I just completed a month-long comparison between a Chord Qutest and my Benchmark DAC3 HGC. For background, I use a full stack of Benchmark stuff: their HPA4 headphone/pre amp, two monoblocked AHB2 power amps, front-end feed from an ethernet-connected Bluesound Node 2 streaming TIDAL and Qobuz. No MQA here. Senn HD800S phones.
The gist of it: I was thinking early-on that I really preferred the Qutest over the DAC3 - at first I was going back and forth between them, but then settled on about a 3-week Qutest-only deep dive. At that point, I went back to A/B'ing the two DACs, and after all that, I unexpectedly discovered that I definitely preferred the DAC3 when it came to headphone listening. This kind of surprised me. The Qutest (using either of their Incisive filters) sounded a bit bloaty compared to the DAC3 - the bass was less defined, and it tended to cover up some of the finer details and clarity that I've come to value with the DAC3. For speaker listening, again, I now preferred the DAC3, but with not as wide of a margin over the Qutest as I experienced with the headphone listening tests. So I returned the Qutest. Maybe my conclusions had something to do with the notion of how the entire Benchmark stack synergizes with their components - not sure. But the difference - over time - was pretty noticeable for me, and I prefer the DAC3.
And I remain open to exploring other DACs in the under-$2500 category.
