I don’t know about the two you mentioned, but I’d compare them to something like the Schiit Magni amp combined with the Modius or Modi Multibit DAC — I much prefer separates myself. For a cable I’d do this — 6N copper and Neutrik plugs, and the Hifiman version with 3.5mm connectors should work with your ‘phones.

Just another idea FWIW, and best of luck.
