After more listening test I can describe more accurate the sound differences.
All that are my personal impressions with a handfull CD�s.
Most listen to female voices and accoustic instruments and with small and bigger ensemles.
There are three kind of differences,
the bass is just a little bit more precise and accurate and transparent,
the heights a little bit more refined,more delicate more "soften" but without the disadvantages to loose resolution,
but the voices and a little bit the body of the instruments(like a accoustic guitar)
are harder and a little less feeling of the voice/feeling expressions.
That influence is major to the other improvements to my ears.
As I prefer very natural voices -
and if I must decide if I like a little more to hard or to soft sound,i would go to too soft-
I stand with the nonapodsing FW.
But the reason here could be also my personal music preference for musical genre, the remaining equipment and my sound preference,
so maybe other stay with the apodising.
And after more listening, its not a huge step, I could stay with booth variants.
So Mr. Stuart is correct here when he post, that the FW have to be adapted to the specific equipment to get an improved sound in EVERY aspect, not only in certain ranges.
I am more excited und curious now how the M adaption will sound.
I have to say "THANKS MR. STUART" for the explaination which kind of sound could be expected when non specific apodising FW will be used.
My "APOLIGIZE to MR.STUART" for my wrong words for THAT issue.
But all the other items for reliable products and very bad service are still guilty.
This is my experience with M in the LAST years,
not in the first years as I stay with M over 11 years.
The FW upgrade have to be made either as a preset
(as other manufacturer allready do)
to try it out, or REVERSABLE from the CUSTOMER if he dont like the sound.
