Hi Sorrodje,
I've received a Hugo for testing purpose last saturday. Tried yesterday as a dac/amp. The worst point is the soundstage with an obvious lack of center/focus and a serious lack of depth. Very Left/Right. Overall a bit lean sound with treble glare too. Bass department seems OK to my ears though. I wouldn't advice the Hugo as a good dac/amp for HD800.
Didn't tried the Hugo as a standalone DAC associated with the LP G103 or my Sonett 2 yet. Will compare it to my Metrum Octave mkI and My Beresford Caïman mkII.
I've been waiting for someone like you (someone who I perceive as having a nearly "ideal" chain for the HD800), to post impressions on the Hugo > HD800.
I can now remove the Hugo from my list of high-end candidates for the HD800. Thank you!
Your experience (and contentment) with the Metrum Octave MkI and DNA Sonnet 2 gives you a lot of credibility in my book, when comparing the HD800 with other gear.
I honestly believe that many HD800 owners have never heard what it can do. If they are content, I would still argue that they may be content in ignorance of a better experience. Adaptive hedonism has not yet taken them as far as they could go with the HD800.
I enjoyed a twenty-minute glimpse into what is possible with the HD800 at a Head-Fi meet, with jazzerdave's Cavalli Liquid Glass setup, and I know that I am currently equipped to achieve only a distant approximation of that experience, but my relatively modest NOS Octave MkII and single-ended, low-feedback, Class A NuForce HA-200 setup is much, much closer to what you and jazzerdave have, than what I hear with any oversampling DAC or mutli-stage, high-feedback, push-pull, solid state amp (like the OPPO HA-1, with its excellent for LCD-2 and PM-1, ESS9018 and 1817mW into 50-Ohm balanced amp.)
