In the portable world Hugo made a big name for itself due to its sound and options, but the price was always a challenge, especially to people like me, who believe that desktop gear can be obtained, which can sound significantly better than the Hugo at the $2500 (Then) price point. Another factor that proves Hugo is kind of a middle of the road product is the portability factor, no person in the world can enjoy the music while busy holding that beast on the go.
To me QP1R bridged that gap. I've been using it for 3 months now, and I've not manipulated the EQ with any of the headphones/IEMs I have in my inventory, as it sounds that good in default.
Giving it a considerably small amount of time in daily use (a week at least) one can easily get addicted to the sound signature as it is basically having deeper extension in the bass & highs and a flatter mid range compared to the MoJo. Advantage of space, portability and practicality of carrying one device kept me out of getting into Hugo and later MoJo for that matter.
Now as a DAC I personally feel that the Resonessence Labs Concerto HP/HD does a better job than the Hugo, if you consider Hugo as a home/travel use category gear.
The sound you are getting when you combine any DAP with an amp is the sound of the amp.
Now about the desktop rig, I agree, my reference dynamic rig Amarra 2.6 /Audirvana PlusPlayer, HiFiMan EF6, Dr DAC DX-2, Sony MDR-CD-3000 and the Piezo Electric Rig Taket H2+, TR2, Yamaha AS-500 and QP1R sounds better than anything I have on the go. But when I want that sound on the go, the Class A amp of the QP1R gets me there very close to the dynamic rig, as except for the sheer power of the EF6, the QP1R has more resolution and depth on its own.
Read this and you may have a better idea of what I'm talking about.
looks like I need to audition questyle if i get the chance which will be difficult.
to me it appears people are bored of simple desktop amps like $250-300 solid state desktop amp. none of those get any hype these days. to my ears, those sound the best.
