For a long time I have been using various parallel power filters and power distributors, devices from Isotek, MIT, Audio Magic and PS Audio.
But I was surprised to find the Nordost QB8 v2 beat them all and was the best in my system. I initially dismissed it as an empty box. It just has a simple looking PCB inside that apparently does some kind of star ground lift and nothing else. No filters of any kind.
I am using Nordost Heimdall 2 power cables, so perhaps there is a synergy with those cables, and it's possible with another brand of cables the gains using the QB8 would not be so apparent. So I can't say if the QB8 will work so well for everyone - but I am sold on it.
And it has a ground post to continue the Nordost upgrade path to add their new QKore grounding boxes (or something like the Enreq).
