Bluesound vs SOtM

I am a vinyl guy but after living with the Chromecast audio for a few years I finally bought a DAC. The DAC is an Ayre Codex currently fed by a MacBook Air 2011, directly connected via USB. It sounds a bit harsh and flat, although with plenty of detail and great body in the lower frequencies.

I have therefore decided to feed the fact with a streamer instead. My question is this: Has anyone substantial experience comparing Bluesound Node 2 with a SOtM SMS 200 (with the SPS 500 power supply) in a revealing system?

Again, my system is very revealing so even subtle differences between the two will be clear.

I currently use only TIDAL and YouTube but I am interested in differences in hardware of the streaming that affect all uses.

Thanks in advance for sharing your experience,
Fred

Thanks for your response! I am using the Codex in USB mode. That means a fixed output volume.

What are attenuators? Please explain

PS. I just read somewhere in another audiogon thread that it helps unplug the power supply for the MacBook while playing. This seems to be true.

Besides, I tried to feed the DAC with a MacBook Air 2011 and a MacBook Pro 2016. The difference is huge, enough to convince me that the USB source is a key variable

sotm can be finicky where the node will be very simple in using. the node has its own interface to use where sotm is only a bridge to other interfaces. I have both and the node is my backup if im having trouble with the sotm. You will want a Mac mini or something connected to the sotm at all times on as it can be finicky if the computer connected to it is turned on/off a lot. I keep  my MacBook in sleep mode and it seems to do the trick. Im also not very computer savvy and know the basics' wish I got an surrender if I could go back to have the ease of use.

Wait up. The Codex can be used in preamp output mode with USB input; that’s one of its features. Check the manual https://www.ayre.com/wp-content/uploads/2018/05/Ayre_Codex_Manual.pdf

You’re making the assumption that the brittle sound is due to the MacMini source, which might be the case. However, it might also be that the Codex is to blame. I’d try to determine which (if you can get something alternate on trial or loan).

In the meantime, try running the Codex straight into your power amp using its preamp mode; you will find out if it’s a Codex issue with your preamp, at least. Most Ayre gear (well not just Ayre) also sounds heaps better using balanced outputs.
