hello all,

After some talks with a friend of mine I exchanged the op-amps in my
two a-119s.
The a-119 uses a TL064 IC as a standard. You can just exchange this
for a TL074 which sounds a bit better... The CV tracking does not
seem to be affected.

The overall result is a better bass response and a (to my ears)
creamier and directer sound.
Of course this is all very subjective but for the 95 eurocents per IC
I was willing to try..
And because the IC are not soldered on the board you can easily do
this mod yourself..

While I was testing the new op-amps in my a-119's, I stumbled over
something less cool.
It seems that my two a-131's are differently calibrated in their
response to CV. Does
anyone else here have this problem too

Greetings,

Ernst
