interesting report, thanks. Holco’s report is earlier on this thread.
My preliminary take is that the CSA is more transparent and resolved for pretty much all instruments and vocals. More open and clear, with notably better microdynamics. I will have more to say later, on the Thiel Owners thread.
But my subjective take should differ from yours. I have a late SE version with XOs sourced from FST. The coax feeds are Clarity SA but all other caps are CYC MKT, which is a lower quality. Also, I’ve been running Mills resistors since May. And my upgrade is a full rebuild with Multicap RTX bypasses on the coax feed CSAs. There is nothing from the OEM boards remaining, not even the coils. So, my starting and ending places are both substantially different than yours.
