Servers: Are we there yet?

I am late to the party, but glad to see this topic discussed by new and old computer audio users. 

I am am a new convert, and chose an all out assault with the purchase of a Lumin A-1 and Synology NAS. It took 3 painful weeks to get all my 300+ CDs ripped with their associate artwork, but I am now more than happy with result. So much so, that I sold my SACD player.   I also use Tidal, an excellent source in my opinion. I sort of hate paying for music via a subscription this way;. I would rather own my music outright. However, I am able to now enjoy music I would otherwise would not consider because things are now so convenient. 

I see there are a few Aurender users here. Are there any Lumin uses, or does anyone have an opinion on either of the systems?

@ben2300 Actually I started out with a Lumin D-1, and upgraded to the A-1. It of course has the external power supply, and I used a Synology NAS. Need to choose a backup option now.  Loving the convenience and sound quality. 

I will ill be interested in your thoughts on the U-1.
