@adasdad I still have the M3. It’s kicking butt right now with my new streamer.
Where it wins over the qutest for me…
Lower noise floor due to good power supply design and implementation. The SMPS like the one used on a Qutest can potentially pollute the AC impacting the performance of other components.
More natural, relaxed presentation with fuller mids, deeper soundstage, sweeter treble, more bass presence that has more texture along with better drive, more subtle details are revealed, requiring less effort to hear what’s on the recording. But at the same time it’s never in your face.
XLR outs. Much better ergonomics. AES/EBU input. Excellent USB implementation. Two different clock settings. 4 filters. Native DSD via USB. Awesome built in preamp(not an oversight at all…it can hold its own if you’re in between preamps).
