I owned the M1's - Clayton's early and best platform for the M series. I then upgraded to the better horn and x-over. No matter what, I found bass always deficient and anemic while upper-frequency detail was just totally MIA. BUT, the mid-range, especially horns (I tend to listen to jazz downstairs), coupled with my room in an amazing and really satisfying fashion allowing me to keep the early M1's for several years. But now, owning the M3's THERE IS NO COMPARISON. The M3's are VASTLY superior. Upper-frequency detail is splendid with tight, tuneful, textured, pitch distinctive, and rich bass blooming into the room like no other speak I've owned. You would be well served to save for the newest version M3 as the older models are simply no longer representative of Clayton's work/ideas. Not even close. IMO, you're throwing out $$$ purchasing obsolete product. And, if you're not happy with the older product you might be inclined, falsely and unfairly, to discount Clayton's current products. That would be a tragedy because I don't think you'll find anything, near the M3's price capable of comparable performance. FWIW.
