If you follow my ramblings here (and elsewhere), you may have noticed this device pop up in pictures on several recent posts of mine. It's just there in the background, doing its thing without calling much attention to itself. And yet, in many ways, it's the backbone of my reference system. The item in question is a new product from a name veteran HeadFiers will probably remember - Keces Audio. The company had some popular DACs roughly 10 years ago, known for their high value and musical sound. The little DA-151 was among the very first USB-only DACs I ever encountered. I don't believe the company ever really went away, but they seemed to focus away from the North American market for some time there. That changes now with the launch of Keces Audio USA. The focus seems to be power products - I don't know if Keces has a larger portfolio for other markets, but for now North America gets a trio of isolation transformers plus a pair of linear power supplies. Like the early Keces gear, these models all seem to offer quite a bit of value per dollar. The one I'm using is the Keces P8 Linear Power Supply. Some specs from the site: Toroidal transformer: a high-mass, low-profile, low magnetic field design No Humming or Buzz noise for 50Hz and Peak load, 100% Silent Low ripple noise and void of high frequency noise 4A+4A or 8A continuous power Each output has two selectable voltages *All version included a USB output Features 1. High Quality Toroidal Transformer provide pure power. 2. Separate ground for each output rail. 3. Ultra low ripple noise. 4. No humming or buzz noise for 50Hz and peak load, 100% silent. 5. OLED display currently output voltage and currently output ampere. 6. USB Type A 5V output 7. Dual output with USB output provide 4A for each with 1A USB output. 8. Single output with USB output provide 8A with 1A USB output. 9. Over Voltage Protection (OVP). 10. Over Current Protection (OCP). 11. Under Voltage Protection (UVP). 12.

DC Connector 2.1mm Barrel AC Input Voltage 115V 60Hz / 230V 50Hz (Switchable) Power Consumption 210 Watts (Full Load Output) Casing Aluminum Dimension (WxDxH) 300x220x66mm Weight 6kg As you can see, this is a flexible device that can be configured any number of ways. The most obvious would be dual outputs - one for a music server or streamer (Squeezebox Touch, sMS-200, microRendu), the other for a DDC or USB widget (Wyred Recovery, Uptone Regen, etc). The only limitation is the total output capability of 8A - far higher than the somewhat conceptually similar Wyred 4 Sound PS-1. That device handles a maximum of 4 devices but shares 4A total between them. The Keces P8 only does two devices... BUT! Don't forget the USB output that can provide up to 1A at 5 Volts, making this a three-device PSU if your gear needs happen to match up. The USB output can be tapped using dual-head USB cables, or get an adapter from Keces USA to work with low power equipment. Me? I got the single device version feeding a Zenion music server. But I've also got the USB output feeding a Matrix X-SPDIF 2 DDC, and the result is spectacularly clean, rich, and musical. Running the Zenion with stock power brick, powering the Matrix DDC direct via USB power, just isn't the same. Still good, sure, but I the P8 brings very tangible improvements. I particularly enjoy the inky black background it produces, which is impressive considering I already run high-end power conditioning for the entire rig. Improvement is even more dramatic when I run straight from wall power. I really enjoy the OLED display which shows the draw of connected gear. It looks like my system generally needs somewhere between 2A-3A when playing a single stream in Roon endpoint mode. But I see the draw ramp up when I do multi-room audio and DSD upsampling. This particular system still doesn't push the limits of the P8 but I bet I could throw together something that would if I really wanted to. That's where the OLED would really come in handy. I'll have more thoughts as time allows. Just wanted to get this out there because I keep showing pics of this thing without ever really explaining what it is and why I like it so much. Did I mention it goes for a very reasonable $599 regardless of configuration? Single device that needs 12V, or dual outputs at 7V and 15V? Doesn't matter. That said, you'll have to inquire about custom cables for your particular devices, as I don't know what the price spread on those might be.
