Low noise power supplies, 5v, 9v & 12v.

Recommended Posts

Just thought I'd be the first to ask a standard newbie question but what exactly is the purpose of these low-noise power supplies and what do they go with?

 

I have and have had a number of Clays supplies that I use/used for various things.  Mostly its to replace switching mode supplies.  You stick such a supply on a scope, and I have done this at Clays shop where he has the proper test gear, and its full of high frequency hash.  That gets down inside equipment and radiates about causing problems.

 

1.  I used it on a Chord Cute DAC - it lifts it to another level.  People have posted its then as good their more expensive DAC's but at a much cheaper cost.  I haven't done that comparison but can confirm its a definite step up.

 

2  Used on my Off-Ramp.  The switching mode power supply supplied produces horrid hash (it was the one I tested at Clays) - and the maker Steve Nugent recognises a linear supply is much better, and will supply his dynamo supply for $769US.  Clays supply is much cheaper than the base price of $769 plus you don't have our bad exchange rate, importing issues and shipping which makes it even more expensive.  I got him to make me one - it was significantly better with it for a much cheaper price.

 

3.  The supply for a NUC computer as a music server.  Clay makes a full on music server but a simple NUC with a good supply is nearly as good - at a much cheaper price.  Its what I use as a server when I used a computer.  I am moving to my Oppo 105 with Tidal, but having heard the difference between the NUC and a full on server simply couldn't justify the extra cost.

 

Thanks

Bill

Ahhh, I see. Thank you Jventer and bhobba!

 

I might be interested in getting one, depending on what DACs it would be compatible with.

Well you know I'm interested Clay! :)

for the less technically minded of us here ie. me, is there a way to work out what voltage model i would need for my dac

Hi Murray,

are you talking about the LM502ca? That cannot be run from a seperate power supply.

Wow, nice looking DAC.

Very interested. [How, Clay,do you think the 12V will work vs. Choke-filtered PSU that seem to be well-regarded for music PC?]

Hi Clay,

Thanks for the reply, yes I was talking about that dac, well that was a short lived upgrade path :-)

Hi zydeco,

the choke design that Chanh showed us is very nice & will probably sound better than even the best regulated designs. It will cost considerable more though. Hammond chokes from the US plus a Hashimoto transformer from Japan & Mundorf capacitors from Germany, brilliant combination. A bit like Grange I suppose, it you want the best but it's going to cost big time. My power supply design is far more down to earth but is well engineered with good quality components & a big step up from the Chinese EBay stuff. I have found some very nice regulators from Japan & after a week of R&D & some new techniques I'm very happy with the results. They will stack up well against the imported opposition, match performance & come with a local two year warranty.

The Hammond chokes are just cheapy run-of-the-mill production line transformers.  You could get better ones (that cost more of course) in Oz.  I am not familiar with the Hashimotos, but I reckon you could get comparable quality in this country as well.  As for caps, I would almost bet that a larger electrolytic would sound better in this application than a smaller film or paper cap like the Mundorfs.  But still, no easy electrical approval which makes things difficult if you are selling these supplies Clay.  Parts cost alone would be about $400 but you would be doing it with mostly Australian parts and will benefit by not having to be too concerned about the crappy dollar conversion at the moment.

 

By the way Clay, I like your initiative here with these supplies.  I think there is a good market for them. :thumb:
