I have a Focal Elex, Beyer 880 at 600 Ohms and the Senny HD 650 and I'm looking for a headphone DAC / AMP around 200$. I have sensitive ears so the amp does not need to be powerful.
Currently I have a Chord Mojo that's unreliable (shuts down randomly, battery doesn't charge at all after 18 months, etc.)
Looking for something without battery as I found out that battery and heat produced by DACs do not mix very well - it shortens the life of the battery.
What are the latest greatest in this price range, please? Much appreciated.

So far I found

The DX7s' higer output impedance isn't as good a match with the Elex.
But it is close enough to most likely not matter. It just squeaks over the 10x rule. DX7s - 10 ohm, Elex = 80 ohm. Still, the nod goes to the DX3Pro.

You sir just made my day by pointing me to a battery source for Mojo. IF that was the ONLY problem with my Mojo I'd pay 80$ for the battery - and yes I can handle a screwdriver and hot-glue gun :) Now I am tempted...
My Mojo gets warm, but I obey the 40% rule and never charge while listening, and the battery has lasted a good while. Still, new gear is FUN.

Hmm - DX3Pro vs JDS Objective2 Odac Combo Revb so far it seems.

D10+O2 (my setup) is somewhere near $200 and is more powerful than DX3Pro.

DX3Pro’s only got 2V 6V of output into 300ohm, which I guess won’t be adequate for 600-ohm Beyers, but the Senny be fine (My 250-ohm beyer still needs more than 1x gain from 2V DAC for quiet tracks).

edited: Anyway I also plan to buy DX3Pro as its DAC performance is superior and it has nice bluetooth functionality and digital volume control.
