Which High-End preamps have these 2 features?

Sonic Frontiers 1,2,3 Audio Research LS-25, VAC just to name a few.

Thank You for the replies.

How about a Boulder 1010?

VIOLA Audio Labs CADENZA or SPIRITO (Modular preamp).

Viola amps are nice but I believe Cadenza doesn't have a remote and the Spirito is way too expensive.

I'm leaning towards Boulder since the power amps will be Boulder. I'll also try ARC Ref3 and hopefully a VAC Phi before I order anything.

Anything else worth considering?

The Conrad-Johnson ACT2 includes two pairs of inputs that offer unity-gain support for an external signal processor.
