If only to show that not all sound improvements need to cost silly money, I thought I'd write up a recent discovery which, while more of an emergency measure, demonstrated how even low-cost power conditioning might improve the SQ of our Meridian systems.

By way of some background, it seems in December one of our neighbours put in PowerLine adaptors to get around the networking issues inherent in new-build properties; the signal from which not even the Shunyata kit could eliminate and the sound stage completely collapsed.

After some reading up on the topic, the quickest fix turned out to repurpose a Tacima mains conditioner sitting in my study (costing all of £35 from Amazon) to feed the processor as a stop-gap measure. The sound stage not only went back to how it was, but I think actually may have improved the focus (although, perhaps not all areas of the performance).

I'd recommend against using this solution for DSP speakers, though. I experimented with this and the sound ended up feeling really clinical, losing any sense of realism.

Definitely worth considering for a processor. For the price, I'm not sure it can be beaten.
