I don't doubt that the SGM Extreme is a great server streamer but dual Xeon processors and 48 gigs of ram? All you're doing is storing and streaming music not 3D rendering and VR design and video editing, isn't this thing a bit of overkill?

high end audio and attaining suspension of dis-belief do require headroom and overkill. that is where ease and naturalness and escape from a digital signature come from.

please go to the thread i posted the link to and start reading. i don't have the techie chops to make the technical points, but every possible question and challenge is posted and responded to about servers in general, and the Extreme in particular.

DCS Bartok is by far the best DAC in your price range. It is the most affordable derivation of the Vivaldi stack. I really suggest you listen to the Rossini, just above at $24k, but that one is magic. The Ayre QX 5 Twenty is really nice at $10k. However, I don't think vocalists really sound human short of DCS. At these levels, you want a vendor who will be around in ten years, so think twice about the touted in forums only brands.

Ufguy - I am in a very similar situation looking to upgrade my DAC / streamer. I haven’t used a CD in probably 3 years and use Tidal HiFi and masters.

in terms of sound, for an all-in-one unit, the Linn Klimax 3 with Katalyst DAC is very good. The DSM version also has volume control and HDMI pass-thru so can also work some A/V scenarios vs just audio. It runs in the low $20s. I auditioned the Linn against dCS Rossini and I felt the Linn beat it (for my taste). I also auditioned the Klimax vs the Linn Akurate, which is next tier down for Linn. It took all of 5 seconds to hear the difference between the Klimax and Akurate (maybe $8-9k). The downside with Linn vs others is likely on formats they support. My understanding (others in forum who are deeper jump in or correct) is that Linn does not support MQA (masters). So, before you pull the trigger, it’s worth doing some diligence on formats and your music choices on the streaming service you choose.

I have been trying to audition the Aurender A30 ($19k), Lumin X1 (13k I think) and MSB Premier with renderer module, which allows it to stream ($19k for the DAC and then add-on pricing for the renderer module).

it is a PAIN to find a dealer that carries all of those lines. MusicDirect is an online option that gives you 60 day money back to try it. They carry Aurender and Lumin

good luck
