I’ve heard the Moon 280D streaming DAC compared to my Pro-ject Stream Box S2 Ultra streamer with a Chord Qutest DAC at a dealer last year. The Pro-ject/Qutest combination was quite a bit better sounding than the 280D in terms of conveying rhythm and musical detail. The difference was immediately obvious. Music from the Moon 280D was smooth and not harsh, but it didn’t move me.
As good as the Qutest sounded, I now have a Denafrips Pontus II DAC that sounds even better (better detail resolution, richer tonal quality, warmer in sound, more natural sense of rhythm and pace). I had purchased the Qutest used as a known benchmark for comparing to other DACs. If you’re trying to warm up a cool sounding set of speakers, the Denafrips would be a good choice. Though you would have to order one, it sounds as though you also don’t have brick-and-mortar dealers close to you to listen to one first. The Denafrips DACs are selling like hotcakes and I see that folks are selling used units for close to full retail price as there is a waitlist for new units.
The idea of an integrated streamer-DAC is appealing from the perspective of simplicity, but finding one that sounded good to me was a challenge. I also listened to a $8.5k Naim NDX2 streamer DAC that wasn’t appealing in sound to me.
In terms of price, the Pro-ject streamer runs about $850 new and about $450 used. The Denafrips Pontus II DAC is about $1750 based on the current exchange rates from Singapore dollars.
