For comparison the $10 25MHz Crystek 575s we use are running about -108 to -112. Compensating for the 2.5 octave difference that -110dBc/Hz average equates to about -119 if that 25MHz Crystek was a 10MHz clock.

So why pay $150 for just unneeded long-term frequency stability. For these applications it does not matter at all if the frequency drifts a tiny bit over time!  

 

Absolutely.

FYI - they really aren't THAT expensive IMHO and there's only one £195 Duelund CAST Silver inside each Extreme

13 pieces of Mundorf MLytic AG were placed next to Duelund and obviously they're quite affordable, and then we could find 2 more nearby but they're still inexpensive

There's a much larger one on the other side that might look more like Mundorf MLytic HC, once again it wouldn't cost too much in the first place

Duelund CAST Silver seemed to be a solid performer, it's just almost nobody was interested other than Taiko Audio

Duelund CAST Silver may well be acting as a bypass capacitor, which could deliver most of the sonic benefits allowing  MLytic to be used elsewhere.

In the review it states the Duelund capacitors are $1000 each, hifi collective $210. Quite a difference. Are they the same specification?

The MSRP of the Duelund CAST Silver Capacitors used to be very high. Here is an example of one value above 0.1 uF - 

https://www.partsconnexion.com/DUELUND-77035.html - with MSRP of $1,499.95.

 

Duelund created its own competition when they released the Tinned Copper version. It was supposed to be a more affordable option to the silver and the hybrid (copper/silver) caps. It turned out many people (including me) prefered the tinned copper version over the copper or hybrid (copper/silver) version.

Here is a review that ranks the hybrid less than the tinned copper version: http://www.humblehomemadehifi.com/Cap.html

 

As a result of this, the tinned copper version became the most seeking of the CAST range caps. And that is probably what drove the cost down on the other models.

Are any of these CAST range caps used in a DC4?

Hi Nenon 

You are probably the only person here who has heard these capacitors, have you done comparisons tests with and without Duelund caps? Do they make such a difference to justify those insane prices? 
Have you tried  the Duelund JDM bypass capacitors they are a bit more reasonable priced, in speaker filters or power supplies? In my speaker filters I used the Audyn TRI-Reference Caps but a little help from a few Duelunds could not hurt.

Is the Extreme using individual LPS rails? or is it similar to using a 800w HDPlex HIFI-DC-ATX card?


For what I can see there is one transformer with one output AC rail. That ac rail gets rectified in the second picture of @seeteeyou’s post, with a buffer capacitor and parallel bypass capacitor. Than a two wire negative goes to the capacitor bank and a two wire positive goes via the Lundahl choke and to the capacitor bank. From there it is unknown but underneath the capacitor bank are probably several linear or switch mode regulators for all the different voltages.

Boy Would I like a peek underneath that bank.

My mother board has suddenly gone down, ASRock Intel Z390 Phantom Gaming ITX/ac, anyone else had this issue?

The PH power supply and Hdplex ATX are working ok.

 

Sorry to hear that. I usually try to connect a regular PC ATX power supply with its stock cables when something goes wrong. And I also connect a CPU fan to see of it would start spinning.

It's a good way to rule out a dead motherboard vs. something else.

FYI - here's the official statement in 2019

Due to significant investments from our major distributors - a selection of the most popular CAST Silver 630v capacitors can now be offered at much more attainable price leves. 

 

And then here's the verdict

In contest are
- pure silver cast 1uf
- tinned copper cast 1uf
- copper cast 1uf

I would rate; - Pure Copper cast 9 out of 10 - Tinned Copper cast 9.5 out of 10.
...For the top end separation.

 

And the best affordable capacitor out there at the moment. ...So what is 10!!!? ...someone has asked me that question before. ;-),
I honestly don't know but at the moment I would say the Silver cast is 10 or even more...,

Duelund Pure Silver Cast capacitors. ...It's actually unbelievable what this silver cap does to the music!

 

It's like sitting in front of a massive wall of multilayered sound that comes from very deep black and quiet background and riches somewhere behind your head, sound of cymbals or piano has that beautiful glow around it and top-end notes sound so 3d as there are some ghosts around my head whispering to my ears,

 

it makes me listen to well-known by me tracks over and over again! wow!

 

I know it sounds crazy but the music becomes so tangible, involving and hallucinogenic that I have become a silver cast addict!. You get massive soundstage, deep and wide! super quiet background, big and well shaped bass and best top-end ever, never bright or annoying, ... I actually worried about that, thinking silver is known to be quite bright! But not in this case, Duelund silver sounds big and well balanced and takes you right into the show!

 

It's a real step up from an amazing copper family as the bigger price would suggest.

 

Unfortunately, they are not cheap, but you definitely get what you paid for.

 

I rate it 10 out of 10!

 

So far the reference! and best audio capacitor that I know of.

@RickyV is correct. The DC4 uses Audio Note caps and Z-foil resistors


Ah I didn’t know about the z-foil but was wondering if that would beneficial.

And I guess that there now 3 LT1084 used?

Thanks Nenon - will try that.

No. He has done something different that lowers the noise up to 1000 times for lower current draw. Exactly how much lower it depends on the current draw.

Anyone tried a MSI motherboard? thought I might try this as an experiment -MSI MPG Z390 Gaming Edge AC fr a server build.

 

I have not tried one but my current thinking on motherboards is more about the BIOS and what control it gives over various CPU and power settings.  

 

In addition, I found that the BIOS for the Intel ASUS motherboards were more flexible than the BIOS for the AMD motherboards.

I used to use MSI Z97I Gaming AC ITX - a little old now, but sounded very good to me.
