Which High-End preamps have these 2 features?

Thanks for the replies. To avoid any second thoughts I went with the Boulder 2010 Pre and I'm very glad with my decision. It's an outstanding Preamp

Legacy has a preamp with those features but it is actuality built by Coda.

You need to audition the MBL 6010D.

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

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?

VIOLA Audio Labs CADENZA or SPIRITO (Modular preamp).

Thank You for the replies.

How about a Boulder 1010?

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

The Modwright SWL 9.0SE without a doubt....

VAC also

VAC is also an excellent choice.

Asthetix Calypso, MBL 6010D, Rowland Synergy, Dartzeel, RSA Emitter ii

The BAT preamps hit those criteria....any of the inputs can be set to unity gain...which is what your processor input needs...

Too many. The Sim P-8 fits.
