I had GC ICs for years and never thought I would never change. I did, to Zu Varials. The detail levels are awesome now but still not too bright.
I also had neutral ref digital Ic which bested Stereovox VX 2 and X2 -60 digital, but was eventually ousted by Zu Ash for the moment. I find the Ash bordering on too bright but the treble detail is nice compared with neut ref. I still have the neut ref tho ...... Awesome digital IC, warm and cosy and easy to live with.
