One step forward: ER +lpsu

Interesting to hear. I have ordered the Ghent dc cable after my purchase of the Lps 1.2.
But had not the possibility to try as it arrived 5 weeks after and in that period I get the MCRU and returned the Lps 1.2.
I sold the Ghent.
The MCRU comes with an Oyaide gold plated dc cable. Similar to the Ghent.

I just checked on the MCRU site. They sell DC cables.
Mine is:

MCRU Pure Silver Audio Grade DC Power Cable

It will arrive quicker, but more expensive vs Ghent. Mine costs ( the same as yours in your MCRU option 3) around 95 euros. There is also the Kimber at 65 euros.

I have 4 of the MCRU ones, well made cables. I also have a couple of Ghent ones (nb import duty un the EU). Can I hear any differenceā€¦ probably not. But MCRU/Ghent compared the thin black ones with molded on plugs that usually come with power suppliesā€¦ yesā€¦ difficult to describe, perhaps music sounds smoother might be the best description.

Perfect. Any idea about the plug size: it is 2.1mm or 2.5mm or the mix (one on each end)ā€¦?

They can do 2.1 or 2.5mm at each end, they can wire them centre positive or centre negativeā€¦just need to tell them when ordering.

Hi Gazza I got this. I cannot find if the ER in is 2.1 or 2.5ā€¦Anyone?

The ER is 2.1mm with centre positive.

You are referring of DC cables? If yes, you say the difference vs stock dc cable is very subtle ?

Yes DC, the diference between stock and up-graded is noticable. The difference between MCRU and Ghent is not so noticable.

Hi so I understand that on the ER side it is 2.1 mm; we all agree.
Now on the other end of the cable you mentionā€¦ 5.5 mm which is not an option on the mcru website for this cable, so maybe a typo from you? It can be only 2,5 mm (apart from 2.1 mm), and in fact since the ā€œER inā€ is 2.1 mm then I expect that on the other end (for the lpsu 1.2 ultracap) is is also 2.1 mm (because they are the same). So I need to order the 2.1 mm at each end of my cableā€¦

Yes you need 2.1mm plug at both ends for Ultracap to ER, in fact the Ultracap ships with such a cable included. Though as others have found a better cable can make a difference.

Hi Nestor,

From the Uptone site for Lps ultra cap:
A switch on the back of the LPS-1.2 allows for setting of the output voltage to 5V, 7V, 9V, or 12 volts. The input and output jacks of the LPS-1 are standard 5.5mm x 2.1mm size DC barrel connectors.

Here on the Ghent site. Itā€™s 2/1 5/5 as written

Features & Specifications

  • Oyaide DC-2.1G Canare 4S6 HIFI Power Supply Cable, Single(1pc)
  • Purely handmade craftwork, genuine material and solid substance
  • Cable: Canare 4S6 Star Quad, OD 6.4mm, 4 conductors x 20AWG/cond
  • Connector: Japan Oyaide DC-2.1G (2.1mm x 5.5mm) Golden-Plated DC plug
  • Solder: Lead free, Rosin Core with 3% Silver, 0.5% Copper and Tin

This may be important. For some time, I was unaware the the difference. I was using a 2.5 mm plug, and my ER would from time to time cut out, particularly if I was moving or changing wires. Went to the 2.1 plug and that solved the issue.

5.5mm is the length.

RE Ghent - one thing to keep in mind is those Oyaide plugs are about $18-20 if bought separately, so if your setup does change and you have soldering skills easy to reuse.

Hi FR, ok so I believe one dc cable plug has 2 characteristics: one is the 5/5 or 5.5 mm (which I do not know what it meansā€¦and anyway doesnā€™t really seem to have an alternative l) and the other which is either 2.1 mm or 2.5 mm which is the diameter of the plug. So I believe that by selecting 2.1 for each plug Iā€™m fine since 5.5 mm must be constant.
So basically I need 5.5 and 2.1 on each endā€¦

@Nestor_Burma the ER switch needs a 2.1mm plug and the length has never been discussed when I had my cables made so I would say that you are correct. I canā€™t help on the opposite side as my cables use a din type connection with a locking collar to connect to the P/S.

You may or may not need an earth cable. In my system even though I had the P/S made with a ground earth post when tested it was not necessary to use the cable. I think the Melco upstream of the ERā€™s does this.

I think you are right. I donā€™t know what means 5/5 , but as you said itā€™s 5/5 2/1 or 5/5 2/5.
So 2/1 is the size to choose.
