ISO Regen performance Improvement Cheap!

Cornan:

 

What do think is the largest gauge of wire + Kemet lead that will fit into the LT3045 screw-in terminal? I want to order some better hookup wire than I have been using, something like Neotech Solid, maybe 14 gauge or so?

 

Thanks!

What is an Sbooster 'single unit'? And how did you try it 'after' an iFi iPower?

I think 14awg is somewhere right if you do not want to sweat too much when fitting the wire into the screw terminal. Neotech solid is definately a good choise IMO!

Tip! When using solid wire you can insert the wire and tighten the screws (and loosen them) before inserting the Kemet. It will flatten the solid wire a bit and make more room for Kemet’s pins.

I'm using 12awg Neotech solid hook up. 12awg will fit, and you could slip a Kemets lead in the side as well but it's tight. If I had to do it again I'd go with 14. The Neotech sounds much nicer than the 12awg Romex I tried, but give it a couple hundred hours burn in.

I will gamble with a game of audio related Russian roulette (especially when Tubelover2 is following this thread very closely apperently almost talking to himself at US Audio Mart) and thinking out loud here. How about combining JSSG360 and Kemet’s by connecting the two shields with a Kemet in series inbetween the shields (not parallel), letting no DC current to pass between the two shields. In my mind that could be an interesting experiment atleast in my point of view. Interesting to see how much DC currents affects DC. Surely Tubelover2 will disagree, but who cares? Not me anyway! ?

[Cornan]

Another interesting thing happening at US Audio Mart is Tubelover2’s amazing audio flag find at the point when doing a dual Cat8. Sorry, but is’nt that what I did some time ago? Just saying! ?

[Cornan]

Audioflag 2. Tubelover2 wants to try Stammheims SD-HPULN. Wow, he’s too late as usual!

Been there. Done that! My guess is that he will try to claim Kemet’s next! ?

Look here https://www.computeraudiophile.com/forums/topic/28056-linear-power-supply-for-brooklyn-which-one-youve-ever-tried/?page=2

Go Down a little.

The SBooster is a kind of passiv filter for SMPS. 

I tried the iPower 9V SMPS to the Sbboster unit and then going to POE to a TP link switch In my second system.

 

1. I tried the iPower alone

2. then with POE 

3. with iPower and the Sbooster single  Unit

4. With iPower  and the SBooster single unit and POE

I clearly prefer the 4. config.

You are 100% correct and here is why:

Linear Technology LT3042/3045 regulators are completely unlike any other on the planet.  Their very high PSRR and ultra-low impedance across an extremely wide bandwidth mean they are “faster” that any capacitor.  So putting big caps on their output (even low ESR 560uF ones like Cornan is using everywhere) is totally the wrong thing to do.  There is no cap that has a lower impedance across a wide band than what comes right off the 3042/3045.  For any other regulator sure.  But for the LT3042/45, anything more than the required 10uF “stability” cap is technically going to reduce their performance.

 

And the above jives with your report about better results adding a Kemets to an original LPS-1.  That model utilized the 1 amp Ti TPS7A4700 regulator (the LT3045 did not even exist when we were doing the original UltraCap design).
 

 

I just took the Kemet caps off of the output side of my Lt3045, and yes it’s better. I had a bit of the “haze/grain” too, and while very natural sounding just not as good dynamics as no caps on the output side. Using Neotech 12awg teflon hook up wire.

Do you still have one on the input side?

[rah50]

Thanks Cornan & Charles!!!!!

 

14 gauge Neotech solid  ordered.

Yep, two. One on the Oyaide at the output of the LPS-1 and one on the input to the lt3045. Both done Cornan style with the cable soldered partway down the legs of the Kemet caps. I took the spare two caps I have now and added them also Cornan style to the cables of my NUC and external 2.5” usb drive (both fed by HDPLEX 100). Everything sounding amazing.

He should get over the whole poe thing and just go with some good proper gauge separated wire.

I was reading the POE thread over at USaudiomart Yesterday and my bloodpressure went up and the reading about Cornan and Charlesphoto and others made me very sad.

I sincerly hope tubelover2 will stop his personal attacks and concentrate on the Audio related things, that he is good at.

I could care less about him. I'm enjoying the most amazing sound and music with my oversized solid 12awg Neotech/Kemet/lt3045 cable. Let's not forget the bigger the gauge, the less the resistance, etc. It really sounds huge and meaty, and better without the Kemet's on the output of the 3045 - big fat, short pieces of wire soldered with Mundorf Supreme to Oyaides is where it's at imo.

Yes, had same experience 2 days ago. More detail in new DIY LPSU listening report.

P.S Also input side too.

Results from first of 3 cable replacements:

 

Gotham GAC-4/1 JSSG360 is much better than Supra Cat8! 

 

[Forehaven]

I've upgraded my DC PS lines again, replacing Canare with Gotham.  All finished exc. the cables inside my PC...And I added a Cisco router at the same time.  I also eliminated my 'LT3045 metal box' and put all LT's in line and close to devices.  jAnd added Kimmets to the inputs only on all the LT series boards. 

As I told Larry, "Holy Shit"!  What an improvement, far greater than what I was expecting.  More analogue, resolving and musical now.  Great upgrades guys!

@Forehaven, for clarity, isn't it true that you have either sigma 11 or lps1 power supplying the lt3045 cards? 

 

If true, in this case, you have done what I did here, only using the Kemets on the input side of the lt3045 cards from non lt3045 sources.

[John769]

regarding Kemets on the input side of LT3045 boards, do you put them on the input of the first or second board when using two boards in series?

Kemets on Input side of 2nd LT3045 is on Output side of 1st LT3045. Caps not recommended on Output, so probably not good idea in series configuration. Prefer full bandwidth thru both regulators.

Kemets still good on output for other lower bandwidth regulators (non-LT304x), as Larry say, and my experience.

Yes Larry.  Sigma 11 powers my two LPS 1, which then powers the USB card and the SU-1.  Sigma 11 also powers LT's for the AQ USB and the ISO R and Sonndheim's reg. for the HD.  Sigma 11 only to power the router and HDPlex.

 

I hope to tackle the rest of the PC's cable swap before I have hand surgery again.

For anyone’s info who is using these fake sigma 11 power supplies, i use them too, original are from https://www.amb.org/audio/. 

The big capacitor on the right is on the output of the power supply and not in the original amb schematic!! Mine came with Hover caps, i removed both and replace the left one with mundorf ag cap. Try it, it is a nice improvement.
