MikeM,
To lessen your agonizing, here's something to consider: As a veteran of many years of double-blind speaker comparisons for A/V magazines I edited and wrote for, occasionally there would be two speakers within a group that were so close in sound quality and numerical rankings, that I would often write down on our rating sheets, "similarly good."
Sometimes, slight preferences emerged depending on which musical selection we listened to, but in the end, the similarly good speakers would garner scores separated by as little as one-tenth of a point. This was not a statistically significant difference.
I have not A/B'd the Monitor Audio Silvers (I heard them in a demo) with our best Axioms but Monitor Audio has built some very nice speakers over the last 5 years, although at quite a premium in price. (In contrast, early MA speakers a decade ago were pretty awful.)
Regards,
