NAD M50.2

Hi audiotroy. I don't know exactly what I want. I do not need a DAC. I have a Berkeley Alpha Reference 2 that I Love. The NAD intrigues me both because it seems simple to operate, and that I can easily rip my CDs to its hard drive. Is 2TB enough? I have about 4000 CDs but probably wouldn't rip them all. Once on the NAD, how easily can the digital files be moved off? And I do question the build quality, based on ejr1953s experience. I am also intrigued by the Aurender N10. But I am Not a computer guru, and I don't know how to easily get my CDs on the Aurender. I plan to mainly play CDs, or files of them, and also some high res. downloads. I won't stream music much, if at all. Thoughts?

I posted earlier, but I think I made an error so I just decided to redo it. 

I purchased an M50.2 recently. I was also looking for an “all-in-one”
streamer option, and was debating between this, the Aurender N10, the Aries and the Nimitra. 

In the end, even though the M50.2 doesn’t support DSD, it still hit 90% of the other stuff I wanted. It rips CDs nicely. The software (BluOS) does a good job with the metadata and CD covers, but the files are acessible via network shares if you want to do more.  Along with the conventional stereo digital outputs, it also includes HDMI for multichannel audio (assuming you can find some) but it’s nice to have the option.  It will back up data to an external HDD. The BluOS app on the iPhone works, but if you want to go with Roon instead, that’s always an option. 

The sound quality is good, and the unit is silent. No complaints there. If you need any other information, let me know. 

I know this is a tough or unanswerable question since you bought the NAD, but do you suspect the sound quality is as good, as say, Aurender through a great DAC? 
And I am pretty computer illiterate when it comes to computers in audio systems, but once CDs are ripped to the NAD, is it easy to move them off?

Take this with a grain of salt, but if you’re using USB, then as long as your DAC is using asynchronous USB and your data is clean (the NAD performs error checking when ripping...if the track’s checksum doesn’t match the metadata on the CD, it rescans) then, well, data is data. I don’t see how any digital source can be any better than the other, especially if you’re processing the PCM through a standalone DAC. 

As I mentioned, the NAD mounts network drives, so all you need to do is scan your network on your PC and the drives pop up.  You can, if you choose, to simply drag and drop the files from there or attach a USB drive and go to the BluOS app and select backup, which will make it mirror the internal files to the external USB drive. Pretty easy.
