It could be that any form of digital reproduction is inherently more influenced by the vagaries of AC power than analog playback. Only when you can supply the digital device with very clean power will it play to maximum potential and all traces of digititus will disappear. Some cases in point would be Red Wine Audio's battery powered amps and the Dodd battery preamp.

It seems to be exactly that.....CD/Redbook (possibly any digital) improves to a greater extent with power conditioning that turntables seem to
In my case....my CDP is fed 12volt regulated DC (from an outboard Radio Shack power supply). The two turntables used
both have DC motors. Yet, it's clear, CD playback benefited more so than
analog player.
So, it's not a case of comparing AC versus DC motors with different front end formats...
they are all DC...yet the CDP
clearly benefited to a greater extent.
I don't consider the change with the Audience to be a component level upgrade....but it is a step in the right direction, nonetheless.
Consider my system possibly unique in that I use tube monblocks...that were original PA amps...so they have no filtration. A 30 year old preamp (that sound great), that I believe has no internal conditioning and not much capacitance and a very cheap (but very decent sounding CDP) that was built for a low price point....and had it's switching power supply replaced by a Radio Shack regulated linear one (with much improvement).
Those of you that have higher level components, with designer attempts at stiff power supplies and or choke regulated or actively filtered...may find the additional of the Audience to offer no improvement. But, for me, it is clearly a nice change of sound for the better.
There - just wanted to state that in case someone found no benefit from it and bought it based on my rave here
