Lee, as far as someone "coming forward" to offer an audition, although that does happen on occasion when the request is seen, generally the burden is on you to make contact by way of a PM to someone in the area, as shown in the audition thread list.
My music listening also is almost entirely classical and I can assure you that the M22s supported by a good sub(EP500 in my case)do a superb job, including pipe organ recordings. I haven't heard the M60s, but there would appear to be no reason in theory why they would have a "fuller midrange"(whatever that means). The M22s use two 5 1/4" drivers to cover that while the M60s use one 5 1/4". Frequency response graphs indicate that both are substantially flat there and are neither "full" nor depressed.
