I had Ohm Walsh 4 with upgraded drivers, still over 15 years old on the upgrade. The super tweeter went out and I started looking for something new and...different. I auditioned and bought Emotiva T2s and really liked them, at first, but was breaking in the Spatials at the same time. The M3 sounded....not so good at first, but I kept playing them loud when we left the house. (Bella Sonos, Carboot Soul, Massive Attack)
After awhile(75hrs) the M3 really started to open up and provide the "air" that I like. The bottom end was very nice too but I wanted some more, uh, body. So after some research I settled on the Rythmic L22.
I use a Sonos connect and optical into the Nova300. The rest of the house has Sonos 1, 3s, 5s, playbar and sub, and Audioengine 5 scattered around. All sound good, but I really enjoy the M3/L22 combo.
I have listened to some classical and find them to be...revealing.
