A novel way to massively improve the SQ of computer audio streaming

[Hauser]

A while ago I made a couple of Schroeder BNC cables for Dave-HMS using Neotech solid core silver double shielded when on sale at Parts Connexion.  They were a bit of a pig to build; required grinding the conductor and insulation to a point to marry the two cables at the connector.

I placed an order May 8 and haven’t heard anything from them ever since.  I have emailed requests for tracking information but have not gotten any reply whatsoever.  I have made many purchases from them and recommend them to friends, and everything has always gone smoothy before, including special orders for combinations of connectors and cables not shown on their website.

Last I heard from Ghent was May 15 - this was his message:

 

Thanks your new order.

Now I"m out of Shanghai, and will back for your order in couple of days later.

May i know what is the type of DC input for both 12V and 5V of your modified S100, is it 5.5X2.1mm or 2.5mm?

Hi, this does seem the easiest solution. Where do you get them from?

 

Hi- AudioQuest used to make some- if you are after build quality. You could try Amazon, eBay or boutique sellers (Music Direct etc depending where you are)

In my case IIRC, the  BNC/RCA came with the DAC, the 2 RCA F to RCA M most likely from kiosks at the local annual audio show.

If you can, please try the DIY Mundorf silver/gold cable recipe I posted if you haven't (more info here). They are the best DC cables I have heard, by far. I have wired EVERYTHING DC in my system with these cables.

 

I've now replaced all 3 of my DC cables out of my PH SR7 with these Mundorfs.

The first one was twisted pair, as per Nenon's original recommendations and, even from cold, this knocked my previous DIY star-quad Neotech copper (4x18AWG) out of the park - to be fair, the Neotech had an el cheapo screw-terminal barrel plug, which wouldn't have done it any favours compared to the Oyaide gold plated plug on the Mundorfs.

 

The second twisted pair Mundorf (from cold) beat my PH 6A silver (twisted triple, 3 x approx 19AWG, one used as screen wire). Not as dramatic an improvement as against the Neotech, but still a good step upwards.

 

For the 3rd pair, I tried the thinner 1.0mm dia (18 AWG) as a tight parallel pair (not twisted) as per Nenon's later recommendations. This time, with no JSSG360 screening. This also beat my PH 6A silver. By this stage I was getting burned out by burn-in fatigue (the Mundorfs sound good from cold, but need at least 2 weeks before they suddenly blossom). So all sorts of variables come into play over several weeks and I could no longer accurately quantify or relate how these improvements compared to the previous swaps.

 

I later added JSSG360 to the 3rd pair. This possibly made a small improvement, but hard to quantify. These were just 0.4M long, so maybe screening not so crucial?

 

So, I have no doubt these Mundorfs are fantastic. They have no downside in that they increase detail and dynamics whilst simultaneously decreasing glare and brightness. But I don't really know how beneficial are the following:

 

1. Value of JSSG360 screening for shorter lengths

2. Difference between the 1.5mm dia Mundorf vs the much cheaper 1.0mm

3. Difference between twisted pair and parallel pair

Hi Brian:

On thing that occurred to me in looking at Pink Faun's installation of the clock board is that they positioned their card right above the Melco's large DC-DC switching regulator and inductor, both of which get quite hot and both of which will likely have some EMI radiation. Not completely ideal, though I can see that they did not have many options for location. 

 

Of course it would be tough to bypass that noisy DC-DC buck converter as you would then need something like a 7 amp 3.3V supply, plus several other high current supplies at even lower voltages.  Now if only Melco would follow those DC-DC converters with a bunch of nice LT3045s for everything. But who would think of doing that?

@Nenon can probably find a way when he modifies his Buffalo switch. @RickyV, too. 😉

Well so far I failed to do that but @Superdad got me thinking. As I said before the buffalo board uses 3 voltages (3.3, 1.5 and 1v). I used a 2A lt3045 for each voltage thinking that that should be enough for the peak currents. But from a wattage point of view the board uses less then 2A at 12v = 24w. I got in trouble when I connected the 1V then the supplied voltage dropped to 0.7v (was 5v). I didn’t know why it did that but maybe the 1v regulator was overloaded because it could not deliver the current and that dropped the input voltage. Maybe I should revisit this with a bigger 1v lt3045 regulator. 👍

With that big, power hungry 16-port Broadcom switch chip you are going to need a lot more than just an LT3045 or two!  Plus you want that power to be just a few centimeters from the load.  Look at an EtherREGEN board. On side 'A' alone we have eight LT3045s. For two small, low-power Ethernet processors.  And we run them all close to their limits and provide them each with input voltage just 0.8V above output voltage to get away with that.

 

I was not kidding when I said you could easily need several a 5~7 amp supplies. I'd be kidding if I suggested you attempt it.

Thanks again for this recommendation Nenon. I have been intending to try this Mundorf cable for a while but I've been completing so many other small mods lately. I'll be sure to try it in the coming months.

 

I'm interested to know if you still use the JSSG360 shielding on these DC cables?

 

Recently my cables have been performing better sonically without JSSG360 shielding. I have now removed it from all ethernet, USB and DC cables. I had a lot of it😁. Removing it got rid of an annoying harsh digital edge to the treble. I can now listen to Milt Jackson on the vibraphone in pleasant ease 😄

Yes, I still do JSSG360 shielding on the DC cables. There is an audible difference with and without it. I prefer my computer and network DC cables with the shielding. But I don't do it on my ethernet and USB cables currently.

Perhaps the $20 a foot cost for 18 awg Mundorf silver/gold hookup cable is a bit much for some of us?

 

I also suspect there are at least a few people here that have never held a soldering iron.

Interesting 😁

 

The most recent cable I was testing this with was a DC cable between an uptone LPS1 and a ubiquity edgerouter X (my only router and DHCP server). I found a much more natural tone without JSSG 360. More ease and a more rounded analogue feel to vocals - less digital edge.

 

It's perhaps system dependent. I had previously thought it would be better whenever I put it. It definitely changes the sound wherever I put it... At one stage I had 8 layers of 4 x JSSG 360 on my USB cable.... Now I've gone full circle back to nothing 🤣

From some PMs I received today some people are learning as we chat :). Soldering a wire to a connector is not a handcraft that takes years to master, especially with the help of YouTube. Also, probably everybody knows a person who can solder. 

For the rest, there are always commercial solutions. 

 

Whatever you do, just don't go knock on @Superdad's door. If you need his soldering help, you might be better off doing this by mail after reading his last post 😂

The interesting thing about cleaning up electrical noise is that you get more focused sound with deeper soundstage, while leaving the noise in your system typically gives you a wider soundstage. There is of course different types of noise with different impact, but overall leaving some noise is not a bad thing and a good way to tweak your system. I call it "the good noise". That works especially well in over dampened rooms where all the the music gets sucked out from room treatments. I am a big fan of diffusers and lively sound. 

So yes - we can say it's system and personal taste dependent. Just like everything else in audio....

5-7A!!!  Are you serios?? 

 

i think problem not with the current limit but with the way of external regulator connection, if onbord regulators not disconnected from the load (reverse current protection can cause the problem). 

 

@RickyV How did you connect Lt3045 regulators to the BS??

Hi alexey,

i connect your regulators to the BS by first removing the switch mode regulator output coil which is in series in the output line. Then connect your regulator to the correct island of that coil. 

But when I get home I'll first have to look up the power consumption of the Broadcom chip that maybe a little to much and the startup current peak too.

A while back, I had mentioned that my star-quad Neotech DC cable sounded distinctly better without JSSG360. At that time, I was not aware of cotton tubing. I now understand that it's best to have some space between signal wires and screen (the experts here can probably explain why) and that is what the cotton tubing can provide. The spacing is a possible reason why some shieldings are more successful than others.

 

For those dipping their toes into DIY DC cables, much of the faff is in the JSSG360 part. But you could split the work as I did with my 3rd cable: First build the cable including the cotton tubing and then just live with that for a few weeks (or forever if you're happy with the sound).

Then you can slide the JSSG360 parts over the DC plug, without having to de-solder anything. I wrap PTFE tape as the insulation between the 2 braided shields and this saves having to get a heat shrink gun ("gas" PTFE tape is thicker and easier to handle than plumbers tape).

 

A good, and cheapest, supplier of Mundorf,  especially in the UK, is hificollective.co.uk. £56+VAT/metre for the 1.5mm, and £30+VAT/metre for the 1.0mm. HFC also do most of the other parts needed, like cotton tubing, silver solder etc, although strangely not so good on DC plugs. My 0.5M length 1.5mm Mundorf cost me slightly less than the same length of ready made PH 6A silver, although it has to be said that Paul's soldering and construction skills are far greater than my feeble efforts - my Mundorf did sound better though 🙂, even the much cheaper 1.0mm version.

 

HFC also stock Neotech and several others. The Mundorf silver/gold, rather like my recent Sablon 2020 USB cable, just sound so completely "right" that I have no intention of ever looking for anything else. But if I did 😈, then I'd be rather curious about the various Neotech silver, silver/gold and especially the "rectangular" silver wires.

You are right, Mundorf Wire 15.5awg Silver/Gold is $40 a foot at partsconnexion. $1000 for 25 feet is stunning.

I can say the sound quality improvement is something else -- I don't want to go into hyperbole but it's a big jump with dramatic improvement in everything. That's after a couple days of burn in, so hopefully further improvement.

 

Total cost for this is roughly $180. Each 8 port injector is $22, each U Green cable is about $5, the 2.1 mm male to male cable is about $8.

Belden brought its resources to bear to engineer a cable that is fully compliant with Category 5e requirements of TIA 568-C.2 using 18 AWG conductors to provide the required 600V TC UL 1277 Listing for routing through cable trays.

This included developing 18 AWG (American Wire Gauge ) conductors, a wider diameter than the usual Ethernet specification 22-26 AWG conductors (in the AWG system, a lower number means a higher wire diameter).

 

Apparently they aren't available in bulk, therefore we'll have to get a shorter one first and then find out if that were able to beat everything else out there. Finally we could get one @ 100 meters and then split that up among quite a few audiophiles.

Maybe simply get the longest one on Amazon and then cut it up afterwards?

Of course we could also get a VERY long one from Sablon Audio instead

Sometimes the wallet might be fat enough to try 24AWG Mundorf like this

We'll only need to connect 4 pins (i.e. #4 / #5 / #7 / #8) so it's gonna be like 64 Mundorf wires for 16 cables

 

 

More affordable options could be purchased here and they're even working great with the legendary SR7

For those DC cables between the boxes, we'll need stuff like Oyaide DC-2.1G

Standard power connector - 2.1mm x 5.5mm

BTW, the orientation of this breakout board might allow us to get things done without any crimping whatsoever but all 8 RJ-45 connectors still looked quite close to each other

We could also go for stuff like this but ultimately the quality of screw terminals might be questionable at best

Super adventurous ones could check this out and get a quote if you want
