1000+ Head-Fier
This is a long tale of music sources. I had a several weeks shootout comparing and contrasting these: {MacBook, Pro-ject Stream Box S2 Ultra, Allo USBridge Signature, (… eventually SOtM sMS-200ultra Neo)}.
I am sharing my notes in case they are helpful to anyone else. Perhaps it will be a self-musing at most, but I am posting nonetheless. This is all subjective and as a human, I am prone to all the usual biases. I am reasonably detailed in my note-taking and attempts to make "clean experiments". It may still be all psychoacoustic confusion nonetheless.
Device descriptions (all #s are £RRP for reference):
the best my favourite of the bunch was (USBridge+IdeonR3). That said, I am very happy with just the USBridge (i.e.; no IdeonR3) AND A GOOD USB CABLE. I really, really expected the Pro-Ject to be the winner at this stage. I was surprised by this given there are several really positive reviews of it. Granted, they are all comparing to the older USBridge (i.e. not Signature, no Shanti power supply), but still... All my biases were with the Pro-ject. I spent days trying to go back and "see what I was missing" about it, but no matter how much I tried, my ears liked the USBridge Sig w/ LPS more.
But wait… There’s more...
8. [Core] NUC > [Endpoint] SOtM > USB ...
Punchline #2 (my real punchline): … So after all of that was done (and I started this note) I got a hold of an SOtM sMS-200ultra (good used price). IMO It rocks. The USBridge solution without the IdeonR3 sounds great and awesome value for money, and the IdeonR3 adds to the sound. BUT - they did something great with the sMS-200ultra. It works in my setup. For me, this was another shocker because I was "sure" I really liked the USBridge solution as the (?)end solution. My biases were now with that pretty firmly. Lo-and-behold; I really like the SOtM setup.
Something like: 8 > 7 > 6 > 5 > 4 > 2 > 1,3
** The distance between {7,6,5,4} is smallest. Reading the comments, that should be kept in mind.

Device descriptions (all #s are £RRP for reference):
- (£599) Pro-Ject: Pro-Ject Stream Box S2 Ultra with wall-wart power supply. (I can't find anyone really using an LPS on these and I hear the power supply is well done and LPS won't help.)
- (£405) USBridge: Allo USBridge Signature w/ Shanti linear power supply. I didn't try w/o LPS because I don't have a wall-wart for it.
- (£300) IdeonR3 Ideon R3 Reclocker Ideon 3R USB Renaissance mk2 Blackstar edition. I have mentioned this nice little device on the Lampizator Amber 3 thread. I think an LPS would serve this well, but I didn't have one to hand.
- The MacBook Pro was not dedicated to any job, but the device I am actively using while listening.
- All tests were done with Roon, mostly with flac files, but also some Tidal streaming.
- (~£320) NUC Intel NUC (I wanted to move to this a proper Roon core to get that responsibility away from the active MacBook).
- USB Cables: Tellurium Black from MacBook pro (3m cable) or Luna orange (1m) from any streamer. If IdeonR3 used, Luna gris (1m) to the device, keeping Luna orange after. (FWIW - Luna orange is the nicest USB cable I have had in my home setup)
- No advanced router or ethernet cables.
- Eventually I also added this: (£1200) SoTM SOtM sMS 200-ultra Neo with (£330) SBooster Linear Power Supply
- [Core and Endpoint] MacBook Pro > USB ... (The baseline for the exercise)
- [Core and Endpoint] MacBook Pro > IdeonR3 > USB ...
- [Core] NUC > [Endpoint] MacBook Pro > USB ...
- [Core] NUC > [Endpoint] Pro-Ject > USB ... (The one I expected to settle on)
- [Core] NUC > [Endpoint] Pro-Ject > IdeonR3 > USB ... (The one I expected to 'win')
- [Core] NUC > [Endpoint] USBridge > USB ...

Other comments:
- USBridge without IdeonR3 was also very, very good IMO. The better quality USB cable made the most difference in this setup for some reason. It is a solution I would very happily live with and totally recommend it.
- Pro-ject: It did generally sound good, a notch better than my MacBook. Leaving WiFi enabled was audible on occasion so I don't recommend that.
- The MacBook was hard to beat in by a big distance, however on the occasions that it would get busy and get its knickers in a twist, it would stutter. SOtM and USBridge solutions were well-better than the MacBook source in the end.
- The IdeonR3 added a degree of smoothness and clarity to any setup. (I did not add it to the SOtM because I won't buy it all!)
- Lampizator devices have good USB boards (Amanero) so this will be different with a different DAC.
- I have a bias towards having "less stuff" in the chain. Of course, I'd like to spend less too.
