Paul29, I think the RLD1 is an excellent choice for your monos (your very fortunate to own them), eliminating the possibility they would not have any synergy together, plus it comes with a remote. I have enjoyed over the years using the McCormack amps (especially the ones with revisions) which represent an excellent value & investment in sound quality, his preamps are no exception! I also agree that having the option to upgrade when you can afford it, is the icing on the cake.
