The Maggies do need a boatload - I am using a pair of $3000 PS Audio M700 mono amps, rated at 350/700 WPC into 8/4 ohms.

I will be trying them with an Akitika GR-102 amp pair, running parallel, in the next few weeks - a pair of those amps is around $1000.

You make a solid point - the M5HP and an ADA-1000-2 would make for a pretty close total price to the LRS plus suitable amp.
