I've tried LOTS of them, and although they changed the sound, none of them changed it for the better on my system. Audition them in YOUR system for a few days, remove it and listen again without it and then determine its worth.
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.
