6) Ok, the first half elephant in the room – the dynamics. Believe me or not but PP3000 is more dynamic then PP2000. It was very sensible from the very first note that I heard from the PP3000.  I do not know what to say else about it.

7) The second half elephant in the room – dynamics is that PP3000 looks like provided even further HF attenuation. The upper MF aggressiveness, characteristic for electricity, looks like with PP3000 subdued deeper.  I would say I can run my MF and my tweeters harder with PP3000 to get the same level of comfort. I would say that I can do 1/3dB at MF and one full dB on tweeters. This is very good and it is an indication of PP3000 advantage. IT is very much might be due to the fact the I do not load PP3000 as much as I would do with PP2000 – with the same load but at near full capacity the PP2000 I am sure output more distortions then PP3000 at half capacity.

8) PP3000, probably because more HF attenuation, exposes more texture in sounds.  This is what I did not expected.




Hi Romy, I am a new user, I write from Italy.

Do you mean that Purepower 3000 "softens" the higher frequencies and the upper midrange?

This would be a good thing for me, I have B&W 803D speakers and sometimes I suffer their "aggressive"/"protagonist" tweeters resulting in a "monitor" signature in their sound. Source and integrated amp are Luxman D06 and l-509u, with very neutral sound (no warmness... "hi-fi - solid state sounding", but even no coldness nor surgical/analytical sound), cables (power, interconnects and two pair of peaker cables in "shotgun" biwire configuration) are Cardas Golden Reference (no extra warmness since I adopted the biwire configuration, which added a "transparency" I did not expect, since the single wire+jumpers solution sounded almost warm and rich in the bass; I liked that sound but jumpers made some other damages so I wanted to remove them; maybe one of the two pairs of speaker cables and the power cords still have to burn-in, I have them since last month the first, half month the latter). 

Do you think that this (1dB?) attenuation of high frequencies results in a stronger bass and cleaner mids ?

I'm going to buy a PP3000 without any possibility of trying it before, and I would like to know how "it sounds".

What you say make me think that PP 3000 is perfect for my system (I upload a photo)...can you confirm that?
