Whew !! we've been testing them for more than 3 months . I own hugo and hugo TT , I got Chord QBD76 HDSD from my friend Elzio and we make compression for 2 weeks . We tried the three dacs with High end loudspeakers and many headphones , the result was :
1- Chord QBD76 HDSD: Tonality : 98 - Bass performance : 94 - Mids : 96 - treble : 95 - Soundstage : 95 - Separation : 93 - Dynamic sound : 94 - Detail : 97 - Tiny detail : 97 - Vocals : 95 - Emotion : 94 - Realistic sound : 95 - Musicality : 94 .
2 - Chord Hugo TT : Tonality : 93 - Bass performance : 93 - Mids : 93 - treble : 94 - Soundstage : 94 - Separation : 93 - Dynamic sound : 93 - Detail : 95 - Tiny detail : 92 - Vocals : 93 - Emotion : 92 - Realistic sound : 94 - Musicality : 95 .
clearer than hugo by about 7 %, more separation between instruments , black background which allow you to hear more detail, richer sound than hugo but far behind Chord QBD76 HDSD.
3 - Chord Hugo : Tonality : 92 - Bass performance : 93 - Mids : 92 . treble : 93 - Soundstage : 93 - Separation : 91 - Dynamic sound : 93 - Detail : 95 - Tiny detail : 92 - Vocals : 93 - Emotion : 91 - Realistic sound : 94 - Musicality : 95 .
Still the best portable dac/amp , can be used as a desktop dac , very clear , warmth sound , sometimes it' sound clourless .
I can't wait for the new model of Chord QBD76 HDSD, I really hope Chord company will keep the tonaltiy of Chord QBD76 HDSD and improve it further more , it's really a unique product . I can't write a review about each product But I'm trying to give hints that may help you .
