I'd be inclined to go for a C46. Great synergy with the Mc402 and no tubes to worry about. The C46 had a warmish/musical tonal balance in combination with 402. It is a combo one can easily enjoy for many years and not feel the need to upgrade anything. Of course we all have our preference but the McIntosh solid state preamps tend to sound like tubes anyways. The tubed preamps, well, you'll be tube rolling and spending dough on tubes in no time.
