I think lower chassis voltage does not give better sound in all audio systems.I do not why but Some audio systems have better sound with higher chassis voltage . I lost my sound for more than six month only for adjusting ac polarity for lower chassis...

Tesla Battery -> Tesla Inverter -> Purepower 3000 -> Audio System
using Tesla powerwall inverter before Pure Power , any experience? any idea?Thank you in advance...
|
|
Romy , you are right , pure power affects on wall AC quality, when a pp3000 is connected to wall ac (the TV not connected to PP3000) then the picture quality of my TV decrease. allways I use only one pure power 3000 and other pure powers are disconne...

Romy ThanksI had 6 pure power (230v version) since 2017 and now i have 4 pure power , the first pp3000 was faulty and it has the same problem that some users reported here (GSC) , the output frequency spectrum of first PP3000 had some extra harmonics...

Adrian Thank you for helpI think i should 100% agree youDid you compared class ab vs class a power amp when you connect them to pp3000?xandcgI have read about romy experience with paralleling capacitor with battery but it seems it does not help .I ha...

Please help me if you have any experience with PP3000.
now I have dedicated AC line (the line is three phase system ,phase 1 and 3 connected to home and phase 2 connected to my audio system) and a good cable replaced the building wire between ...

I guess it was shock for many GSC readers and most of us are thinking about this subject , changing from brain (high performance macondo) to heart (lovely Dunnoy) is very interesting subject in Audio.

I think discussing about "multiple systems (or multiple partner) vs one system (or one wife)" is quite different to what i said about two separate audio systems.I mean Two audio systems is not about two different sonic objectives. two different syste...

If I read you correctly the big midbass did not release the "intellectual tension/demand" of Macondo/Milq. Perhaps I'm wrong or oversimplifying but it seems to me that at least a part of your "problem" with Macondo is an i...

N-Set In Tehran properly setup audio systems are rare and most of the time we have not enough transparency to see what PP do with sound.some audiophiles in tehran believe the PP is not good (they prefer AC Line Filters to PP) because they had not go...

I have connected PP to 7 different audio systems and the result was quite different....

[quote user="N-set"]By "more alive" you mean artificially alive? In my case, PP resulted in more engagement, not sure if this is a result of aliveness. It does inject 20kHz all over the place that might add some "sparkle". I have dedicated AC line ...

I live in a big complex (6 floor - totally 200 apartments) and I can not have my own dedicated ground .
there are three phases AC Power in the building and one of them is not good, sometimes the AC voltage goes over 230v and ...

It seems the pure power 3000 diagram is like below :The battery voltage in new pure power+3000 is 72v (6x12v in 230v version) and the battery voltage convert to 330v by a switching dc to dc converter if i am not mistaken.What is your idea if we remov...

Amir,
Frankly speaking most of

audio aimlessness, and to a degree I feel that you are very much a victim of
