Ah yes - foo stuff.
Had the original audioworks recoil + mains block powering my stuff but upgraded about 3 weeks back after a decent home trial.
Now have a 3m cable to the new block which has an iec socket rather than a captive lead. From this are 3 other revive leads to the hardware. These new cables have a mesh shroud over a double run of the original cable plus a few other changes I'm told. The terminations are Furutech rhodium plated 3 pin and very fancy iec at the hardware end.
The bottom line is a substantial increase in image depth, ambience and drive into the system. It sounded good before but it seems like it's been turbocharged. .
One thing surprised me - I use a Vertex Jaya which was plugged ito the adjacent wall socket after experimentation with the old power cables. With the new cables everything sounded a bit plummy with a narrowing of the soundstage and a lack of air around brushed cymbals and the like. I thought at first it was the new cables and was going to have second thoughts. Then I moved the filter to the block instead and - hey - everything opened up again with the advantages that the new cables bring well in evidence.
Why I know not but that's how it is. Foo sceptics need not comment.
