New John Kenny Power Supply....

Funny you order from yourself.

 

I had the same thought.

 

The fact that DA went from "I just discovered these products" to "JK is a genius" to "I just ordered this product" in the space of a few posts makes me suspect that thread is just JK or his sock puppet trying to get free publicity for his products.

Batteries are all "fully" floating power supplies. They have no leakage currents because there is no ground return.

 

Thank you, and in a system which already has multiple different chassis and safety grounds in place, the use of a battery supply in the mix might then have a positive effect on sound quality by minimizing or eliminating potential for ground loops or AC leakage?

To answer @plissken (even though he steered right around my question) my DIY Eneloop supply actually sounds significantly better, more revealing, better low-level detail, greater dynamic contrast, better sound stage focus etc... with the aforementioned penalty in terms of practicality ease of use: every 6 or so hours of run-time it needs a recharge, which does get old though not completely cumbersome.

Is the above indicative of me having identified or solved some sort of "problem" as @plissken referred to it? I don't know, but it sounds better than an iPower despite that need to recharge.

Watching closely to make sure DA isn't JK.

I think you answered my question about a battery supply needing a chassis ground with 3 questions? 

 

No, I'm asking you what problem you currently have and how you know.

Yes and I am powering the battery with the LPS-1.  It really is a fantastic setup. It plays all day when I am home and have had no issues whatsoever. 

 

And what is driving your LPS-1?

 

What would you say if I told you the LPS-1 doesn't eliminate any 60Hz AC leakage?

What steps have you taken to see what is going on with your setup and have you taken anytime to learn how to assess and measure the output coming out of your DAC?

Is it tricky to catch previous banned members who then can use a different alias and VPN? Anyways it will unfold one way.

The Meanwell PS that came with it.  I wouldn't say anything because as I said, the science to all this is well beyond my brain.  I emailed John about using a battery to power the uR because I recalled reading somewhere on these forums last year posts of people using batteries to power their mR's.  I tried it and love it so far.

For most people the answer is none. Why do you care so much what other people do?

Yes, you answered my question with 3 questions, please accept that reality.

No, I didn't state anywhere that any "problem" existed, I said I built a DIY battery supply out of AA size Eneloops, because it was easy and fun to try and would eliminate the only SMPS in that set-up.

Sure enough it sounds better with the battery, furthering my interest in such possibilities.

Good point, puzzling to say the least.

Learn how to assess and measure the output of my DAC? Meaning listen to it with my ears?

[Digital Assassin]

I can state with absolute certainly I am NOT John Kenny, I have NO AFFILIATION with John Kenny, and I have not ever

spoken to John Kenny,

 

I only have been aware of his products via reviews, period.

Posters start threads about new products every single day here.  Get over it, as much as you would love to believe I am John Kenny, move on.

I would say you are 100% wrong.  And later today we will be posting graphs and pictures to prove it (over at that other hangout where your pontification filter is turned entirely off at all times Jinjuku).

It's just a question and I'm not owed an answer.

If your approach is to not understand what your system is doing in your room that's perfectly fine.

No problem.   Amir was not measuring leakage.  But I won't spoil the tale here.

What do you call the 60/120/180 etc sprurie? Why is it 60 Hz? 

 

When is 60/120/180 fundamental and even/odd harmonics not AC leakage or capacitance of some kind? Does the LPS1 prevent AC loop?

What is your interpretation of this?

Why would it eliminate leakage in a loop that doesn't involve it? Also why would you draw a conclusion from a single graph? In the absence of a schematic, the graph is meaningless.

Alex said it would for starters that it would prevent AC loop through the regen. 

 

I didn't draw a conclusion from an unknown. I know the layout of equipment involved and it's common of a typical setup.

You posted the graph, at the very least post the schematic.

I don't have to. Alex said it would stop the AC leakage through the ISOR. It doesn't so far regardless of system topology unless Alex shows us something else. 

 

Isolation means 'To Isolate' ergo break the path of least impedance.

Ok then you are  posting irrelevant and out of context graphs that have absolutely zero meaning without a schematic.
