I said I would report back on the pairing of the Tera with the DT770-LE, and while they do sound good together, there is not enough volume for me. My Tera is V-0 and the Beyers are low impedance but not such high sensitivity (96db). Either I like music a lot louder than most, or the Tera just does not have enough oomph. At maximum volume the music is just about where I listen moderately, and that does not leave any headroom for when I want a bit more.
However, the headphones do sound very good when I include my little Tralucent amp in the chain. I will have to decide if I keep them and use them this way, or if I try something else as my closed headphones for portable use with the Tera. When I say portable, I just mean going out in my back yard, so definitely carrying an extra amp as small as the Tralucent is no problem. If I start traveling again, I may have to find some iems to use for that, but generally I do not like fiddling with iems if I do not have to.
Overall, the DT770-LE is just a bit more dry and clinical than my HD650s, but that is nice for a change. And I do not find them as overly bright and clinical as the Beyer T1s I just sold. These lie somewhere in between the HD650 and the T1. Although I should add that they are not broken in yet.
And Andy, I am curious, do the ATH-ESW9 have enough volume straight out of the Tera?
