I recently bought the Hifiman Deva Pro headphones.

I can clearly notice an improvement of quality when moving from my MacBook Pro (mid-2012) audio port to the Bluemini R2R via USB cable (besides Bluetooth, the Bluemini can work as DAC with 24 bit, 768 KHz, 120 dB SNR, 0.0022% THD according to the manufacturer).
Based on this experience , I would expect even better performance by using a dedicated DAC/AMP. I understand that the DX3 Pro+ is a highly regarded option, but I see some question marks about driving low impedance headphones. The Deva Pro has a 18Ω impedance, but relatively low efficiency (93.5 dB).
Are my expectations of improvement by using a dedicated DAC/AMP reasonable? Is the DX3 Pro+ ideal, or should I look at something different?
Thanks!
