I'm posting in this thread (as well as in the HE 400s Headphones thread) my initial impressions on the Oppo HA-2 paired with the Hifiman HE-400s headphones, in case anyone is also considering this combo.
I received my HE-400s headphones last week and have enjoyed them a lot. I've mainly used them directly from my ipod or from my iphone 6 (spotify) or computer, most of the time paired with a Dragonfly 1.2. I'm no expert on how to describe the "sound", but I can definitely say they are way above all my previously owned headphones (Bose AE2, Alessandro MS-1 and Sennheiser HD598). Sounds from instruments feels tighter, clearer. I play drums and on several acoustic songs the tom hits sound extremely real (as if I was physically on that room). In short, I'm very happy with the purchase.
So, yesterday I received the Oppo HA-2 portable amp/dac. Even though I plan to get a Schitt stack (modi 2 and vali 2) to listen at home, I'm still working on my music source (repurpose an old laptop or buy a new computer, like a mac mini) plus I need a new desk, so I decided to go with a portable solution as I mostly listen to music in bed. Also on the weekends, I can keep an eye on my two kids while enjoying good music. I was only able to listen for about 45 minutes, again using my iphone 6 and spotify. Initial impressions are positive, I felt the bass was tighter, more pronounced, and I liked that. This was while listening to Rock and Acoustic music.
I did a quick A/B test regarding the low vs high gain setting and I "feel" I enjoyed the music more with the gain on high. Anyone can comment on this?
In regards to the bass boost, it was very nice on hip hop songs... on every thing else (Rock/Acoustic/Salsa), it's better to leave it off, in my opinion.
The unit itself is very well constructed, the packaging is very nice too.
Feel free to comment if you have this combo.
