Hi,
I really need your opinions and help here.
I am with the Mojo and HD650 for 7 days and more, but I still didn't like the Mojo at all with my cans.
I listened to it not too much (say one hour at day) and I listened only it in these days without AB test with other hardware (as adviced here).
Yesterday, though, I did two AB tests... one with my iPhone 8 Plus and the other with my Asus Essence One desktop dac.
iPhone 8 Plus vs Mojo
Is really hard to spot differences at normal listening volumes! Sure, the Mojo is overall better and can "drive" the HD650 louder than the cheapest dac of the iPhone, that's for sure, but really, the iPhone performarce is very close to the Mojo's and I am speaking also in the dynamic range department!
Asus E1 vs Mojo
Here comes the pain! I listen a very HUGE difference in terms of SQ between the E1 and the Mojo with my HD650... the E1 drives the cans much better than the Mojo. If with the latter I have more nuances in the voices and maybe the middle are little forwarded, and I could say there are some more details in the Mojo presentation, the E1 gives a dynamic, punch, slam, call it how you want, that the Mojo can only dream! And I am not sure it's only distortion... I think the E1 "fill" better the HD650, it makes shine the middle-bass department, it has more body, it more... felt on my ears. The Mojo, instead, need to me that I increase little the volume during the playing, and even that, I can't feel the dynamics that I need with the HD650.
It makes sense to give the Mojo other days for breaking in? It makes sense to try the Mojo with LOWER impedance cans instead that with my HD650?
I am thinking to buy another E1 (maybe newer versions) and put it in my bedroom (iPhone>Tidal>E1>HD650) and returning the Mojo back... still thinking.
Instead, the Mojo as Dac seem far better than the E1 in my main system, it more "organized" the image that I get from it, but today I will play back with the E1 to understand better the difference with the Mojo. Maybe I could keep the Mojo as first dac in my main system and taking the Asus E1 in the bedroom only for headphones playing.
Advices?
