Preamps

I'm not unhappy with the Jeff Rowland Corus preamp,  but I don't know what I don't know. I'm currently looking for a solid state preamp with HT bypass to compare to my Jeff Rowland Corus preamp. I would like suggestions below $15K new list price to listen to. I have a Jeff Rowland 625 S2 amplifier, Antipodes DS GT music server and Chord Dave DAC.

ARC has a fact sheet on their website expressing concern about the tube preamps driving a main amp plus sub. it’s in black and white unless they pulled it. it killed a ref 6 deal for me.,

georgehifi, ricred1,4425,

It was very hard to find on the AR website but this is the link. Odd though that the AR rep didn’t know this...
This also kills my plans for using a tube preamp.
