Yeah...that's exactly what I discovered with the M3s. And as you know, I wasn't an M3 fan. However when you set M3s and M5s side-by-side, there is a big difference in everything. The limiting factor in your system now is the electronics - and I'm not talking about power but rather finesse that only great quality electronic design can dish up. I just found that out last night.
