30W version.  Give the test data a good look  :thumb:

Yes it's very good. The ripple noise also goes up with load. With the load this DAC presents, The P-P ripple is under 1mV with this supply. And leakage current is only 50uA.

Found this ic while trolling for a diy chip amp project. attempting to mate this ic to a low noise switching power supply. 4 layer pcb. mono block layout. hopefully i will have this built up in the next couple weeks.

This PSU inside a black painted steel 1mm box -like my DC Blocker- with Schurter -with two fuses- inlet or Schaffner RF/EMI FN 9244B 1A filter (B = medical) maybe a good and cheap idea.

You can see here the HWB series was discontinued, and no substitutes to replace it:

Once current stock is burned up, that's it.

ugh... that suxs  :o

I guess I am going to use this for my NuTube Preamp.    its only 200ma but shunt regulated.

interesting link , I wonder if this German Company ships to US.

I'm sure he does. DHL.  I'm going to get some 24T V2's in for testing.

Hi Mike, is there a replacement for the now discontinued model,
http://daitronglobal.com/products/power/hfd30.html
Also, are there higher current supplies with as low a noise measurements?
Something in the 5 to 10amp range.I am interested in the lower impedance that a higher current models have.

No. All newer supplies are noisier. No dual output supplies anymore either. But they're still very good.

I decided on this case model:

http://www.hammondmfg.com/pdf/1455T2202.pdf




Comes in silver, black, red and blue. Also you can choose from plastic, thin aluminum with plastic bezel, and die cast aluminum end caps. I can probably have some nice end plates machined to offer folks who want to upgrade.

Very interested - do you have the complete specs, package list, pricing and how to order yet?
thanks

No not yet. It probably won’t be ready for a couple months. I’ve slowed down the amp orders to a maximum 20 a month starting at Lot 6. This way I’ll have time to work on this and other projects.

Is there a streamer available that you recommend?  I ask because if I go all in for a new DAC, I would likely use the computer server I have under my bed and then a local device to connect to the DAC in my living/listening room.

Well you can use one of Sonore's streamers. But won't be able to use my DSP engine. But you can use Roon or HQplayer to upsample to DSD 256 and it will work.

I pinged Daitron about the availability of the HFD30-15 power supply. Here was their response:

Unfortunately, Daitron has no more available stock on the HFD30-15.  We do have some HFD30-12 (12VDC) is that is an option.  I have 43 of that model still on the shelf.

Wow they had lots last time I talked to them. The ultra low noise supplies just aren't selling because the linear regulators are so good now. Even some switching regulators have under 100uV ripple now.

But sucks the new supplies are all single voltage. Same with Sanken.

Hi Guys,

I've been thinking about how many owners of my amplifiers will never be able to hear the full potential of them because of limitations with their source gear. At the same time I understand some folks have budgets. Since I already know how to build DAC's that will slaughter $6000 well reviewed, and very popular DAC's for under $500, why shouldn't I reward my clients with the opportunity to build such a DAC to replace their under $6000 DAC they currently have, and start enjoying better sound for very little money?

So I decided I'm going to work on a DIY kit that will accomplish just this. Only catch is this will only be available to current amp owners. This is my way of continuing to give gifts to the great folks who have supported me so far.

Stay tuned folks............. :)

Please, please reconsider in making your DAC widely available  :D I simply don't need another amp (I keep repeating to myself haha), but would love to try your DAC...

Thanks;

I'm thinking I just might give $300 off to amp buyers, rather than making people buy an amp. So the entry price for amp owners will be $500, but $800 for non amp owners. But if the DAC buyers decide to go with an amp later, I'll give $300 off on the amp.

To qualify for the $300 off, you can only buy 1 DAC for every amp you bought. And must be all the same contact info that bought the amp.

I might just need to build my own super hybrid supply. Needs to fit in the same size case as the DAC. This can be the Uber premium option.
