From my experience over the last few years I find the SPM IC I have dark, can I say suppressive? I use it on CDs that I find much too aggressive/bright. I feel the SPM IC filters out alot of "noise"? Part of the situation here is that listening to the Vallahas has change my perspective of cable performance.
The Vallahas are in another league. Very clear maybe too clean; seem to be a bit too much on some guitar pieces at the very high notes. And aging hearing is not helping. Very good on classical pieces. The SPM and Vallaha do not work well together in my experience.
I can add that a pair of Black Knight ICs from the mid 1990s has been very relaxing and one that I am keeping. Not the greatest detail.
