I am with Stanwal suggest on the DL304.
This is taking both carts stock, no mods to the 103.
The 304 improves on being able to decipher complex threads on large orchestral stuff. It is a little bit less thick in the midrange but the oomph is still there. But they are very close in that respect. Load both the 304 and 103 at 40ohms using a SUT and the midrange is very familiar with no congestion issues.
Go there or upgrade the 103 with all it's word, retip, and potting tricks.
