The 10T's have been well received for years. They won Stereophile's Speaker of the Year award in 1996. They thrive on power and the more the merrier. They are capable of phenominal bass in the right configuration.
Several years ago, it appeared that many 10T owners were using krell amps to power them. But then again, I've never met a krell owner yet that I liked. :)
I would venture a guess that the sound you would get from this krell mated with the 10T's would be somewhat rounded and on the warm (rich?) side of life with at least a little bass punch thrown in.
For the price you're talking about, there probably is not a better overall speaker.
Due to crossover changes, I would recommend staying with the newer versions. Those that were built 1997 and later.
