Final Conclusions

 

The Farad Super 3, in addition to being an excellent PSU as I found in my previous report, has the added advantage of a continuous current capacity of 3A. This puts it in a unique position compared to lower powered supplies like the LPS-1.2 and the SR-4. The field of high-quality PSUs with current capacity over 2A is quite limited, and the Farad is a welcome addition. I can see it being a great fit for DACs, and other current-hungry devices like NUCs.

 

For my use case of powering a Chord Hugo TT2, the Farad Super 3 was not only up to the task, its SQ while doing so was excellent. 

 

I next look forward to Mattijs' higher current Farad supply, now in active development.

 

 

 

Great write up Rajiv!  I'm impressed and surprised that you were able to hear such a significant difference with the TT2 (I would have guessed the internal supercaps would dominate).  Intriguing, and a reminder that guesses and assumptions are just guesses and assumptions.

 

By chance, did you compare SR4 vs SR7 vs Farad Super 3 @15V on the Hugo mScaler? No supercaps in that power chain to make assumptions about ;)

Thanks, and yes indeed!

No I didn't.  There are some logistical challenges with doing this, so no promises. I'll see what I can do.

As promised, here is my followup. This time, I'll describe the 15V unit

 

Thanks so much for posting the follow up as promised, Rajiv.  As a TT2 owner, this was of course tremendously helpful.

@austinpop question about the Super3.  Does it require a charging supply like the LPS-1?  Or does it have an IEC on the back for connection to AC?

Thanks for that write-up, Rajiv.  I know the TT2 can benefit from a better than stock power supply because I’m currently using it with the Poweradd Pilot Pro 2 and hearing a slightly cleaner sound, albeit at 12V.  But I would like better than that if I can get it, and at reasonable cost.

 

Just looking back at your wonderful “My quest for a new DAC...” report I see that you said of the DR SR7 On the TT2, the effect of the SR-7 was modest at best”, so I’m just wondering how big the jumps were from stock to 12V Super3 to 15V Super3 to SR7.  I expect now with greater familiarity of the TT2, and perhaps with further refinements to your system, are you finding it easier to hear these differences?

 

I’ve surrendered my SR7 build (felt like I wasn’t going to see it for between 2-4 years), so the Farad Super3 and Sean Jacobs DC3 seem like my best bets for an upgrade supply to drive the TT2. The Farad with silver dc cable would be about half the price of a single rail DC3 with Mundorf caps, upgraded silver wiring and silver dc cable.  What to do, what to do...

Correct. It has an IEC inlet for an AC power cable.

 

Awesome - wish Uptone would have done the same with their LPS-1 series.  Thanks for the prompt reply.

At long last! Looks very interesting. Folks who are going to RMAF - I'm not, sadly - please report back.

 

The obvious comparo of "massive" interest would be - an identical upstream chain followed by:

  • Phoenix -> DAC, vs.
  • tX-USBultra SE (SR-7 DR, Ref-10 10MHz reference clock) -> DAC.

Also interesting would be if the Phoenix further improves the output of a Statement.

Finally!  At 3x the price of tX-USBultra and 10x the price of an ISO REGEN, this better be mind blowing.

Add to the price of one more quality power cord and another audiophile USB cable 😶

No.  A far more interesting comparison would be with  tX-USBultra, SR-4, REF10 ->DAC.

(More interesting for me at least, because that’s what I happen to have lurking in my rack)😁

 

Anyway, whatever comparisons actually transpire, I will be as interested as anyone, here’s hoping someone manages to try it.

Let's put that price in context. If you add up the approx price of:

  • a tX-USBultra SE with master clock input:    $1500
  • one rail of an SR-7 DR:                                      $1300
  • one 10MHz clock tap from Ref-10:                $1300 (assuming you use the Ref-10 with 3 devices)

You're still at over $4000. If the Phoenix can match the SQ performance of the above combination at $3149, they may have a winner on their hands. We won't know until it's been tested.

 

Match the quality of the SR7, arguably the most important component? Doubtful. Then match the quality of a REF10?

You are probably missing a very important point - a quality standalone power supply (or even the standalone external clock) is always reusable and in computer audio there will always be a need for it. If the Phoenix didn’t float the bloat, you take a big hit selling it. Additionally, most of the folks don’t have the luxury of PH SR7, nor do they even use an external clock such as Ref10 - so it’s probably unfair to generalize the cost at the gross level. As I see it, the Phoenix is quiet a bit expensive for just being a re-clocker but time will tell, off coarse.

I think the reason austinpop included those components is because that's precisely what's in the Innuos offering.  So it isn't really "just a re-clocker"

There might be yet another important point that we're missing, Innuos made that decision to put everything inside the same box in order to minimize the degradation of clock cables. In Roy's experiences, even average clocks inside the same chassis that were powered by average PSU could work pretty much as good as something else that's much more expensive

For the PSU side, he also talked about how internal hardwiring could trump external DC connectors

Currently we do have plenty of both RCA jacks and plugs with pure copper contacts but they might not be exactly the "right" choices in terms of DC power. OTOH, Furutech made some jacks while Silversonic made some plugs as follows

Speaking of connectors with pure copper contacts, could @austinpop please kindly ask the member who made that DC cable (with Oyaide FTVS-910) about this company in Japan?

They seemed to be able to manufacture some (pure copper) male connectors for headphones but the female ones are only good for adapters, therefore not meant for the jacks that are mounted on a chassis. However, they also listed something about custom orders on their site and it would be great to find out what the minimum order is. Thanks.

Perhaps offtopic, but just a brief comment on this:

The Jaeger connectors Paul Hynes uses in his upgraded SR7 are really good! I use them too... with the Mundorf SGW115 wire and JSSG360 in my LPS. 

https://www.sealconusa.com/images/connectors/pdf/standard-rapid-series.pdf

 

Look at the 50A / < 0,0007 Ohms "533 760 006" for example.

But don't forget that there is about 20x more resistance in 2 feet of 18AWG wire. B|

 

Of course! More like 8x more resistance for the 15 AWG Silver but still a valid point. 

But also, a regular 2.1 mm DC barrel jack plug has 29x more resistance (reference: Switchcraft DC connector specs).
