The concero is a little more musical linear and detail and music is more full with more body
After a while The differences are a bit more clear but it's not a day and night ..
Does it worth the money? I don't know.. You know money and upgrade aren't aligned in this hobby
The two up sampler filter are very very similar
I wasn't interested in dsd too and in balanced output as well ( in this moment)
I tried the mdac before for a week
It sounds clearly different from hrt. More detailed and it seems that you hear more information from the music. But I think in my setup, that is pretty warm, it miss a bit of musicality:too much detail
I listen this setup far away from home where I work and from the laptop only so for me it's perfect for Connectivity and moving easiness
Next week I hope to have the chance to listen the psaudio nuwave and naim dac in my setup
We ll see..
