Cable upgrade

Maybe look at Headphonia cable reviews here

I know you said to limit cost at $200.  As @blisshifi stated the Arya Stealth can sound tipped up and requires a cable with a very balanced  frequency response.  I recommend listening to WyWires Red, one of the most balanced, detailed, dynamic cables I have owned.  Images are dense and staging wide.  True to timbre.  Read pro reviews as well.  Construction is robust and kink resistant.  I owned HP cables twice the price that were feeble by comparison falling apart in just over a year and needing repair.   I have a Red three years almost daily use and it looks new.  Go to www.wires.com.  Alex, the designer and president is sincere and down to earth. Only issue, it’s $349.  If you can increase the spend, well worth it. 

I have HiFiman Sundara Closed. I got a Blue Jeans cable. It sounds great and is well built. A little more microphonic than the stock cable that was too short. They even put on a 90 degree angled plug that works great on my set up. About $120 delivered.

I use Moon Audio Black Dragon cables for all my headphones and am quite pleased with them; I don't know if they're under $200 or not, but they shouldn't be much more if they are.
