Aesthetix Callisto Signature


Are there any changes in the Callisto Signature or the preamplifier remains the same?
Is there a sonic character? How it compares against CAT Ultimate SL1 or Lamm L2?
Thank you.
Apopira2 I believe the Caps have changed the sonic character of the preamp. Much bigger btw.

I was interested in the Calyspo Signature and I found more information on the Callisto Signature.
