Thanks for your input everyone. The lower priced Sony looks interesting, esp the battery time, coming from the appalling battery life of the Calyx M. Will have a listen to the mojo also and the AK's this week.
I definately agree the ideal dap for an individual is a matter of personal preference however with the high sensitivity of the Zeus I don't want to get something now that will make the Zeus hiss too much. Thanks.
WM1A + Zeus R gets green lights from me
It's lil hissier than Cowon Plenue D and Onkyo DP-X1, you can distinguish it on pause or with just iems plugged in, but once music plays, I can't notice it from the recordings own noise.
In my scaling I rank the wm1a on par with fiio x5ii
From worse (hissy) to quiet black background, rank of the DAPs I tried:
Tier 3 very hissy, will hear with music on play, distracting
Fiio x5 : no go
Sony zx2: no go even if bit less than x5
Tier 2, can hear it on pause, but won't be noticeable on play
Fiio x5ii: good to go
Sony WM1A: good to go
Tier 1, can't notice on pause, can't detect on play
Onkyo DP-X1 : when paused on a quiet silent environment I can actually feel it over my permanent minor tinnitus but it's so ridiculously not distracting I still put it in tier 1. It was this lack of hissing aspect that made me sell the ZX2 and keep the DP-X1.
Cowon Plenue D: for the life of me I never was able to distinguish any hiss from this lil gem of a DAP over my tinnitus when paused or just plugged.
Edit: had Fiio X7 during the tour, but only with the first stock module which was a nightmare for noise from EMI but was otherwise between tier 2 and 1. Never got to test it with the balanced module or the sensitive iem module.
