It just says DC cables being used as DC, network for network, and that you've already converted a bunch of DC to Gotham. So it sounds like you're just using the Supra for ethernet?

You can also put two (or more) in parallel to both reduce noise and increase current.

 

Both series and parallel reduces ripple to a minimum.

Series is simple. Parallel is not as simple but this post might help you to acheive it if you do not want to buy Stammheims HPULN or HC-HPULN.

 

 

Also Alexey have a parallel LT3045 in the pipeline. You just need to wait for it!

Ok, well I was hoping at some point there would be attempts made to really compare and hashout cable choices and construction to get to the heart of this, but it's become more like a Choose Your Own Adventure and already stalling out. Too bad. This line of inquiry had real promise. Hopefully Swenson/Superdad will pursue this.

Already parallel! 

Alexeys = 2 LT3045s for 1A

HPULN = 6 parallel for 3A

HC-HPULN = 10 LT3045s parallel for 5A

Look on LT3045 data sheet, see SET pin on chip used as reference to parallel chips to work together.

Yes I know. I use them all! ?

Each LT3045 is 500mA and not parallel. Alexey is coming with a 1.5A version soon though.

To get the 500mA boards (or 1A) to match you’ll need to wire them according to my link above.

Why do you think comparisons were not made?  A disciplined process was followed. Tests were performed on multiple systems. Outcomes are clearly communicated. What is missing?

 

Agreed, John and Alex having a great track record of adding value and insight into CA solutions.

And if none of those suit your needs, you can always make your own PCB.

I just got some bulk Supra CAT8 to try this out, how are people wiring this for DC cable? There are 4 twisted pair, each individually shielded. Is it just two pairs "-" and two pairs "+" or something interesting like all solids + and all stripes - ?

 

Boy is this stuff stiff though. The shielding around each pair is VASTLY thicker than the usual foil shield you see, which is usually  a few atoms thick of aluminum deposited on mylar. This actually looks like heavy aluminum foil bonded to the mylar.  The foil part is on the outside, so the foil from all the pairs touch each other. There is a sparse weave of wire around this bundle, which as far as I can tell is not an extra shield, it is just a "drain wire", an easy way to solder to the shields and tie all the shields together.

 

Anybody know what the material is around the wires? I could not find that out. It seems very soft, it might be a foamed material.

 

I have the setup to run an impedance VS frequency test, I can compare this and a Canare cable.

 

It might be a couple days before I can work on this.

Wiring brown pair to orange pair for +ve and green pair and blue pair for -ve. I tried all solids and all whites but didn’t sound as good imo. 

 

So you’re saying that all of the foil from all of the pairs should be twisted together for the JSSG and not just the outer web?

No, the outer web IS the way to solder to the shield, that's what it is there for. The foil is aluminum which is VERY difficult to solder so they add the outer wires made out of stuff that IS easy to solder to. The web and the foil is in contact all the way along the length of the cable. So you just need to solder to the web when connecting to the shield.

[charlesphoto]

That's what I thought. Is it enough to to just twist vs solder?

Is this is the same cable they use for your old favourite, their Supra USB Cable?

Must admit I am also confused with the feedback here as DC cables for DC seems to be contrary to ethernet cables for DC as per what we are investigating here.

Good to see that John is now testing Ethernet for DC so hopefully some good clear feedback soon from the master of clear comms!!

Will be exciting if this SD Card player beats my audio PC here at home when i get it soldered up with reclocker and power supplies.

Sorry for the long diversion but anyway the thread seems to have moved away from cheap POE setup to networking and more expensive connectors!!

I have been checking on that thread occasionally to see whats developing. You got to hand it to the folks there with their endless experimenting and discoveries. Sounds intriguing that a cheap SD card player can outdo your audio server.. and I keep meaning to order one for the fun but have too many other pots cooking.

Thanks for the report @sligolad

 

.. sorry bit off topic..

Been checking here for several weeks now and I am really surprised no one has commented on the single most bang for buck upgrade you can add to your system when using the ISO Regen.

In fact I think it would be a perfect add on that should be offered with all ISO Regens at point of sale.

 

If anyone has followed Rob over at US Audio Mart (seen you there often Alex) you will be aware of the discussions on the serious uplift in sound quality you get with just adding about $10 of cable between the power supply and the IR.

Its basically a quick and easy cable snap in and then just sit back and be blown away by the greater separation, low frequency dynamics and overall amazing depth to the music never heard before, i listen to Red Book files...its all there!

 

For those looking for an explanation on how adding cheap cables into the power in on the IR could make such a difference I have to say this has me dumbfounded and I was a complete skeptic, the low cost and easy install was the only reason i tried it.

 

Its basically adding a CAT7 cable with passive POE ends to carry the DC between power supply and the IR, when you connect up the 2 pieces just stick the power supply in the female jack on one end and stick the male jack on the other end into the IR and sit back and be amazed.

 

Some links below:

POE Ends

CAT7

I used all the components cited in the original post and I am blown away by the results. If I could describe it in one word it would be ‘air’ on almost everything I listened to. What a monumental beneficial tweak. Only in a place like CA Audio do you find something like this. Bravo.

You do realize that we’re just having fun bodging together bits of cable to see if we can make our hifi’s sound better, and not trying to perfect a self driving car or some such mission critical project? Plus the parts are cheap, and it’s only low voltage so not much danger involved. Computer audio is a fast moving target. You can wait, or you can do. I’m glad I didn’t wait and am enjoying the best sound from my system yet.

+1 It is important not to loose the fun of it all. That is the key however you do it! I trust Larry whatever he finds to improve on his own setup. Even if it do not improve on my own setup I do trust his judgement as if it was my own! By real life experience I know that certain changes are dependent on where your music is coming from. Tidal streaming is not the same as if it is coming from a local server, HDD or NAS. If you want to enjoy them all you’ll have to know that everything do matter! ?

That's a hell of a strawman. I was 'doing' this tweak before it showed up here. Glad you got great results. Maybe you could have had better results. We won't know. Enjoy.

Hi John, if possible can you also add an IBRA Cat7 ethernet cable as well as (based on lmitche's experience), the Gotham Audio cable he used? I'm sure some of us would be willing to send you samples if needed, since excellent results have been reported from all three.

Cornan and Charlesphoto, many thanks for your support! You are right, this is just a hobby, a pleasant way to pass spare time. There are no right or wrong answers. Let's hope others can learn to keep that perspective.

We have no room for your attitude here. The ends don't justify the means. We mean to have fun and enjoy each other's company. If you don't like it, please go back to where you came from.

Supra8 (+JSSG) 1ft long wired brn/orn pairs +ve, rest -ve as a DC cable, Uptone LPS-1.2 to Sonore ultraRendu:

 

I am impressed with it as it slightly edges out my silver plated custom cable - it as if the music has been turned up a notch- better dynamic range?  lower noise floor? I don't know, but in either case it is an excellent tweak for little money!

Have fun!
