Digital Files and Wi-Fi

So, here's my current situation.  I'm a Luddite and use my MF Nu-Vista CD as my front end. I like that method just fine, particularly when I read about getting "CD quality" from digital files; to me, if one wants "CD quality," then just play a CD and be done with it. Unfortunately, that does not seem to be the prevailing wisdom, and it appears that digital files are the wave of the future. 

I started ripping my CDs to a computer with dbpoweramp. That's a bit of a project in and of itself.  I don't have an ethernet connection on the floor where my listening room is located and installing one will be difficult from a practical perspective. So, I likely will have to go wi-fi for adding something to my rig that can play digital files. Not really interested in streaming at this point, although many people tell me I will want that in the future. Initially, I thought about going from a PC into an external DAC into my preamp. I've been told that this is doable, but not desirable as a PC adds noise to the system, etc.  So, I just don't know where to go from here since I'm essentially limited to wi-fi or a computer based solution. I authored a couple of other threads on this to help with my initial research, but many of the suggestions required a NAS or an ethernet connection, or something with which I'm just not equipped to handle due to a limited knowledge base on the issue; it was much easier back in the day when all I had to worry about were patch cords and logical types of connections. Well, I know enough to know that I don't know.   

Your thoughts and  suggestions would be most appreciated. Thanks.
