Lumin or Aurender

+1 on @three_easy_payments.  That's not a bad deal.  The A1 is a model above the T2.  I have the T1 and I've been extremely satisfied.  There isn't going to be substantial sq different between the Lumin and the Aurender - they're both great streamers/dacs.

My vote for Lumin. It gives you more options with streaming services. Lumin supports Tidal MQA decoding, Aurender don’t. However, if you live in Russia doesn’t matter...unfortunately Hi Res streaming services does not exist in Russia. 

Lumin T2 is awesome.  A couple things not mentioned yet - Lumin offers huge flexibility in upsampling and downsampling (not sure about the others in this regard) and a bunch of other settings options that are very useful.  Second, I think some might be put off by the fact that you have to have a separate storage somewhere for ripped CDs.  If running Roon and using WiFi, get a laptop that meets Roon basic specs (about $400), put it in a closet near your router, rip all your CDs using something like DBpowerAmp (very simple), and now you have a streamer/DAC (Lumin) that has no moving parts !  Arguably moving parts can break, and/or affect sound quality.  Roon servers IMO are just expensive computers.  Running the Lumin via WiFi is simple, no noise (fans, hard drives, etc.), and foolproof in my experience.   Also using this general solution the Lumin U1 mini is a smoking deal if you can forego the DAC/streamer option, then you can continue to upgrade your DAC or play with DAC options as time goes on without having to re-rip music. But again, having owned a bunch of quality DACs, the T2 is really good.

My vote is for the Lumin.I have upgraded from the A1...superb ....to the S1 and will be upgrading to the X1 in the near future. Their support is beyond compare. Peter Li is available via many of the websites to answer and help with any question regarding set up or whatever. Their Lumin app upgrades are great....

I have the NAD M10 and love it.  I have zero connectivity issues using Wi-Fi, though I decided to do the wired route because sound quality seemed a bit better, could be just my imagination though!.  I’m using Zu Omen Dirty Weekenders for speakers and run Qobuz as a source.
