FIIO JadeAudio/FiiO PL50-Low Noise Regulated Linear Power Supply 12V/ or 15V Output for USB DAC HiFi Amplifier/Music Player M17

I'm not saying this will make a huge sonic benefit to your hifi but there are some significant changes to the way the sound is portrayed by adding this LPS.I've tested this powering both my headphone dac amp and my Temple Audio Bantam Gold class d amp.There is definitely more authority to the overall sound.I've also detected an improvement in the separation of instruments. Not so noticeable when music gets busy but if it's just a vocal, drum, bass and guitar it's so much easier to follow each instrument individually.The build on the outside is very, very good. With a nice clear display. At some stage I will take a look at the internal components to see their quality.I will definitely be buying another one. It really is that good.

I use it to power my RME Babyface Pro soundcard and it works perfectly. Sound is much cleaner, detailed, joyful than via a cleaned usb from the computer. I have added a shielded power cord to it and installed a hi-if tuning fuse in it.

You can hear the improvement in sound, especially in low tones and better dynamicsI use it with ADI-2 DAC, Fiio M17, Focal Clear MGI had iFi iPower Elite before, but I think this one is the best

Had this for nine months and today it just died on me! Not good at all. Would Fiio kindly suggest a solution. I am annoyed. Surely this lps should last longer than nine months!

Very happy with this power supply. It did seem to improve the SQ of the headphone amp I use and I think it's good value.

I haves used this with an RME ADI-2 DAC FS. Well, I was surprised . Not a snake oil solution as I feared it might be, but one where I could actually hear the difference at an 1/8 of the cost of the RME linear DC PS. It has made an already excellent DAC better.

Bought to use with a Fiio Q7. It is nicely made and finished, and completes my M11S and Edition XS rig.I am extremely pleased with overall performance.
