This post from DonH50 was very helpful in my setup. Try it to see how it can help you make your decisions on how you would like to proceed with your LRS setup requirements
per DonH50 Post
torii as an example, here's my results using DonH50s link:
Freq. Resp: 50-20kHz
Sensitivity: 86dB/500Hz/2.83v (1 Watt)
Impedance: 4 Ohm
Emotiva BasX A-300 Amp
300w/Ch at 4 ohms
Puts out 108.5 dB SPL at nearfield MLP 8.5feet from LRSs.
Being "hearing challenged" using Sound Level Meter,I set my PreAmp Volume at 85dB Peak before listening.
My music listening space is shared with Home Theater 4K Movie Viewing for Dolby Atmos 7.2, using Klipsch LCR FHL FHR SBL SBR and 2 subwoofers. (Action Movies can get pretty loud.)
I have some retro stereo gear dating back to the 70s. But the Magnepan's are a whole 'nother "ball-game". My first entry into the world of "High-End" stereo.
I discovered the LRS loved 4 ohms and high current. So I googled and found a review by Steve Guttenberg on Emotiva "budget" Amp BasX A300. Matched that with Emotiva PreAmp PT-100 and that put me in basement entry level of "High-End" listening.
Point is...I learned (a lot) from avsforum members, that the Maggies need their own dedicated Stereo system and lots of tweaking to show their stuff. As a final note, Stereophile review states..."When I set them up in my little 10' by 13' by 9' (130 square foot) room, they sounded dramatically more relaxed and fleshed out tonewise. It was immediately clear: the LRS prefers small rooms."
Good Luck (and good listening) on your quest torii.
