Depends on your musical tastes. The Lintons are more mellow than the others, more of a vintage tube-oriented sound with restricted power-handling. If they were Super Lintons, which have the purple fried-egg tweeter, they would be my choice. I still have the tweeters from my pair.
The KEF C45 has an okay sound, but the KEF C series were the more moderately-priced KEF line, with the possible exceptions of the C80 and C55. I think the Tannoys would have the nicest mids and highs of any of them. There is nothing wrong with the Mission 701's, but they don't quite measure up the 632's, in my opinion at least.
