Affects transparency most.After a certain point, how a DAP sounds with your other gear may be more synergy related. The M6 PRO AKM sounds better than FIIO M15 and AK380, my last 2 DAPs. Not saying M6 Pro will outperform those DAPs with all gears. I only use Westone ES60 CIEMs. It takes so little to drive and is very sensitive. I often find some "high-end" DAPs have untamed noise level. That alone can be very distracting and affect sound quality.
