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.

Just keep your digital gear & SMPS type psus and walwarts AWAY from your analog gear. That is all you need to do. They may affect your analog gear but they will have NO effect on your digital stuff
This is actually inaccurate.  The power supply on digital equipment, including digital transports such as streamers or disc players, will defintiely impact the sound quality.  If you cannot hear a difference on this it means your listening skills and/or hearing are not as sensitive as others or your audio system does not have enough resolution to reveal these differences.

I've been reading this thread.  I think the OP has a good point on this product for an alternative to the really cheap small 3" x 3" wal-warts that come with a lot of our audio equipment.  Of course, this will not be as good as a nice linear power supply (which he has said), but it should give a good improvement over this small wal-warts.  For $50 you can get a nice improvement, but for $250-800 you can get the top end linear power supply.  It all depends on how much you want to spend and how important it is to you.

The noisy PS is 12-18 vdc, that I'm using, it should to work. ay?

This power supply is a single voltage output.  You can choose either a 12V model or a 24V model.  If your equipment has a dual voltage requirement or a special type of power supply (such as a laptop), this power supply will not work.

I'll check it out. It's for a cable router, from the cable company. All of them are noisy. They have to be on a different circuit. No noise problem NOW, but it took a GL device and a different circuit, to do it.. They use to pull more watts than a class d working hard.. Quite the piles of dung..
BUT, I like the Music Channels, the wife like "Below Decks",

I haven't watched TV in 3 years. 2-3 hours at the kids maybe..in 3 years..

3rd or 4th one. This was the cable company's fix... I moved it to a separate circuit.

For reasons stated earlier in the thread, I don't buy into linear PSU for a router/networking device.  I do for anything outputting audible analog signals.  Being lazy at one point I had a power strip with all SMPS for various things plugged into an outlet shared with a Panamax filtering strip for my amp, DAC and preamp, and one day realized that things didn't sound as good as I thought it could.  I had received my shipment of equipment from storage after having recently moved and was in a rush to hear my gear again.  It took me a few moments to realize what I had done and when I did I moved that whole strip to another outlet a few yards away which don't run near each other at any point before the breaker box.  The sound improved quite a bit.  A smaller improvement was had by moving the power brick for my tiny PC to a filtered outlet on the Panamax.  I think that last one may have had something to do with USB and it transmitting power on the cable between the PC and the DAC. I think the lighting strip is a good solution if noise is an issue even after putting the devices on a separate outlet. Minimizing the noise on the AC circuit closest to the amplification is pretty important. 

@oldhvymec, I keep my DVR turned off.  It's a WAF thang that it's even in the rack.  Damn HDD can be heard when I have the house on quiet mode (air filters, and cat water bowls turned off).  I hate that you can't truly power off a cable DVR unit. I put a remote outlet on that thing so it turns on and off for the times that my wife might want to actually watch tv and can use voice command to turn it on otherwise.
