Preamp for Mccormack 0.5 mono

I am using Proceed Pre with DNA 1. It's a great, very dynamic and transparent combination. Pre has HT bypass.

The Tube Audio Design TAD 150 (current model) sounds good on McCormack amps. Also many people feel an Audible Illusions tube preamp is a good match. I personally prefer solid state preamps with the McCormacks.

I've been looking at the TAD150 and even talked to Paul about it.Sounds like it would work well with theMccormacks,
but I think I'm leaning towards the RLD1.I like the idea to send it back to Steve and have it upgraded,plus the input impedance for the mono's are the same as the preamp at 10k.So I think it would make a pretty good match.
What do you think?

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.
