I used to power everything off tacima blocks And thought they were very good. After having issues with one and my power amp i realised they do exactly as some people say restrict the sound.
..and you wonder why currently employed engineers don't post on this forum.
Given the stance of certain brand of amps, Ellis's findings are not unreasonable:
Plinius - "Most mains conditioners or filters act in series with the mains and will starve the amplifier and negatively affect the sound. Look for a brand that works in parallel. If you need this treatment to your mains supply, this is a better option for you."
Gryphon - "In our experience, most external powerline conditioners do more harm than good. The sound may be very different, but not necessarily an improvement. Listen very critically and for an extended period of time, before making a final decision about purchasing a conditioner. Gryphon products incorporate heavily regulated multi-stage power supplies which act as effective mains conditioning filters and will in most cases not be improved by the insertion of an outboard powerline conditioner in the signal path."
Sugden - “We don’t use mains conditioners but if somebody wants to, they need to make sure it has the correct power rating. Line level equipment such as CD players and pre-amps have very low power consumption but Integrated amps and power amps require a mains conditioner of much higher rating. Using a mains conditioner assumes the equipment needs it. We spend a lot of time designing our power supplies and carefully choosing the rectifiers, transformers and smoothing capacitors. From my experience, most conditioners used on power amplifiers reduce the dynamic range. The best power supply for a system is a separate spur from your fuse box, this might even be less money. I am of the opinion you need to be as direct to the mains as possible with our class A amplifiers. Experimenting with an isolation transformer is interesting and quite a big one isn’t too expensive to run amplifiers from.....as our mains conditioning experiences have been quite negative we have left it alone.”
