"I was nothing but impressed with the Lumin Network Player"

"Lumin is the network player by which all others should be judged. A definite leader on the Computer Audiophile Suggested Hardware List."

"What You’ll Need: To begin youll need a home network with Wi-Fi (pretty common today) and an iPad (Gen 2 or later, Retina displays welcome) to run the Lumin App for Apple computers. (Kinsky is suggested for non-Apple OS . And other tablets will work but with limited functionality. Lumin is currently developing Android versions.) To get up and running the typical configuration connects the Lumin and the NAS to a router using Ethernet cables (I use a Netgear GS 605 and AudioQuest Cinnamon), and the Lumin to your preamp or integrated amplifier inputs. The Lumin power supply then connects to the Lumin. Once everything is switched on simply confirm that the UPnP media server (MinimServer) is operating on the NAS drive. (Lumin recommends Synology drives for their ease of installation, legible set-up instructions, and compatibility with MinimServer, a free download. No arguments here. I use Synologys 1TB DiskStation, and it works like a charm.) The Lumin App will then automatically detect the media server and the Lumin player, and the music selection on the NAS drive will be displayed in the main Lumin App window. Once the Lumin A-1 is up and running, the only role the laptop plays is uploading music to the NAS. And even then it can be done wirelessly over the network."

"Network Challenged? No Worries! For those not especially interested in getting their hands dirty in the world of NAS drives and home networking, Lumin recently debuted the L-1, Lumins own UPnP server with internal storage capacity of 2TB. It’s roughly the size of the Lumin power supply and also sheathed in aluminum. The L-1 was developed to be the simplest way to store music for a Lumin DACdesigned to take the sweat and angst that the novice might encounter setting up a NAS drive. It meets UPnP standards and requires zero configuration. Simply plug it into your computer, drag and drop your music, just as you would from a simple USB thumb drive, and then connect it to your network. Used in conjunction with the Lumin app, it can also unlock additional browsing features. Like the player, it serves up everything from DSD 128 (5.6MHz) through high-res PCM to WAV, FLAC, Apple Lossless, and MP3."
