I second what @rar1 and @mesch are telling you. No need for a preamp with the Outlaw. Like rar1, I had the 2150 a number of years ago in a secondary system and it performed very well.
I cannot think of a comparable product that offers the level of functionality and performance that the RR does, at it’s asking price. Outlaw is a great outfit and worth supporting. The new 2160 looks to be another winner for them.
I have a Schiit Yggdrasil, so I am not biased against Schiit. If you see yourself going separates in the future, it would be the obvious choice between the two (if these are your only 2 choices). It would also be the choice if you believe you will go the mono route and need the power delivered by the monos. However, if you are working through those issues, the Vidar should be up against some other amp-only options.
Enjoy your new system and choices.
