Well, my Verite open has more or less replaced my HD800…but the HD800 has that unique wide sound stage and imaging.
The closed is similar to the open, just warmer. I think the Eikon will have better bass, HD800 will have better stage.
The Verite Closed is the better all arounder in my opinion. But ultimately it’s your decision.
I use the closed with my Cayin N6ii just fine but it’s a pretty powerful DAP, I’m not familiar with the iPod or amp you have but if it powers your HD800 well then it should power the Verite closed…
