I've been very happy with my ADAs (1500-4 powering the LFR-1100s, 1000-4 powering my 4 surround channels). They may be overkill for my space, but that's what I was going for. I never wanted to worry about power, and I haven't. After I upgrade to a full-fledged Atmos receiver, I'd like to get another to power the remaining channels, but we'll see what my budget is at that point. I wouldn't hesitate to recommend them.
