I have never really believed too much into the whole mains power making a difference. But today I stand gobsmacked at how much difference changing a powerstrip to a very good one makes. I have been struggling of late with my system especially since changing my speakers. Something was off and I was beginning to think the speakers where the issue as everything was too bright and harsh in the top end and I could hear some slight distortion.
So after exhausting most options I kept reading about how poor mains kit could cause excessive brightness. So after a bit more research I decided to change the filtering powerstrip I was using, it was not an expensive one but had helped when I had to use powerline adaptors for networking. So I ordered in a Russ Andrews powerstrip and their basic mains lead, along with an audiophile one from MCRU to compare.
The Russ Andrews arrived today and straight away it started to sound more cohesive. Tighter cleaner bass, less harsh treble I was very impressed but I could still detect a little distortion. So I decided to move the the Roon core and switch to the same strip and it all fell into place. I can’t believe the difference its made. It’s brought back the enjoyment of my system and now the new speakers sing. I think I might get another one for my phono side of things as they are powered from a different strip as they are not with the other kit.
