In this application don't you want the aural jelly and not oral jelly?

Or maybe we should forget about logic in that Silanna chip.

 

Yes, you will probably sleep better if you do. 

 

Though of course ISO REGEN is about much more than just that.

Nah, it’s just voltage divided by current.  

 

I’m going to begin my 8 hour horizontal meditation now.  Ohm....   zzzzzz.....

The upper one is a Dutch Lush^2...

 

Wow, your camera really had a hard time capturing that gloriously ugly "Phasure-yellow" color of the jacket that Peter chose to perfectly match his web site.

My audio chain is UltraRendu > Lush^2 > ISORegen > Light Harmonic Lightspeed > DAC

 

Like @austinpop, I expected to place the Lush^2 between the IR and the DAC, but was surprised to discover that I prefer it between the UR and IR by a considerable margin.

 

That's cool.  Perhaps now might be a good time for @PeterSt to at last burn-in and give a listen to the ISO REGEN/UltraCap LPS-1.2 bundle (that we traded to him for two Lush^2 cables months ago).  But then he might go mad with more combinations to experiment with!  

 

Of course I truly understand the limits of available time, as I myself have never had a chance to even once change my Lush^2 from the configuration it shipped in way back then (the paper says it shipped: A: B-Y & W-R,  B: B-Y).

 

From the above bi-continental experiments of the past couple of days, am I correct that Peter et al are now most preferring 

A: B-W-Y-R, B: B-W-R ?   Or should I go to the discussed and pictured A: B-W-Y B: B-W ?

I'm so confused...

Next the Lush 2 was re-configured to the default A: B-W-Y-R, B: B-W config.

 

I thought that the current default config was A :B-W-Y-R, B: B-W-R.  At least that is how it is still listed in the first post of this thread.

I tried PNF and later PNF^2 but the clarity and transients of the default A:B-W-Y-R, B:B-W-R can't be beat musically with both cables before and after the USB REGEN.

 

Of course you mean ISO REGEN (not the original USB REGEN). 

Now Larry, after all your tweaking of my NUC this past week, I'll have to go back and listen to the default Lush^2 config, PNF, and now PNF^2.

Crazy how different the first two sounded (from the way Peter shipped my cable so long ago: A: B-Y & W-R, B: B-Y) when I tried a couple of weeks ago.  Initially they both sounded very wrong to me, yet after a while they made more sense (in both senses of the word).

 

Fun stuff.

I wish my favorite Linux geek would stop foisting his weird LUSH cable configuration syntax upon us! 

I’ve owned a Lush^2 for over a year and it was only a couple of months ago that I fully grocked the popular nomenclature for the jumpers.

OK, like @lmitche I didn't leave the latest config in place long enough.  I decided to try again, and lo and behold it is better than A: B-W-Y B: B-W-Y.  It did take a while to show itself.

 

Hi Colin:  

So which config are you liking now?

And when was A: B-W-Y, B: B-W-Y discussed?  I thought @kurb1980's "Cubed" config was A: W-Y-R, B: W-Y-R.  So hard to keep up with you guys!

A: B-W-Y, B: B-W-Y was @kurb1980 previous favorite, which several of us tried and liked.

 

Since he couldn't "kurb" his enthusiasm, he continued to experiment, identifying A: W-Y-R, B: W-Y-R as his new favorite. I agree with him, I like this config better too.  So I said bye-bye to BWY-BWY   and am now enjoying A: W-Y-R, B: W-Y-R.

A: B-W-Y B: B-W-Y was Kurb1980’s previous config a couple pages back before JSSG360 cubed came along.  I liked that one better at the time but after reading Larry’s post that he hadn’t given it enough time in place, I gave it another shot and sure enough, it was better.  

 

Thanks to you both.  So I guess I got Kurb1980's config wrong and what I quoted as his is actually the latest one you are enamored with.  That's good because that it what I had written down on a Post-It to try next.  A: W-Y-R, B: W-Y-R.

... and I guess I just assumed it worked with VBUS off because my tX-U does, and it definitely sounds better that way.

 

That’s because the ISO REGEN uses 5VBUS on its input (which we dedicate an LT3042 reg to turn into 3.3V) to power the upstream side of its Silanna high-speed galvanic isolator chip.

The SOtM tx-USB units do not offer galvanic isolation, so they do not require VBUS. That lack of isolation may also be why they sound better when VBUS is turned off.

 

As far as VBUS on the output side, that is entirely a function of the requirement of a given DAC’s USB input stage.

My system is UltraRendu =>Lush^2=>Iso Regen=>AURALiC Vega. My Nordost USB cable works consistently but not the Lush^2.

 

Try putting the Lush^2 on the output side of the ISO REGEN—between it and the DAC—instead of before it. 

The Silanna galvanic isolator chip at the input of the ISO REGEN is not always tolerant of out-of-spec USB cables at its input. The ISO REGEN’s output is happy to drive any cable though.  

 

I use and greatly enjoy the Lush^2 in my system. And it is about the only cable that I prefer over our own USPCB A>B Adapter as the connection to the DAC after the ISO REGEN. 

So I suggest you turn the USPCB around, using it to position the ISO REGEN at the output of you ultraRendu—and then run from the ISO REGEN to your Vega DAC with the Lush^2.

I bet it will work and sound great for you!
