I do not encourage people to DIY the umbilical cord as it is difficult to make.  Many years ago we also came across one that was supposedly professionally made but overheated.  In another forum audiosensibility explained the component cost is 2/3 of the price, due to the high cost of OCC silver.

 

We do not endorse third party accessories or cables.

I fully agree, Peter, I would not recommend people thinking about making their own DIY cables either. It poses too much of a risk to the equipment.

How much SQ improvement are people getting by replacing the stock umbilical cord?

But in one of your earlier posts you said you will stick to your own homebrew, DIY, cables.  Maybe you are talking about other types of cables and not the Lumin umbilical?

Mine was noticeable but not earth shattering.  Was it worth the nearly $2k I spent?  Even I can't answer that at this point.

Some minor changes. But everything is incremental by the time you’ve reached this point in your system.

I have an A1 and semi-recently replaced the stock power supply with a Kenny Lau along with his umbilical cord. I did

find this to be a nice upgrade. I am wondering if the x-1 power supply offers any significant improvement for an A1 over the Kenny Lau. Has anyone tried that?

[wildsam]

Can the x1 psu be used with the u1 mini?

[Nicoben45]

The U1mini has a simple 12v power supply, when the U1 and friends has two different power inputs. So the U1mini can only be upgraded by an other psu that bring one 12v output. Good results at home with the Paul Hynes SR4t and home made dc cable.

Is this normal that on last 2 word display the brightness is dimmer comparing to the first word ?

 

Yes, this fading is a feature.

If I said I was using a DIY cable, that was probably the Gotham interconnects that were made by a part-time professional, not me, and the Gotham speaker cables made by myself.  I am using something branded (cannot tell you which) and more costly to replace the Gotham interconnect (that is now used with my 2004 AV receiver, and with the age of it I think the relatively inexpensive cable actually is worth more than the market value of the receiver).  And my Gotham speaker cable has recently been replaced by the Duelund Dual DCA12GA naked.  Only after I replaced the original speaker cable I used for years did I find that I actually made it wrong in the first place.  I am pleased with both cable upgrades.

 

The Lumin umbilical cord is more difficult to make because, I believe, there are a lot of wires (with a certain gauge requirement) squeezed into relatively small connectors.

No.  The X1 PSU upgrade is only compatible with Lumin U1 (large) / S1 / A1 / T1.

I recall reading several positive reports by users of S1 and U1.

 

If you are willing to try a more neutral sound signature, you may also check out the T2.

Should have said "bare wire" instead of "naked".

We are working on Tidal Connect and Spotify HiFi, but these are not finished….

 

Any chance of a rough estimate for when this will be available?

Thanks.

I wouldn't call chopping off - with or without fading - the title of a work, a "feature". But...whatever.

 

(The display on the Lumin is a big bugaboo with me - I leave it entirely off.)

[BlueSkyy]

I leave my display off entirely as well but not because of the fading feature which I understand and actually like because it "bows out" to the track count and track timing circle on the right.  I keep mine off because this sort of display technology is prone to "burn in" where segments that don't get used much begin to fade away permanently.  I wish there was a maintenance function that you could invoke that would light the whole thing up so that the faded elements could be rejuvenated.

lumin  u1 mini break-in,.  

 

I ran my stock u1 for 1 week before I gave a good listen.   I have a uptown audio Mac mini - with js-2 power supply.  it took a week before my lumin u1 mini beat it.   Now if you upgrade to a sbooster power supply.  The u1 mini. really steps up to a huge improvement!!  Bass is better  soundstage,  smoothness.  many more area.  But this all depends on your system.   

 

Im running a lumin u1 mini with sbootster.   Best streaming sound I have ever had.

Thanks,

I like to upgrade to sbooster, but I don’t know where to buy in my country .

I live in Jakarta- Indonesia .

@wkliehi, I have noticed that during the upsampling from FLAC file (lumin u1 mini ) to DSD the sound diminishes and have to raise up the volume. Is that normal?

[wklie]

That's related to how your DAC handles DSD.

Do you consider it a problem of CXA81 amp/DAC ?

no: DSD always plays 6db lower than PCM
