Just like many of you, I have also been looking at an affordable linear power supply that would meet my needs. I stumbled upon this newly available PSU from HDPLEX: HDPLEX Fanless Linear Power Supply for PC Audio and CE device

It can be used to power two devices simultaneously, my main audio player (19V) and NAS (12V), and is affordable as well. Because I live in Europe, I saw that they also send from Germany, which saves me on import duty and taxes. Combined with a favorable USD to EUR rate, I decided to order one. This week the PSU arrived and I put it to the test. I have listened to it for a couple of hours now, but the improvements where spotted easily. Because I already use a separate power supply on my USB-S/PDIF converter, I did not expect the effects to be big, but it turned out to be a very welcome addition to my setup. As noticed in other threads, I found that the linear PSU improved the sound on imaging, transients, detail and bass. Especially on live recordings, there is a huge improvement in detail and realism. Overall I am very pleased. If you live in Europe like me, this PSU might be a good option to consider.
