I have connected My Audio Note DAC 5 to EAR HP4 Headphone Amplifier and I hear the sound from My Sennheiser HD800. the Source is Computer .
Sennheiser HD800 is not easy load for HP4 and i think HD800 is very very bad sounding Headphone.

Jarek, When you say "not 50 Hz hum" it reminds me very much of my troubles I had with my Pure Power 1500 -- (before it "blew up" and needed to be repaired ... ultimately replaced with a new PP 2000 plus by Damien) -- but in any regard, the hum was ca...

In regard to the noise issue I had with my Pure Power unit in the past, I never noticed it with my tuner or other components, but I mostly listen to the phonograph. In particular the Decca cartridges are incredible as antennas and seem to pick up all...

Paul. GSC = goodsoundclub I have worked with Richard (pure power owner) and i know the problems of customers but i think paypal is a good way to shop from Richard. Ask Richard to send you video from the unit before paying to him. Recently 3 or 4 pure...

Either my ears have gone bad or I must be the luckiest user of pure power regenerators. Have been using three for four months now and am still bowled over the improvement in my system. No matter what time of day I listen it sounds superb, but I do no...

OK, here are my thoughts for today. Below is a very simplified schematic of Pure Power 2000 regenerator. I do not know if it is, but I think that it is how it works. I do not think that it is different from any other on-line generator. At the li...

This subject of waiting is very interesting with PP and it is what I am contemplating now: to get the new PP3000+ or to wait until ther new units mature a bit. I do like the sound of the new generators, this is given, but I do not see why the same s...

[quote user="Romy the Cat"]I am very sure that if you buy directly from PP then they will not make
you to pay until you get the unit. I very much do not advocate buying from PP
or from any other manufacture. [/quote]Not correct. However, I am glad ...

[quote user="steverino"]It would basically require discarding the original unit and sending out a PP plus in return in many cases.[/quote]Wow, you really know how to twist the knife. I only WISH they would make good on their promise to send me a new ...

Now fully five years after the original PP2000 was in my system, then subsequently stopped working and was sent back for repairs to the manufacturer. An unfortunate series of events involving the Chinese subcontractor resulted in the company contract...

[quote user="rowuk"]Alex, I have a APC RT UPS which is a regenerator and UPS in one. I use it for on site recording as you never know what you get from the wall socket. Dimmed lights, PA and all sorts of other devices like air conditioning and refrig...

With interest I read the posts about the mains / power and the effect on hifi gear.
The conclusion why and how electricity thus have an impact and the overall sound of our system is influenced by it is actually quite simple.
Generally the mains is ...

RowukI have fully read all pages of this topic (mad mad mad electricity) two times and I know good sound does not come from pure sinewave .I should say I am here (like a student) to learn more and I do not like spread my in-complete BS ideas here.I r...

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...

I am bit confused with that new report. Under no circumstance I would defense Pure Power, nor anybody want my defense, but the reports I hear juts do not makes sense. If look like Pure Power grade for extra 30% or 50% power with new units, I do not r...

I sympathize with those who were caught up in the financial problems that pure power had when one of their salesmen went rogue and attempted to steal their product, which lead to a long court fight which they won. Obviously this didn't help th...

Both ABB 20KVA UPS and Pure Power 3000 are IGBT transformerless UPS and the AC output of them is not perfect Sinusoidal .like Pure Power the ABB is also sensitive to AC quality.ABB 20KVA UPS does not isolate Neutral line but the Pure power 3000 isola...

[quote user="joaco"] Romy ; One question for you ; Does the pure power unit raise its temperature (gets hot) when youre using it ? or is it always cold ? I do not know what kind of IC they are using but I suspect they are "new generation ones??" I wa...

Amir, this is the most popular thread at GSC for a reason. While most people don't give bad electricity a thought, there are obviously plenty of audio people who are looking for answers to these questions. Since my AC provider went "Smart", the AC wh...

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...

I can’t stress now much I am fallen in love with my new PP2000. I was playing it today all day and can’t not see any single thing that I would bitch. I perhaps is missing too much the sound of proper electricity but my feeling is that the new uni...

[quote user="Romy the Cat"]partially because we do
not know what certainty what constitute “electricity problems” and how sound related
to the thing that we do know about electricity. [/quote]I also do not know.I think Pure Power 3000 is not just a...

[quote user="Paul S"] So I'm wondering how things are going for the bold explorers who forked over their expectations for a whack at the PP2000. Have the things turned out to be Plug and Play along with All That, or is this yet another case whe...

[quote user="rowuk"]The subject of line filters and uninterruptable power supplies is one that has been pretty free of amateur DIY myths. No one seems to know what makes one sound good or bad and when. The subjects getting attention are IsolationReco...

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.
I desired to use just records and connected all amps, preamps and phonostage to ol...

The way it is described, I have to agree about taking the Pure Power to a trusted local repair shop to get it scoped out.I will just say again that repairing the Pure Power seems to fix the problems, for those who have been able to get their unit bac...
