I will admit I'm quite a fan of panels, and I'm quite a Magnapan fan. I have their 0.7 as my "surround" speaker and their wall mounted MMC2 as my rear speakers, and they are brilliant in those roles paired with my ML front and center speakers, and subwoofers.
My initial plan was to migrate to Maggies, but frankly that was thrown out when I revived my oooooold Aerius speakers with new panels as an interim solution, then didn't like Magnepan's CC5 center speaker I had acquired, so I replaced it with a 34A just before the *last* price increase. Much to the dismay of my bank account, the 34A decision only happened after I had committed to two BF210s before *their* prices increased.
I love RJ's posts, but I have to disagree with him slightly. Magnepan may not be at the level of the speakers he noted, but they're truly exceptional and in many ways an enormous value. The 20.7s, in particular, are about $10k less than the 15As and may outperform them in certain ways, while the 15As in turn outperform certain aspects of the 20.7s (and in my opinion, have better aesthetics for my room.)
In any case, it's been a really fun path I've traversed and I wouldn't change it if I could. I wouldn't have gone to this effort and expense, but I did it for my brother who had been working from home - my home - due to Covid, and he really loved all the improvements I made for both audio and video in the system. Unfortunately he succumbed last month to sepsis while being treated for leukemia, but I get to enjoy the fruits of that audio/video effort for years to come.
The 15As are going to be fun, both for two-channel and home theater use. I still have some other tweaks to add, but the system today, pre-15A, is incredibly resolving and draws me into listening to old favorites and newly discovered music (thanks Roon!) for hours on end. I want to add many thanks to
@ttocs on this too, as his assistance with Dirac and subwoofers has been pivotal for the home theater configuration. (I bypass Dirac for two-channel playback.) My brother, Pete, was amazed by the results. I kinda cheated, doing a number of power cable and interconnect upgrades that really woke everything up. He noticed every time I'd make a change, but didn't know what changed to achieve those results. I still have a few cable and power upgrades to do, but they'll wait until I've worked the 15As into the system and broken them in.
Apologies in advance for all my rambling!
