Just a caveat - are you sure a single Farad 3 supply has enough power for your needs? It's a great PSU, but it's limited to 3A, as you know.

 

The whole point of the single server that Roy mentioned - see this post and this one - is to power it with generously overprovisioned PSUs, which we think contribute to the outstanding dynamics. Even with his current server, which I believe he mentioned consumes under 50W steady state, he is powering it with 2 rails from his SR-7:

  • a 19V/5A rail to an HDPlex DC-ATX adapter, which then feeds the ATX input (12v, 5v, 3.3v) of the motherboard.
  • a separate 12V/5A rail to the EPS input of the motherboard, to power the CPU separately.

That's way more than a single Farad Super 3 can supply - nor is it designed to.

I was told that the HDPlex 400 DC-ATX needs 10 A to run properly

Where did you hear/read that? HDPlex recommends their own 200w LPS with it for audio applications and I can find nothing on their site that mentions needing 10A. The 12v and 19v outputs of the 200w unit are rated at 10A but that is their max, not a recommendation.

 

Thanks.

The builder of my HDplex told me. Though I suppose  it may still work at 5A if CPU is powered separately. I have a 8-core CPU, not sure if that can be a factor too. Got to check with Larry.

Also didn’t someone here tested this out and found that it requires about 6-7 A ? Or was it 6-7V. I can’t remember, sorry for confusing people!

If you buy a Farad3 for your NUC, I recommend getting the 19v version.

I've bought a Farad 12V for my NUC ( 7i5dkne). I run euphony From USB or AL in RAMroot with no disks attached. 

I've  chosen the 12V so I could be able to use it to power a CPU in a future build. I also think the 12V version is more widely used in switches and converters etc so it might be more future proof. Just my thinking. 

Can you tell me why you'd recommend the 19V instead of the 12V? Better dynamics maybe?

The dynamics are certainly better.  It's been awhile since I made the switch from 12v to 19v, but I also seem to recall the bass was more palpable and the image was more three dimensional.

The subject of today’s scrutiny was not actually another music server debut however. As a step up for the popular Zenith Mk3 server ($2,600 USD), Innous was announcing a bit of signal polish in the form of a USB reclocker called the Phoenix ($3,150 USD). Intended to push sound quality levels even further, the inclusion of the Phoenix (B) did in fact add some crisp focus and smoother, organic delivery to the Zenith (A) during the initial A/B comparisons in the room.

 

Glancing up at the rack, it was beyond the control of my curiosity to not ask for yet another option with the resting reference Statement server (C) that I had been very impressed with at other showings. While perhaps not the direction the demonstration was intended for, the resulting equation did make it clear that A+B did not equal C. Comforting news for those have already purchased the flagship at $13,000 USD. While resolution delivery improved along the upward path, in this YG Acoustics-fronted demo the staging appeared to deepen at A+B, then widen at C for a satisfying sonic illusion as things moved forward.

LOL I thought that was strange too.  At least he didn't say 37 going on 38!  He is an excellent dealer, I've bought things from him.  Really responsive communications.

 

Nice! Well there's a lot to be said for that in this day and age.

My Audio Clock Journey

 

Hi CTU

I am not so slow this time. I got my Cybershaft OP20 Limited 2(same as Ultimate but with 3 outputs instead of 1 output ) a month ago and has been burning it continuously for a month now.

 

FYI - here's a comparison among Cybershaft OP14 / Titans Horae / Cybershaft OP20

I tried a 7 A brick with the HDPlex DC-ATX and could not boot a modest mb with 25w CPU with the HDD powered separately.  A10A Teradak LPS booted this computer successfully. Just another data point in case someone encounters problems.

Yah weird why he mentioned his age. But I bet one can build a similar unit at half the cost, though may not look as sleek. 

I would be curious as to how you would quantify that assumption?

£2250 a pop for Phoenix so let's crunch some numbers

 

https://www.audiofest.net/innuos-launches-the-new-phoenixusb-reclocker-at-rmaf-

Quote

All 3 independent voltages to the chip originate from an independent linear power supply with further regulation provided by 3 sets of LT3045 regulators.

 

Two independent Statement-level linear power supplies, one dedicated to the OCXO clock and the other used for powering the USB chip/5V USB line.

 

So we're talking about two separate transformers inside the same chassis, correct? And then we'll have to add some Mundorf caps as well

 

http://www.custom-hifi-cables.co.uk/home/power-supplies/dc3-power-supply

£700.00

 

Upgrade to Mundorf capacitor arrays:
add £200

 

Extra separately-regulated outputs:
add £200

 

Hard to get hardwired power cables / clock cables anywhere else.

At current exchange rates, that's about $2775 in USD.  The USA price is $3150.  I guess that's a nice uplift for the US distributor.

At least that kinda difference seemed to be relatively "moderate" when compared to stuff like this

Esoteric introduced the new P1X transport ($50,000) and D1X Monoblock DACs ($50,000 pr.) in an all-Esoteric system.

Quote

Grandioso P1X - Suggested retail price 3,500,000 yen ($31, 670)

 

Grandioso D1X - Suggested retail price 3,500,000 yen / pair ($31, 670)

 

And then take a look at their royal treatment if something were sent all the way back to Japan

Not exactly sure about the difference between list / street, though.

Does anyone rate any of the nucs with optical out? Or is it a case, if you go NUC then you go usb?

 

This one was HDMI to Toslink

Another one was Mini Toslink to Toslink

However, both of them were owners of Chord DAVE (with M Scaler added) and supposedly they're known as jitter-agnostic DACs to begin with. Maybe take a quick look as follows?

https://www.diyaudio.com/forums/digital-source/37122-optical-cable-jitter-measurements.html

 

BTW, there will be something called "ElectroTos" available soon and IMHO that's quite interesting

https://www.forum-hifi.fr/thread-12116-post-275663.html#pid275663

Quote

"ElectroTos cleans up the S/PDIF stream (by avoiding reflections and jitter induced by Toslink interlink). When a cleaner S/PDIF signal is sent to a DAC it is likely that the clock recovery inside that DAC is better and so it usually performs better regardless of the overall quality of that DAC."

Is the price without VAT?

Hmmm, seems like there might still be a few things missing (i.e. USB reclocker, case, etc) plus the standard DC3 is not built to Statement specs. Of course you will have to build and test it yourself, so please don‘t forget labor ...

Good question.  If the UK price includes VAT, then the US price (which never includes sales tax) looks even worse.
