That sound good to me. I really love what Grado does well on this phone.
In regards to the drum and cymbal work, I am contrasting that to my experience to how the MTPCs preform. IMO those have the perfect balance, while everything sounds very disproportionate on the SR325is. The detail is there so I hear every snare brush, crash and china, but the presentation is not nearly as forward as the rest of the instruments. It feels almost like Grado is trying to create a false soundstage by making the drums too distant and echoey. Somtimes it feels like the cymbal work that is meant to be feint and quiet sounds annoying and almost buzzy instead of crisp and clear. Like Wind016 said above me, the bass suffers the same problem. Prominence of the Mids and Highs really take my attention off of the Double Bass(kick drums) and make my songs feel lacking. I miss that THUMP and impact that effects the rest of the music! The only reason why I feel like the bass is somewhat presented is because of the clarity and spaciousness of the phone.
I really would like to try a Little Dot 1+ but its not portable. I want to able to interchange between my Coppers and SR325is, but the SR325is don't pair as well with solid state amps(right?). My iBasso T3 will have to do for now.
