Maggie LRS vs .7

I had a pretty easy time with placement or my LRS and LRS+ but could never quite get it right for the Maggie Mini's ...

Bigger is better.

The first high end system that blew me away was fronted by Magnepan speakers, MMG's maybe, with a Hafler amp and preamp.  I have considered them many times, but I have a long narrow room with the speakers on the long way and only have about 3' of space behind the speakers.  Is that a deal breaker?

I had both. Started with the LRS and then moved to the .7s. I thought they were similar but .7s go a bit lower.  I had a bigger space they were in so the .7s were more appropriate. Ultimately, I went open baffle to get the transparency of the Maggies plus dynamics that the Maggies lacked. 

As to the OP, I think the decision to upgrade depends a lot on the size of your listening space. 

I have the LRS+ (AGD Tempo amp, KEF KC92 sub, MagnaRiser stands) in a 25 x 25 x 8 room and it is simply superb. Definitely use very heavy gauge speaker wires.  I have large diffusers 4 feet behind each speaker. Side reflections are not an issue with Maggie’s. I recently ordered a pair of Orchard Audio LPS mono-blocks (500>4ohms) to see what if anything they bring to the party. This sub integrates beautifully with the Maggie’s. All FYI, hope it helps.
