At this point I am absolutely confident the there is difference in Sound between the properly sounding PP2000 that I had before and the “new” version of PP2000. Let juts for sake of illustration I will call it PP2011. The PP2011 is better sounding unit – I will explain how, why and provide further elaboration on the subject.

 As I understand Pure Power sometimes in 2010 made a new version of their PP2000 model. I have no knowledge what they changed but it was a new version of motherboard where they addressed whatever the intended to address.   As I understand that had a bug in new version or a bug in a specific production run, they reportedly fixed it. It looks like I have a taste how the new PP2000 (or PP2011) sounds and I am telling you it is very impressive. It is so impressive that I think Pure Power were foolish that they did not introduce the new revision as a separate mode. In audio we are very much accustom that a new model is introduced when a company change a location of a fuse box or change the straight head screws to Philips heard. In case of the PP2011 it is ridicules in opposite direction – the new unit sound significantly better but no one notified, the fucking revolution was not announced!

Ok, the “significantly better sounding” and “revolution”, did I really mean it? No, I did not. There is no revolutionary change in the PP2011 performance but there are some notable differences. I will describe those differences. Mind you that I have no old version of PP2000 and my observations are purely subjective and based upon the constitution that Pure Power regenerator inflict to the sound of my playback. Read my 2-3 posts above to get the context of my observations.

So, here is what I discover different in the new PP2011.

1)      The top of the Sinusoid when unit run from buttery is textbook exemplary and much more stable then it use to be before.

2)      The “fussiness” that was in PP2000 when it was operating from AC still there but it change characters. It dropped amplitude 4 times and become twice wider in bandwidth.

3)      PP2011 runs much cooler then PP2000 and much more silent

4)      PP2011 cuts off more HF then PP2000, I would estimate that I run my MF driver at 1dB hotter with PP2011

5)      PP2011 has higher dynamic range.

6)      PP2011 removes noise at lower frequency then PP2000 did.

This last characteristic I need to explain as it is something the I NEVER heard from any peace of audio before, there is a great chance that if you did not use properly sounding PP2011 then you do not know that it is possible.

Somehow, PP2011 can inject own contribution into the middle and upper bass and somehow very surgically to remove upper frequency noise from bass notes. What is interesting is that PP2011 cleans up the noise but leave the overtones absolutely untouched – that is enormously wonderfully and rare.  It is like you ask your cleaning lady to clean from dust your tonearm and cartridge an then you leaned that she did it and did not damage needle. Somehow PP2011 does it and to a much deeper level then PP2000 did.

Sonically it sounds like bass instruments have dryer decks and the sound more resonant because of it. The sound is not dryer, in fact it more moist but it coming from dryer instruments.  The feeling is remarkable and in way reminds a recording with closer microphone. Still, a closer microphone gives no full-body reverberations and in most cases it sounds immediately-impressive nit not no satisfactory. The PP2011 does all that close-mike effect  but still holds absolutely untouched reverberations, overtones and harmonics – absolutely unseen effect from my view.  This all give to sound a remarkable effect - I can with much LESS EFFORTS to zoom my attention to specific expressions of music without loosing respective to the whole sound.  The PP2000 was able to do it as well but the new PP2011 can do it to much higher degree and much more effectively.
