Linear Power Supply for a DAC

I have bought several PSUs from Paul. Never an issue. One just has to wait. It is what it is and all know that in advance.

No one has ever lost money with him, as he is honest, but by necessity, just slow.

You want the best, so just wait.

Alternatively, get a HD Plex!

LPS for digital has different requirements than for analog preamp etc..

The digital LPS should be very fast reacting to provide the current transients for digital.  I recommend the Sbooster supplies.

Analog supply should be quiet, can be slower responding but input noise rejection is important.  Paul Hynes supplies do the best job of this.

Paul has had some factory issues over time, but he has his own shop again.

Power supply specs are: 12v, 1A, 2.1mm connector. The DAC has a grounding post if needed.

The Paul Hynes SR4 is a production model; see his recent email comments to me:
" The new SR4 is intended as a stock item with 10 units per month introduced to stock. As long as the SR4 is in stock it should normally be shipped out within 3 working days from order placement. If the SR4 is out of stock during the month of your enquiry, I can place your name on the waiting list for the next available SR4 unit and notify you when it is available. The next production batch of SR4 with available units is scheduled for manufacture during the last week in February with shipment occurring during the following week."

 If you are looking for one of his other models, such as SR5 or SR7, then expect a wait. I emailed him at:   paul@paulhynesdesign.com and got a very prompt and detailed response.

I have been looking for a good 15V / 2A linear power supply for my tube DAC (4 - EC86's) and feel like it would be hard to go wrong with a Paul Hynes unit. I am currently fascinated by another British manufacturer, Custom Hifi Cables Ltd, their dc2 or dc3 models
( http://www.custom-hifi-cables.co.uk/home/power-supplies/-dc2-dc-power-supply ). Mojo Audio has factory reconditioned Joule v5.0 models at good prices & warranty but I have yet to hear from anyone who has had one ( https://www.mojo-audio.com/specials/ , there is also one on Audiogon for less). I will go back and find some other brands that are intended for audio but quite reasonably priced.

What power supply specification or other property could one use to tell if one supply is faster than another. I am also looking for a very good linear power supply for my Acoustic Plan Digimaster DAC which uses 4 - EC86 tubes and has a 15V ? 2A DC input.

Do power supplies have different "sound signatures" (if that's the right term). Acoustic Plan makes an optional linear power supply, the Powermaster, that will run two of their components but it costs $2000.   

Hi guys

if you remember i told you paul is not trusted and he not refund my money after 6 month.

now Paul have sent me an email and he told me he will refund my money this week.

Good news to me and other who would like to order Paul hynes PSU.

i should say Paul is trusted and if you pay him he will refund your money .

There is nothing in the specs on most power supplies that will tell you this unfortunately. You have to try them out and compare them.

They will cause different sound signatures in different components. Slow reacting supplies will reduce dynamics (slam factor). Supplies that do not have tight regulation will cause smearing and loss of focus. Supplies that do not have good AC line noise rejection will cause noise in the music.

I have gotten positive feedback on the Sbooster supplies.  I believe they are fast reacting.  They are not earth-grounded, but this can be added by using the right cabling.

Hello, hello,

I wanted to see if anyone could suggest where to list or sell the Accubasston Linear Power Supply that's mentioned in this thread. I have considerable experience selling things on the internet and I'm pretty sure this won't sell on locally or on eBay or Audiogon. Any suggestions are appreciated. Thanks, guys.

or can try this iFi iPower Elite 12V, I have a huge upgrade of SQ on my dac.

I have a Farad power supply being delivered from the Netherlands tomorrow for my Chord Dave DAC. Thier prices include shipping but they aren't cheap.  

Dave uses 3 voltages so I had to buy 3 power supplies plus a custom harness than Farad makes.

They have what you need for Chord Qutest on the shelf.

I haven't heard it yet but if you give me a couple of days I'll post my impressions.

Good information here!

I recently added a Sean Jacobs DC4 ARC6 LPS to my (M Scaler) DAVE. It is a remarkable upgrade.  Expensive of course, but brings DAVE to a level so far beyond the stock power supply it’s hard to believe.  

I have a Swagman Labs SE LPS that's worked well for me. I'd like to upgrade the stock DC cable from the power supply to the 2.5mm barrel connector.

First question; what is this cable called? It has a lockable circular plug.

And lastly, any recommendations (under $100) ?

Ok, now I know what I'm looking for. Any recommendations for a DC cable for linear power supply with lockable circular socket? Twisted conductors rather than the stock cable. Thanks.

I only found Canare in the archives.
