Mono recordings - Listen with one speaker or two??

I have been listening to the mono Beatles recordings using the two speakers of my 2 channel system and they sound great. But today I was daydreaming and wondered whether the mono recordings might sound even better using only a single speaker, since that is how they must have mixed/mastered back in the day. Does listening through two speakers somehow diminish the true mono experience? I have not tried it yet, but I intend to. Anyone already done it or have an opinion?
