Power Supply recommendation


I have a defective wall wart on one of my stereo network devices. Can anyone recommend some brands/sources of good quality power supplies. I need a 5V .5 amp output. Not looking for anything in the thousands but have no problem spending a few hundred or so for something good. Also Chinese made is fine if its good quality.

If you don’t mind Chi-Fi, the LHY LPS should be on your list of considerations. I have LPS25VA and LPS15VA. Both are dead quiet and good performers.  The LPS25VA has two outputs, suitable for powering two low-current-demand sources. The cost is around $190.

Cheap one trick pony,....Topping P50, $130

If you are looking for something better, I use a few of these KECES units for $550

Since they have dual independent outputs and can accommodate a variety of voltages (5V, 9V, 12V, etc), it’s a more flexible option as your needs change.

@deep_333  No offense, but I tried the P50 a while ago. The power supply lacks headroom and generates a lot of heat.  My Lhy lps, 15 or 25 watts, gen. literally no heat.

I really like Pine Tree Audio. If you call, you speak to the designer who will probably also build your unit. They make and sell linear power supplies, as well as many interconnects, speaker cables and useful devices.

First, thank you for your brilliant post on one of my previous discussions. Unfortunately, it was removed by the moderator! Wish your post would have stood the test of time, but this moderator is rather careless. You were right on the mark.

Cal Test is a top-notch brand. 

Used their products in the past for mission critical electronics. Very reliable and great specs. They are typically known as "test grade" and calibrated to provide better ripple performance for longstanding reliability. Shouldn’t negatively impact anything... might even improve it! smiley if nothing else, look into this brand and others like it that are more serious than generic brands you may find on amazon... had a lot of those wall worts go bad in the field (in IT) due to poor quality control. No such problems with this brand. 

Good luck! Have a great night.

+1 on Teddy Pardo

+1 on Pine Tree Audio. Jesse can bling them out if you want. I added a VU meter for a retro look.

Call The Cable Company and have them send you some demos. Why take a chance and guess?

@052rc I'm not looking for a $2K-$3K power supply for a network device. I thought The Cable company only lent out cables?

@willywonka How many pieces do you need to power? Small Green Computer sells the HD Plex that has 4 outlets and each can be adjusted to correct voltage. It has gobs of power. I have one.
