The PS Audio Power Plant is amazing particularly if you have crummy and noisy AC like I do. I was highly skeptical and ended up buying 2. TAS review is accurate in my opinion. You will need a good shielded cord from the Power Plant to your equipment.
NBS vs PS Audio: Advice needed.
I am considering betweeh the NBS BlackBox+SignatureII and the PS Audio Power Plant (P300). There is a mint Black Box with NBS Signature II power cord set going for about $1000+ in the web. While the PA Audio P300 is about $995 +. While the price is one issue to be considered, I am more concern about the sonic benefits of the two - one is basically an very good A/C extension; the other is a raved PLC. Any suggestions?
