Post Subject: Which Parts are the Good Parts?Posted by Paul S on: 12/3/2011

Decoud, this is a delayed response to your most recent post in this thread (posted 11-14-11): Indeed, why is it "beneficial" to add DC/AC to a battery only to rectify it again? This has never made sense to me, except with my fuzzy "theory" that the PP DC/AC conversion process somehow produces a "useful dithering effect", or something like this.

Along with 'scope traces shared in this thread, we are told that "acceptable" sound yet comes from "less than perfect" AC sine waves via the big PP outputs. And in my world, if the electricity contributes to better sound, then the electricity is acceptable, whether I "understand" it or not. Also, remember, the majority of PP users in this thread have said they prefer the sound derived from un-plugged unit. Hmmm... The un-plugged unit not only avoids/bypasses both the wall power and the AC/DC conversion process, but it still uses a battery AND a DC/AC converter. However, I think it would be quite difficult to reasonbly "compare" the unplugged PP to straight (DC) battery power, if only because of the differing power (supply) designs for the "test gear".

Still, a good question, and an important one, IMO.

Best regards,
Paul S
