Well, like I've been saying (as well as others here), it's happening whether there's a debate here or not. Simple passive acoustics, room correction (DSP), low mass amps and entry level speakers, inexpensive enough to make the audio cheapskate blush, are making their way into the audiophile mainstream way of thinking.
None of this needs Agon membership approval. It's just a fact that simpler, happier audiophile days are here that is far more practical then what was preached years past.
Many of you are putting together, past and now, systems that rival the big buck systems and that's good. The cool thing that I'm talking about is, your sharing your findings and that's what is needed. And, that's what's going to balance out this hobby and introduce new blood to the magic of in-room listening. Headphone and car listening are already there, more or less, but HEA has struggled to get to that comfort level it deserves.
Room correction is now the norm, passive and electronic, that's a big step. Low mass is taking place, that's the most needed next step taking place. Low mass more gain.
