Few days ago, I demo-ed Fiio X7 and comparing it to my Plenue M. At first, (IMO) the detail on X7 beats the M, separation is par on both players, the highs on Fiio sounds a bit metalic, dry vocal and recessed mids. The M wins on natural voice and timbre and the Fiio wins on details retrieval and greater imaging. Both players has weakness.
Spoiled by the X7, I came home overwhelmed by Fiio's detail retrieval, the M felt softer. At the sametime, I play around with the M, I turned on the BBE setting to 7... I was shocked. The M is no longer soft, its capable to bring out the details I was talking about. The music feels more alive, detailed and more engaging!
I always put my Plenue M on normal EQ, with the EQ, BBE and all those settings, Plenue M is truly a versatile and capable player. I was thinking to sold my M and buy X7, but not anymore
