Achieved improvement in sound

As part of the new purchase of high-quality boxes (Vroemen La Nobila Ceramica) with cabling to SANSUI amplifier (AU-X 901) I was advised to check at least whether the 08/15 cable from the Marantz CD player 67SE should be renewed.

So I ordered the Oehlbach BEAT!
Here could be seen at once that the sound was thin and the balance is lost.
So .. old 08/15 cable reconnected.

Then a last attempt: Oehlbach NF 1 Master NF Audio pin cable ordered.
Direct comparisons showed that this cable slightly improved the sound:
- Nuances improved transparency of the sound
- Volumigerer sound without "reinforce" the bass
- Smooth playback of individual instruments with better positioning in both speakers.

I know it's hard to describe these "little things" - but as a conclusion it can be said:
the sound has been improved with me to nuances, ie clean.
However, the question whether a sonic improvement is also achieved if the components are not so high remains ...
