Lumin D1, has anyone heard it?

WorldwideWholesales is spot on with his evaluation. And I don't know him from Jack. I am just here reading treads and came across this. I had a Lumin D1, and upgraded to the A1 within a few months, sold my SACD player, ripped all my CDs and SACDs to a Synology NAS (one of the options recommended by Lumin), and haven't looked back. It really is that good and a game changer as far as I'm concerned.  And I am not biased for digital, I still spin two TT and own a boat load of vinyl. 

The really nice things about this server is it's not fussy, clean in design and to look at, sounds great (it doesn't even sound like it's digital), and you have a universe of music options (internet radio is free, TIDAL DSD, and you own music library (my CDs are boxed up in storage). BTW, my CDs sound better than they ever have ripped to my NAS and streamed to my LUMIN via a CAT 6 cable. 

I use  Wireworld hi-quality balance cables, a hi-quality after market power cable and Stillpoints for isolation. 

WWW...what CPT pc do you use on your Lumin..?..

which input of Lumin provides better sound quality - Ethernet or USB?

I have a Lumin D1 for a month and is very happy with its performance. It plays flawlessly, and in many ways better than my $4000 tube CD player.  It has pin point imaging with great width and depth. Sounds very analog to me.  Noted that I also replaced the factory supplied switching PSU to HDPLEX Linear PSU. 

I recently installed a NAS drive (Synology DS-216+ with 4TB Seagate drive) and minimserver for streaming.  To compare the  sound quality between Ethernet and USB inputs, I ripped a few CD to both NAS drive and USB thumb drive. After spending an evening of critical listening of the two inputs with the same test tracks, I think the USB input sounds more dynamic and has better imaging.  Not a big difference but noticeable.  My NAS set up is only a week old, and perhaps it needs more time to burn in? 

I would appreciate if you can share your Lumin experience about NAS drive Ethernet streaming vs USB thumb drive.

I have the A1. However by USB will see a thumb drive with digital file, but my Lumin will not play it. How did you get yours to work? 

Ripping CD to USB drive should be very similar to NAS drive.

In my case, I use dbpoweramp to rip CD to my PC.  The file directory folder structure is typical \artist name\album name\track name. I ripped CD  in FLAC lossless. I then coped these music folders in both USB and NAS.  

In my set up, I inserted both the USB stick and Ethernet cable to the Lumin.  The Lumin app on my iPad shows the album artworks from both sources.  I can play the same tracks from both NAS and USB stick to do an A/B comparison.  I also ripped WAV and AIFF in separate folders, and they all show up in my Lumin perfectly fine.
