Ive used several and have settled with Pure Power APS 2000. This is a conditioner and re-generator like the PS PPP. The 2000 also has a battery back up included in its one box design. Extra stand alone battery units or available. The battery showed its use last night as we had a short loss of power. I did not miss a note of Led Zeppllins The Song Remains the Same on Lp. I also have noted increased air definition and a super quite back ground with micro details abundant as never before. I have not noted any negative effects using the PP2000. I started with just my Nuforce amps and added one component at a time and have the same positive effect. Highly recommended.
Power conditioning
I'm looking for a power conditioner for my McCormack DNA125; I'd also use it for my McCormack pre and my NAD CD player. There seems to be a lot of choices out there; my local dealer sells the Panamax, but so far I'm leaning towards the Hydra or Quintet. And advice would be welcome particularily from Steve. Thanks.
