I have listened some to those ML 60XTs. I thought they were on par with similar offerings from Klipsch, etc. Mediocre, but not terrible, and this is coming from an admitted ML fan. I agree with others, if you are considering ML, you should look at the ESL hybrids. I have the Montis, and yes the super sweet spot is somewhat narrow, but I find that the sound imaging does not roll off much as you move off axis. Probably due to the dipole nature. IIRC, I sold my Ethos for a little less than $3K, so in the same ballpark.
