Portable amp/DAC or desktop?
Your budget?

I started with iCAN to drive the HD800 and decided enough was enough after few weeks with the combo.
The DAC was also the cheapo AudioEngine D1, so I know the amp and DAC were the bottleneck.
The high just too piercing and rough, even if I switched on the 3D bass boost on the iCAN.

Right now I'm using Oppo HA-1 running balance out to my HD800 and LCD-X, both using WyWires Red balanced cable.
While I do like the power and authority of HA-1 in driving the HD800 and LCD-X when fed with DSD or Flac, I still find that there's not enough weight in HD800 bass.
I do like the HD800 sounds when I demoed the them with Alo Studio 6, wired with Alo Ref 16 cable, but the price of the amp or any other tubes amp that can do justice to the HD800 and a decent DAC that can play DSD makes me contend with the HA-1 since the HA-1 is already an excellent pairing with the LCD-X.

No DAC can accept analog signal from your headphone out.

Honestly speaking bro, if you willing to spend RM 2-4k for a DAC but still keep the HD600 as your cans, maybe the HD600 will be the bottleneck.
To me, the biggest difference in sound comes from the transducers, be it headphones, iems or pseakers.
If you like HD600 sound signature, maybe you can try auditioning the HD800, AKG 812, HE-560, etc.

I did audition Yulong DA8 but it doesn't have balanced headphone out.
I tried it with my HD800 but to me the amp part is so-so only, so did not proceed further.

The owner of the Yulong told me he prefers it over the more expensive Mytek 192.

I plugged the Roxanne direct to the 3.5mm AK100II jack as I values total portability.
I tried the 2.5mm balanced out but the sound to me just lacking the dynamic, maybe because AK100II balanced out has less power to the single-ended, as opposed to the AK120II and 240.

I have not tried the JH11, so no idea about the sound.
As for the 13, 16 and Roxanne, truth be told I much prefer the 13 sq over the other 2.
I jumped on the Roxanne due o the 2013 Black Friday discount but the waiting period of 8 months for the carbon fiber ciem left a bad taste in my mouth.

SQ wise, the Roxanne is a bit warmer compared to the 13 due to the smooth high and thicker mids.
The 13 sounds energetic, and almost neutral except with a bump-up mid bass. The treble is much clearer, with morr sparkles compared to Roxanne.
The 16 has too much sub bass for my liking, making it almost sound like a V-shape.

Do upgrade your earphone. You will notice more change in the sound quality, rather than spend it on DAC/amp.
Do state your budget and preference in the sound signature, i.e. bassy, vocal-centric, clear, etc
Easier for others to help

No budget?
Can try Oppo HA-1

You have to decide if you want a portable amp to go wih your DX50 or a desktop amp?
