Hi guys I need your help I am trying to get and amp and a dac or combo of both for my DX 50, I want to build my own personal ultimate portable sound gig, but I am not sure which amp or dac to buy. if possible I would like a combo but also I want it to utilize its own components to give me the best sound possible also I am planning to get the HD 650 sometime so I need something that can power up 300 impedance at least. thanks
You need to take note that DX50 has Coax only for digital out to an external DAC. There are not many portable DAC out there that has Coax IN. If you go full iBasso stack look for DB2/PB2 combo. I'm sure it can power a wide range of headphones from iem to headphones. HD650 would be easy to drive for PB2.
But like others have mentioned DX50's DAC is already good and you may only need a portable amp.
Here are just a few that works very well for DX50
-UHA-6S MKII (This one has a built-in DAC with Coax in, but imo not as good as the DAC in DX50)
I list them in the order of the most power it can supply not necessarily the best sounding. I personally tried O2 and UHA-6S MKII (my current portable amp paired with DX50) with HD650 and both can sufficiently drive HD650.
