One of the things that solicited me to try the APS unit was the assurance of the APS guy (Richard) that what I run ASP unit from internal battery + regeneration vs. the plugged in wall + regeneration ….I should hear no difference in Sound. From what he said I can make ONE of the following concussions:

1)The APS unit is the real God-send thing the does properly decouples the load from the mains.
2)The APS unit produces so much crapy noise in the regeneration mode that it overrides the nose of the bad mains
3)The APS guys who tried if are deaf or are clueless what to listen while they are listening
4)The APS guy juts lie.

Well, will see what happens….
People who know me know that each year, staring from May, I take the subject of bad sounding electricity personally. So, each year in beginning of the summer I commit myself into a new round of celebration of my stupid optimism over Reality and drug home a new power line gismo. The gismos usually loosing the battle with sound and I, keeping bitching to the end of November when the electricity regularly become better, continue to live in the audio-electrical misery. It is me. I am accustomed to myself…

This year my May’s ceremony included the APS PurePower 1050 regenerator.

Look at the last pager of this thread: http://www.GoodSoundClub.com/TreeItem.aspx?PostID=4480

I got it today; I put it into the playback and here is the very short register about my initial experiences. I write it up not only for you guys but also for myself: to organize and to log my thoughts. I am not making any conclusion but juts the pass the testimony of the observations.

The electricity today is, thanks God, horrible so the PurePower will have the things to do. I played only digital (what else is necessary) and the only one recording: the last movement of Pathétique by NPoR. If the “Adagio Lamentoso” was OK then the Third movement. Uselessly it never reach the needs to play the Third movement as the crappy electricity in the “Adagio Lamentoso” converts the sound of the second violin section into the buzz of zillion mosquitoes and the cello section into the fart of submerged turtle …. the  game typically over as is…

My CD playback in my elecro-summer configuration: TL0 and Bidat run from P300 (with removed common mode filter), the super Melquiades run from own dedicated lines, untreated; and the Preamp run form own untreated dedicated line – unfortunately it is imposable to use P300 on analog gear as it fucks up sound more then bad electricity (making bass rubber-like, thining upper MF, screw up harmonics and many other negative things).

So, the first thins I did to plug the PurePower to dedicated line and run preamp from it. It was very nice. The sound was not ruined as it would be as I run the Preamp from the P300. In fact it was very pleasant and very delicate. Then I switched the DAC and CD transport to PurePower. Absolutely wonderful result! The dynamic not even compare to P300 with phenomenal articulation and with no detectable impact in tone anywhere across the entire range, the bass is as it should be and not “intensification” of sound anywhere. The stings are very clean, very vivid and…. Did I mention the dynamics?! It is kind of very dynamic and bold but very elegant and very smooth and with not lost sounds popping up here and there – very-very pleasant. I added 6dB on the Water Drop tweeter – not problems – not negative impact. The P300 sounds in this context very pale. Still, subjectively with all colorations that P300 has it has more noise rejection then PurePower as among the stunning dynamic and verbalization elegance I still can here some very minor artifacts of the bad electricity – however those artifacts looks like do not impact sound in negative way.

 The PurePower show up the 2% or full load and I decided to pull up the power cord from the PurePower. The use is switched to the butteries on fly and… the sound practically did not change… extremely cool. I do feel that from the butteries it was a bit softer but at near negligible amplitude.  Frankly speaking I did not expect it – very positive and very promising effect.

Being pleased and enthusiastic I plagued the super Melquiades to the PurePower. The amps went off on, the PurePower handled it well. The both Super Milqs (juts 3 channels for now not 6) at this cruse plate current pushed the PurePower to 70% of load. The sound went completely to toilet. It is absolutely grey, severally compressed, with absolutely no dimensions - flat like the Berlin Wall from the East side during the 70s – juts horrible… I plugged it back to the deded wall a few times – the effect the same – with my power amps this thing is unusable.  Switching back to PurePower the front-end  - very-very nice!

Hm, I do not know what to say… I will try to masseur the PurePower later on and what is going on…

Posted as is…Reading at you own risk…
