Excellent Power Supply Solution

In case you haven’t noticed, it’s very hard to find a good, affordable DC power supply from a U.S. dealer. I wanted a 12 volt 3.5 amp model for a Netgear router.  The quality linear power supplies are considerably more expensive than the router. But, then I stumbled upon an interesting product from Waveform Lighting. They offer a $49 DC power supply for strip lighting purposes. The 12 volt model can handle up to 10 amps and 100 watts. I do not know the technical details on how it works, but the description states “very low ripple and noise.” It also has overload voltage protection. The DC cable is 16 AWG wire.  A nice feature is that you can attach an audio grade power cable with a C7 connector. I used a Shunyata Venom cord. 

The unit did add a noticeable increase in sound quality. A little more clarity, more lifelike vocals and less harshness  in the upper treble. If you have a 12 volt modem, router or switch, give the Waveform Lighting DC power supply a listen.

Why do you keep starting off post like this? REALLY, are you trying piss folks off?

You just can’t stop, can you?

Oh the wonderful power of suggestion even self suggestion.

Ok audio2design will the dog gone thing work? Geez, you make my head hurt.. Is it a good deal or a bad deal? Have you looked to make sure?

I have a noisy power supply on my cable box, what’s the fix? I have to use a GL eliminator, ONLY friggin’ one out of everything in my house that uses those things. It makes noise through my speakers.
I understand there is a voltage difference, the cable company admits it, this is what they use to fix it...

Can this help, do you know it won’t help? I keep reading why stuff won’t don’t, couldn’t, and not possibly work, ALL the time, but you haven’t tried the stuff or read the information. Just Blanket it won’t work, and sighting WRONG ripple? Low ripple, there should be a number published what it can do, RIGHT? What’s the answer, NOT this is the wrong question?

Easy to say no... WHY on the other hand.. whole new world... It’s called being a mechanic... YUP.. I fix it, there has to be a fix for a bad or noisy PS.

How about try this (what ever it may be), it may work better, for your apps.
One of the 6 Eeyore’s. Oh No, I had to say no again, oh my.. LOL

Quit holding out on the goods, if you got an answer offer it up. If you don't, go find one... Simple...

oldhvy, stick to mechanics :-)

It’s a laptop power supply. Here, you can buy directly from the supplier:

Model YHY-1201000 just like on the Waveform Lighting site. It is a two stage power supply so it has low flicker for lighting purposes. And yes, the pictures match exactly what is on Waveform Lighting site.  It even says only use for IT equipment purposes (not lighting)

@cakyol,

first, I object to your stentorian, arrogant tone. You are dealing with people enthusiastic about their hobby and by and large able to hear very well, and not a bunch of miscreants

Second, the issue with PS generated noise ISN‘T about missing bits in digital transmission but about ground level noise travelling along the data path and deleteriously affecting the digital to analogue conversion, i.e. it is an analogue rather than digital problem which on first sight isn‘t covered by your digital expertise, however profound that may or may not be.

Finally I suggest you might start listening yourself rather than argue from first principles
