CAT SL1 Signature, How does it measure up ?

I am considering replacing my Coincident Statement Phono stage and Dodd Battery Variable Gain Pre-amp with a CAT SL1 Signature.

My best guess is that this will be an upgrade in my line stage and a downgrade in my phono stage side of things, and save me 4000$ which I can put towards upgrading my speakers.

But that is just a guess, the SL1 Signature is pretty old maybe it does worse than my current setup. Does anyone have any ideas on which direction this change will take me ?

Rest of system:

Coincident Dragon 211PP Mk 2 - monoblock tubes
Rega RP6 + Shelter 501 Mk 2
Vienna Acoustics Mozart Grand speakers
Triode CD4SE Vacuum tube CD player

This whole thought has been triggered by the fact that I thought I would be happy with the passive line stage (for the CD player) in the Coincident Phono, but it really sucks in my system.
