Quick update.
Mainz D8 with no Ansuz power cables is a decent upgrade. Nothing spectacular. Just a tad more quiet. Then I put in the Ansuz P power between the mains and the wall outlet. That improved things a lot. Much less listening fatigue without any loss of fine detail. Also less background noise, albeit that is rather subjective.
Next the P was replaced by an A power power cable. Again things seem to improve.
Now I connected the P to my phono pre amp. Lets see how that works out. After that the P goes to my integrated amp.
The most remarkable thing about the Ansuz cables is the synergy. I have tried different cable brands in the past, at different positions in my set. Most of them did do something with the sound. When I added more of the same brand I heard more of the "house" sound of that brand.
But with Ansuz it is not just more of the same, not 1+1=2. But 1+1=3. Everything seems to improve. Adding lots of Ansuz cables is well outside of my budget. Especially since my speaker cables are 7 meters long.
I'll do some more testing and post my results.
I suck at writing reviews but I'll try.
BTW all cables were supplied by A10 audio in Amsterdam. I have no financial ties with them or in audio in general. If you ever have the opportunity go visit that store.
