Thanks, thats what I wanted to know - really says something about how good the HPLUN design is! 

Might have to buy one to find out myself.

 

Buy two if funds allow. You will be amazed with one but over the moon with two in series! I can even guarantee two LS-HPULNs over one. I’ll buy them from you from you if you don’t like them. But no more. All additional bets are off! ?

Does this help? ?

This is a balanced & isolated 230-12VAC feeder supply but it can be fed with a LPSU or SMPS as well. 1 Vf for best results in series. 3 Vf in single.

Is the red cable an ethernet cable?

 

No, it is the DC cable supplied with the AC-AC supply. Good quality silver plated wires. I intend to change them as soon as I have find the ultimate AC cable. That might take a while! ?

If you can get your hand on Furutech FA-220 OCC copper (14Awg), you will be rewarded with great dynamics and natural tonality. It is expensive and not easy to find. Don’t buy from eBay as they are fake.

 

Thanks for the pointer Moussa!   Furutech is always on my mind.

I finally got around to do one of my experimental DC cables. The Supra DAC. I used two cables and connected the drain wires of the two cables together in a loop. Red wires to +Ve and blue wires to -Ve. I kept the Kemet A750 caps that I used with Supra Cat 8.

 

 

Instant improvement over Supra Cat 8! More presence, more music glow, deeper bass, more ambience and clearer details listening to Halehan - Temple of Maia. Goosebumps present! 

For sure Supra Cat 8 will not go back! 

Remaining cables will have to wait until next week. Supra BiLine MKII will be next! ?

If this stuff really works, why can't a manufacturer incorporate this in the design of the dac and their ps?

 

Good question that I do not have a good answer to! ?

[Cornan]

I do not quite understand this nagging about 3 feets behind the speaker thing? I don’t think @Quadman have actually measured the depht of the soundstage. It is just his feelings dressed into words. I have my own word for it. 4D. It is more than 3D since it expands the soundstage (in all directions) without throwing in the vocalist back there. It surely feels like certain sounds emerge from behind the speakers. If it is 3 feets, 2 feets, 1 feet or not at all does’nt really matter. It just feels that way. Not everything in this hobby needs to be mathematical. It is feelings too! ?

Ive got a 4 pk of kemet a750 coming for the LT board . Are these the type you mean @sandyk ? I dont want to loose my deep end sound as i like it .

 

Trust me. You won’t! Just try it and see how you like it. I can almost guarantee that you’ll like them with the LT3045. In single or series.

 Not everybody uses ONLY  a HF detail challenged streaming service !!!

 Your solution may work well with Spotify for you, but may NOT be suitable for those who don't rely just on streamed services.

 

Well, that’s not true since I already know a bunch of people here and there that like them a lot with local content as well. Remember that this is a very simple and cheap tweak. Even if you might find a spot that is not optimal with the A750 there is great chance it will improve elsewhere IME.

I am actually starting to wonder if the HF detail you are talking about all the time is the one that creates the beloved 4D in my setup?

 As is putting a larger value electrolytic capacitor in parallel with their input.

If you need additional lower midrange warmth try using something like the "Elna for Audio"  capacitors across their input.

 

For the moment I have got all the warmth that I need. I do have a couple of Elna Silsmic II in the drawer looking for a job. I just have’nt found a suitable spot for them yet.

[Cornan]

So far I actually like the PANASONIC FC series Type A aluminium electrolytic caps 560uF better (and much cheaper) than Elna Silsmic II 1000uF together with the Kemet A750

560uF. However, I have only tried it on two spots and are planning to make more evaluations later on that included other brands as well.

 I extensively use Panasonic FC capacitors which have a fairly low ESR, but not as low as the Panasonic FM.

 

The Panasonic FM is already on my list thanks to you Alex! ?

This morning I got time to finish my next DC cable. The Supra BiLine MKII.

 

 

Note that this is a dual JSSG with two separate drain wires. The blue+red is connected to +Ve and the black+red is connected to -Ve and have their own shield AND drain wire.

 

Listening to Halehan - Temple of Maia again plus the brilliant Mike Dawes - Era where the acoustic and electronic mixed part and especially the hand drumming on the wooden guitarr interested me soundwise.

 

 

I also want to point out that my DC cable is NOT powering ISO Regen. This is what powers it. No long DC cables. The DC cable is located between the LPS-1.2 and the galvanicly isolated Spdif output of the Luckit BluWave board powered by IR.

 

 

Anyway, how did this new DC cable turn out?

Great, with a slight upper head over the dual Supra DAC. A more calm and relaxed sound in perticular. More natural. That’s where Mike Dawes - Era really shines. No noticable changes in the treble area. The bass is still very deep but feels more articular. More precise and quicker. Presence, 3D, 4D, ambience etc is more or less the same as with dual Supra DAC. I am just more relaxed and more eager to just listen to music.

The Supra BiLine MKIIs slight win over dual Supra DAC got me thinking. I just want to have good listen to the BiLine MKII before putting back the Supra DAC again with a slight change. I will put the red+blue on one cable to +Ve and red+blue on the other cable to -Ve. This way the two cables will be very similar, but the Supra DAC will have a drain wire loop plus +Ve and -Ve in separate cables and Supra BuLine MKII will have dual JSSGs in a single cable. Very easy to do so I might be able to do it tonight! ?

To be clear, you aren't replacing a DC cable, you are replacing the entire power supply. The power supply is the DIY one you've built, not the LPS1.2 which is simply serving as a presupply for your own supply. Since you are into building DIY power supplies which is great, take a look at the Salas Shunt. As a shunt design, will tend to smooth out current demand spikes. Will tend to make any conceivable affect of its own power supply cable less relevent.

 

No, I am just changing a DC cable with the Kemet A750 aluminium polymer caps that was there in the first place.

Here is the complete chain that powers soley the GI Spdif output of the BluWawe USB to Spdif board:

 

Gophert csp-3205II>Canare 4S6 DC cable>HPULN (3A LT3045)>LPS-1.2>Supra BiLine MKII DC cable>BluWave Spdif output (USB input powered by balanced 230-12VAC>Sigma 11>HPULN>LT3045 1A>ISO Regen). So the IR and Brooklyn DAC is powered by my own LPSUs and are not a part of this DC experiment directly anyway.

I hope that straighten the questionmark! ?

Uh ... anytime you attach an LT3045 to the end of a copper wire, I call that a power supply as opposed to a cable. Its an active device with electronic components and calling this a cable just confuses the issue. That's just how I think about things...

 

Well I see it like that too, but it is still a DC cable that matters in the end and it is still out of the box! ?

[Cornan]

Oh man! This thing just blew my mind just listening to the first 2 minutes to the first track (Encomium- Reverie) on Mike Dawes - Era! ?

 

 

The Supra DAC came back BIG time by the simple switch between the wires. Now each pair is connected to each pole and the drain wires of both cables are connected into a full loop.

 

Crazy! I guessed that it would make the Supra DAC more competetive against the BiLine MKII, but not ever to THIS extent! There are fibers and music glow in loads. Crispy high ends, smooth midrange and deep low ends. Air, 3D, 4D and everything else improved in a stroke of a lightning. No burn-in required at all. Just like a gate of heaven was suddenly opened for me to see all the bright lights, vivid colours and deep black colours. It really kicked the butt of any DC cable that I have ever tried before. I just love this crazy hobby! ?

 

I know what I want to do now. Change all my Ghent JSSG DC cables and Canare 4S6 into this! ?

Hey, where did you find this cable unterminated? I'll email the Supra distributer up the street to see if he can get some in, but wondering how much it costs per meter? 

 

I bought if from one of my favorite local swedish dealers

https://www.svalander.se/shoppen/kablar/kablar-i-loesmeter/digitalkablar

Svalander.se

 

I’ll guess you’ll find it on eBay or similar with some search. It was SEK60/m at Svalander and it is extremely cheap. Cheaper than Supra Cat 8 and much better sounding IME. The best DC cable that I have ever tried. Remember that this is not a JSSG. These cables have no proper shield. Just the internal drain wires connected into a loop and it sounds magical! ?

To get a good idea of the DC cables impact on SQ I changed my Canare 4S6 w/screw terminal DC plug w/o JSSG to butchered Purephonics with tripple CCC w/Oyiade plug between my balanced & floating 230-12VAC ps>LS-HPULN>LS-HPULN>Brooklyn DAC. No go! The sound was pushed back way too far. Including the singer. Feels unnatural. Next up dual Supra DAC with drain wire loop. Note that this is not a starquad and not a JSSG. Dual twisted pairs with nylon semi-conductice shoeld and a drain wire with a loop between the two cables. Stay tuned for more! ?

 

 

[Cornan]

Next up the dual Supra DAC with drain loop.

 

 

Boy what a releif from the Puresonic tripple ccc cable with Oyiade plugs in this spot! The gates of heaven was opened again. A breath of fresh air injected into everything. More music glow. More crisp. More presence. More air. More 3D & 4D but with singer in front. Fibers in loads. Wow! This got to be the best f***ing DC cable that I’ve tried ever! ?

Trust me! The Oyiade DC plugs is not better than chinease screw terminal plugs as long as they don’t fail! I have compared them many times and cannot hear a single SQ difference between the two. Sorry! ?

[Cornan]

I wish I could describe the SQ coming my way right now. Listening to Marian Hill - Unusual (MQA) constantly wants me to turn me head around. Feels here. Feels there. Feels everywhere!
