I've only read the very good reviews on all the recent new smaller Magnepan models but wanted to mention that any pair combined with a 4-sub distributed bass array system, like the Audio Kinesis Swarm or Debra dba systems for $2500, would result in hi-end performance at a bargain total price.
I believe even 1-2 good quality subs combined with a pair of these smaller Magnepans would offer very good full-range performance but I'm fairly certain a 4-sub AK or custom dba combined with a pair would provide excellent full-range performance.
I know 4-sub dbas combined with Magnepans work extremely well together because I use an AK Debra 4-sub dba with a pair of the older and larger 2.7QR Magnepans in my combo 2-ch music and ht system.
All Magnepans seem to have excellent mid-range, treble and imaging qualities but tend to lack deep bass detail, power, dynamics and impact. The proven 4-sub dba system concept provides these missing bass qualities and does so seamlessly with virtually any pair of speakers, but especially well with fast planar-dynamic and electrostatic panel types.
I'm seriously considering trying a pair of these smaller panels in my system since, although my larger 2.7QRs still sound great, they are now over 30 yrs old and I'm very curious if this would be an upgrade in my system performance.
