Bloody hell, this is like a Powerline on steroids. Just opened it and hooked up theNova, NAPSC, Oppo and a HICAP for the CD 3.5. Latter two in standby/off.
Playing Ayreon streaming earlier on the Nova sounded so thin and harsh, this has just fleshed out everything so much warmer and deeper - more analogue sounding, less fatiguing. Maybe it’s colouring things, more likely all components are better quality than the cheap 4 way extension lead and it sounds better despite the surge protection circuitry. Or is it the hydra like topology?
It was originally bought for the TV/phone line/computer not audio but seems a real positive addition.
Probably just shows that sometimes while you don’t have a fancy/expensive power block on some components, and are settling for ‘standard/generic’ there may well be a big difference in the construction of a bargain no-name extension lead intended for general use and a standard non-audiophile extension lead made by a more reputable company.
As said above, this looks to do the job of a Hydra. However, it is not the same, despite the earthing. A Hydra has 1 plug feeding captive multiple kettle leads. Using this has another plug and another cable for each box, and I am not sure that adding more junctions is ever ideal.
The other difference is that I have always been told that a Hydra should be used fully - having some cables unused is actively bad for the sound. I don’t remember the explanation. If true, that would be another difference because I can’t see why it would do any harm here.
