Congratulations, Uptone AND Sonore......

 

Thanks very much.  

[Cyrus]

You guys: You and Sonore (I'll add Small Green Computer also) deserve it.

 

I am thankful for what the Regen, Isoregen, LPS-1,  mR and now ultraRendu have done for me.

[mwhitak]

Second that. Thank you to Jesus, Andrew, and Superdad  for all the great work !

Well and of course John Swenson who engineers all these brilliant circuits!  These products would not exist without him...

 

Have a great weekend everyone,

Scary thought honestly.  What happens to UpTone if the unthinkable happened?

It is in routine social worlds, their ebb and flow, that the unimaginable is imagined (not me, but a strange, sublime, unusual Durkheim): You did ask the question though.

Really Jason?  You needed to go there?  What happens if you or I disappear tomorrow, or my house burns down?  (The latter not far-fetched in blazing California this year. )

I don't choose to live my life that way.  

Besides, John and I have a lot of products and a lot of fun planned for these years ahead! 

 

And don't worry my friend, with the advanced new 3GHz scope/analyzer he recently got--and the other test gear he is building--you are even likely to see the measurements you have been craving for.  Maybe we will even find the measures for some of the things most all of us hear but which the graphs have to date not shown.

Is it more important to have the LPS-1 on the audio bridge, or on the ISO REGEN? I have one LPS-1 and another linear power supply which is quite good but not as audibly good as LPS-1 and I want to know which to use on which device.

[jamesg11]

Last device before dac.

I'M NOT HEARING IT - a little advice from Uptone users, please

 

I'm at the proud owner of a JS-2 and and LPS-1.  Both have been in my system for many months.  Happy camper.  Thanks Alex, John S. (and Jesus on the microRendu assist).

 

Here's my setup: Topaz IT => JS-2 and to => my Exogal Ion digital power amp (powered by a 24V/9.2A Meanwell SMPS brick!--a very unique amp, with a very sketchy power supply for this crowd, I know.  But the gents at Exogal seem to know what they are doing).

 

The JS-2, in turn feeds my Exogal Comet DAC (which connects to the Ion via a proprietary employment of an HDMI cable--I said it was unique) and my LPS-1, which, in turn, powers the microRendu, which of course plugs into the Comet via a USPCB.

 

So here's my (first world) problem:  I decided today to listen "critically" as they say and remove the LPS-1 from the system.  I can hear no difference.

 

I know this is all system and ear dependent (I'm 55 with high freq. loss), but can someone tell me what to listen for?  The LPS-1 is supposed to "completely block the path of AC LEAKAGE CURRENTS".  But what exactly should I be listening for to determine whether I'm going to regret taking it out of my system?  

 

I realize one sensible answer is: if you can't hear the difference, that's all that matters.  Sell it.  But I want to give it a good chance before I do.

 

Thanks.

Are you powering the LPS-1 with an SMPS and is the -ve output of the SMPS grounded ?  Big difference for me and others.  Look for JSGT in the grounding thread.

[sockpit]

No.  I'm powering LPS-1 with the JS-2 (overkill!?!) on 12v (as Alex C. recommended).

 

I've read about the JSGT maneuver, but have assumed that by feeding the LPS-1 with the JS-2, I needn't lose sleep over that.

I have JS-2 and LPS-1 and am happy to power devices with the JS-2.  I think you can find another use for the LPS-1.

I remember reading Uptone saying it didn't matter what was powering the LPS-1, now it turns out you need some kind of particular jury-rigged power configuration to make it sound better than nothing?

 

Where I'm from that's called false advertising.

Question for you:  When you removed the LPS-1 from microRendu--for the comparison--what then were you powering the microRendu with?

Hi Michael:

Well neither I nor 1,500+ UltraCap LPS-1 users think that!  Everyone has been enjoying great benefit from the LPS-1.  But yes, it was discovered that the 80pF of total capacitance from some of the transistors used in the LPS-1 were letting pass a unique form of leakage from its stock SMPS charger. It is called high-impedance leakage and it is easily dispensed with.  Please see my full report about it here:

Hi Alex,

 

the JS-2, naturally ?

 

you see, I have always powered the lps-1 with the JS-2.

 

so I asked myself, could I live without the LPS-1.

 

after an afternoon of listening, I think the answer is yes.

[Superdad]

Well that makes perfect sense then since the JS-2 is a mighty fine supply in its own right.  Very quiet, low impedance, and very little leakage from it.  

And since you are using it to power your both DAC and the microRendu--which are joined together (via grounds) and are already isolated (via Ethernet), there are not even any power supply interactions (any two AC connected power supplies in a system--even linears--for a leakage loop).

 

Now if you were also using a ISO REGEN, then powering the DAC and the microRendu with a single JS-2 would be defeating the galvanic isolation of the ISO REGEN.  But that is another story...

 

So your report makes sense.  But power your microRendu from something other than a JS-2 and you will then be wishing for the LPS-1--or the JS-2!

I read through the "grounding trick" several times and it looked confusing and messy. And I was not able to obtain the parts needed to do it anyway (which weren't clearly specified). If this "trick" is so important it should be put in a manual with the device, and very clearly stated what is needed to be done.

It is not so important.  That was my point.  It is measurable but not very audible (though some claim it is).

You seem a bit upset about it Micheal.  And I know you have had some unusual difficulty with the second-hand ISO REGEN in your system.

Unhappy customers are not at all what UpTone is about, so I would like to extend our 30-day money-back offer to you on the LPS-1, even though you have had the unit since last October.  Please let us know if you wish for that.

Thanks,

ALEX
