I personally wouldn't try to have Meniscus Audio reinvent the wheel. (Though that's what keeps high-end business flowing.) Just because they sell parts, refoam old drivers, and have a PC with Spectrum Analysis software doesn't mean they know anything more than rudimentary crossover design. The great speaker designers spend hundreds of hours tweaking and testing and re-tweaking to match a crossover with it's components and the cabinet. Have they asked if you prefer 1st order or 4th order crossovers, and why?
If edginess bothers you, avoid the Gallo's. They're the latest "hot stuff", but they are definitely for people who want it very live in the upper end. Of the 3 you mentioned, the Thiels sound about right. Or consider the Vandersteen 3a Signatures. Both Thiels and Vandersteens are available very reasonable used, too. Used Alons are another good alternative.
