Lumin D2 - Late the Table


I'm a hard core old school guy just coming around to digital and am in need of some advice.  I'd like to get into streaming and am looking at the Lumin D2.  As the unit stands you must have a hard wired connection to the internet for it to work.  I've read that there are work arounds to enable the D2 to connect to a WiFi network.  Is this true, and if so how is it done?  I have no stand alone DAC so I would be connecting the D2 to my ARC LS 27 preamp.  Aside from my stand alone CD player (Ayre C5MPxe), this will be my first venture into digital.  From a plug and play perspective the BlueSound 2i maybe a better fit but given the rest of my system (ARC 150 monos feeding Wilson WP 6) I'd like to start higher up the fidelity ladder.

wifi extender question has been answered - it works fine to provide an ethernet jack to gear that must have it

re the lumin d2 vs bluesound node 2i... if you definitely don’t want more boxes (e.g., an outboard DAC to use with the node 2i), i would go lumin... it will sound better than the node 2i using its internal dac, and sound roughly as good as your ayre cdp

your system seems good enough you will definitely hear the difference between the d2 and 2i using their analog outputs into your ARC linestage

You can use a cheap extender but why cheap out on your network?
 A mesh works much better with powerline.
I've done both.
I have owned the D-2, A-1 And X-1.  I can tell you there is a big difference in sound quality from the D-2 and A-1.  Then there is a night and day difference between the A-1 and the X-1.  So, if you have not purchased the D-2 yet, you may want to find a used A-1 or S-1.
@cmcdaniel5 definitely as willgolf says, if you can afford it then one of the higher-tier Lumin streaming DACs will get you farther up the fidelity ladder you're looking to climb.
