this may not really address your specific question but it may help
in your decisions later on...my mod has been burning in continuously
for the past 100+ hrs. and the sound characteristics have been
changing from good to great to "what the..." to good to...etc....
the sound stage is improved but still not ideal...the bass is more
focused but results fluctuate still...having pointed this out, i'll try
to assess what i've noticed in the modded version so far.
i can't be certain of the significance of each upgrade parts and
their respective roles in the findings i'm noticing but, let me generalize
what the single most significant difference is between the stock wa-6
and my mod (described in prior post):
my dad told me something about hifi audio many years ago when i was
just a boy, about the difference between good and great audio gear.
he told me that the biggest difference is in the amount of resolution
you hear at low volume with a superior audio equipment. if i go by what
his definition is, i think i can safely say that the modded wa-6 is a superior
for the first time, i can hear pedal work of a pianist, the breathing of
vocalist, the moistened sound of their lips parting, the spine tightening
rumbling, growling and extended decaying sound of a double bass being
plucked and other sounds one might label as analytical, even at low volume
settings without losing the attractive nuance and velvety smoothness of a
tube sound. it's quite a pleasant thing to hear...it's the first time i can
distinctly notice the subtlety of texture, detail and SEPARATION in a low
volume output. that's not to imply that it is a result of a "loudness" sound
effect...it doesn't sound any "louder" nor seem to be at a higher gain with
a raised floor noise typically associated with higher volume...everything is more
salient, more dynamic but still wonderfully warm and smooth without the
slightest hint of sibilance nor that compressed sound...it's as if
every frequency has been brought up to an audible level without altering
nor shifting upwards the already salient frequencies...
i wish i could convey this in a more clear way but maybe one way to
put it is the analogy of putting a prescription glasses on. you notice
clarity and vibrancy of colors without having to squint your eyes to
focus, making everything a less strain or toll...
