With construction quality of the amps being equal I agree the speakers can make huge differences. An old pro sound engineer in Austin was fond of saying there is no such thing as a perfect speaker. All we can do is pick the distortion character we can live with and go from there.

Certain speakers do have amplifier preferences. I have a fondness for vintage Polk Audio while others would not give the SDA line more than a passing glance. For the Polk's, high current design amplifiers are critical. (Much the same as the Maggies) I have the first generation Tympani in need of complete overhaul. Once repaired they will go up for sale as I have slowly lost interest in them.

Some companies do a great job with things like parts matching making for wonderfully balanced amplifiers while other companies do not seem to think it matters. From eveeything I have read the Outlaw products seem to have been constructed with great attention to detail.
