I promised a couple of people who pm’d me that I would write up some comments on the Hugo TT 2 that I was among the first to receive. It’s taken a little longer than I expected but here it is
First, some context. I listen exclusively to headphones, mostly to Focal Utopia with Prion4 cable but also to HE1000v2 (also with Prion4) and LCD-4. I listen mainly to the various forms of classical, jazz and acoustic music. In striving for the best sound I can get within my means my priority is clean detail and then getting as near to authoritative natural tones as I can without significantly compromising on detail.
My full system is set out in my signature but I thought it would be useful to most of you if in comparing the Hugo TT 2 to my DAVE (with and without the M Scaler) I kept things simple, so I used my AK380 DAP (running off battery) connected via optical as the source. DAVE, Hugo TT 2 and M Scaler all used the supplied bnc cables, power cables and power supplies. I also used the supplied cables with each of the headphones. Everything was plugged into a Shunyata Venom UK6, which in turn was connected to the wall socket with a Shunyata Alpha HC cable.
The Hugo TT 2 is a very fine standalone dac/headphone amp. It concedes some detail (still very good detail), transparency and depth to the DAVE but offers more weight, a more natural tone and generally lends greater authority to music playing through my headphones.
Using the TT 2’s low gain setting, which I assume to be roughly equivalent to that of the DAVE’s output (Rob?), music was already more natural sounding, warmer and a little more authoritative than with the DAVE. But switching to high gain increased weight and authority even further, and with little or no sacrifice. It did this with all three headphones, even the relatively easy to drive Utopia. Only rarely did I prefer low gain to high gain, and only when I felt a track would benefit from slightly more prominent detail and air. I would expect most who have a DAVE and feel they need a dedicated headphone amp to properly drive their headphones would not feel that way with a Hugo TT 2.
The M Scaler elevated the TT 2 in the same way it does the DAVE - more presence, realism and smoothness - but the differences between DAVE and TT 2 were still there. With TT 2 on high gain, I was almost out of my seat imagining myself playing all the instruments on the jam-like ‘Blues for Los Angeles’ from Bill Frissell’s Gone, Just like a train album. The saxophone on ‘Forever …’ from Andy Sheppard’s album Romaria was simply haunting in contrast with the double bass. The brass sections in part 2 of Malcolm Arnold’s second symphony (with Richard Hickox and LSO on Chandos) were dynamic, clean and soaring. There was a believable weight and sole to Sol Gabetta’s cello playing in Elgar’s cello concerto. Piano playing on numerous classical and jazz tracks had believable leading edge weight. Antonio Forcione's latin jazz guitar playing on his live album was suitably weighty, tight and dynamic.
It will be a matter of personal taste but I felt the Utopia and HE1000v2 were particularly good pairings with the TT 2, especially the Utopia, which benefitted from the extra warmth and body. The LCD-4, which I am not getting on that well with at the moment, sounded a little too warm with relatively low levels of detail, and there was still that prominent upper-mid/lower-top issue that can sound quite off-putting with (for example) classical music and saxophone/trumpet-led jazz, if less so with rock.
Frankly, the Hugo TT 2 was good enough to cause me to think carefully about what DAC I preferred. Ultimately, and given my preference for detail, it still has to be the DAVE (just), which I feel I can add (and am already adding) some of the qualities of the TT 2 to with improvements to other areas of my system. But if the TT 2 had come out first and I owned it along with the M Scaler, I am not sure I would then have felt the need to upgrade to the DAVE.
IMHO, those thinking of buying a Hugo TT 2, either as a stand-alone dac, or with the M scaler, can do so with confidence. Having owned a Hugo 2 for a few months until trading in earlier this year, I can say that the Hugo TT 2 kicks that into the long grass for over-ear headphone use.
