to the specifications of audio equipment?
Since something must happen (changes can be heard by the "finest
and most sensitive instruments -- OUR EARS") then this obviously
MUST be measurable by any reasonable test equipment (which clearly is
less subjective and EVEN MORE SENSITIVE then our ears.  

Is there another domain of sound reproduction that has escaped 
detection by electronic instruments but is be obvious to the ear?  
Don't give me this "you can hear it but I don't know why" stuff.
I hear that from stereo store sales people and its garbage.
Everything happens for a reason and anything that can be heard
can be measured.

I'm all for using ears to judge quality.  That's not the issue here.
If someone does know what is happening with the CD 1040 mods
and can offer a rational explanation of why, fine.  I want to
learn.  Maybe we can all learn.    Maybe even some of us can develop
less costly and equally useful methods for accomplishing the same 
results.

We owe it to thousands of CD 1040 owners who might well be sending
their machines to fix it places and spending lots of money on things
that can be had in other ways.  I challenge someone with a modified
machine to characterize their machine and compare
it with measured specs
before modification.  If changes occur to externally modifiable
performance (freq response for example) I would argue that an
equalizer can produce reasonable results.  If S/N ratio or phase
tracking or some other "only internally correctable" characteristic
is affected we've got something going.
