I would simply recommend using an amp that will be able to properly drive your HD650 (not an easy task, I might say; just because it's loud doesn't mean it sounds good), and switching IEMs or amping them with something else.

and in this case, adding an impedance adapter might actually increase bass response and smooth the highs, which seem to be the OP's major complaints.

for the $10 it would cost to make the cable, it's a pretty low-risk investment, and should at least be considered before throwing more money at yet another amp, imho.

also, i'm not sure if switching $1150 custom fit IEMs is going to be an option for the OP.

A newcomer to the home Headphone amp offerings, the KICAS Caliente - offered by Purity Audio (a pair of Head-Fiers), is excellent with my HD650 and my SE530's (low impedance, high sensitivity IEMs). This amp brings out the best from both of these fairly different phones.

I am listening to the HD-600's, RS-1's, K-701's as well as Ety Er-4's through a Singlepower Extreme. I haven't seen a better amp under $1000.
