You're right...phase and impedance isn't enough data. Tube amps don't like (can't remember) either capacitive or inductive loads......But to read most posts about speakers, all it takes to be a bad load is low impedance and lower 'efficiency'.....most don't even call it sensitivity, the correct term. Speaker tuning and alignment help determine the sweet spot in damping factor for example. I'm not even going into more advanced measures.....waterfall, impulse response and others.....Hearing is believing.
Also, amps vary in their ability to drive such reactive loads....even SS stuff. I'd LOVE to see a HT receivers reaction to the power cube test I linked earlier. Take a single line and test from bottom middle than top. Best of luck.
The reason I'm down on HT receivers are many. Only OK amps. Limits to speaker selection. Planned obsolescense. Marginal to Poor resale market. Fewer and fewer places to get one over 4 or 5 years repaired. I measure value over years. Before an upgrade cycle about 4 or 5 years ago it had been 20+ years since the last. My old speakers were late 70s and my tuner/preamp was mid 80s. My speakers received a Factory Rebuild in about '05. Try THAT with almost any other speaker but Magnepan. My carryover component is an OPPO upsampler
I think my system is listed here.....on AA.
Above a certain price point, a prepro / external amp makes more sense. The Marantz pre/pro looks awesome, for example. If I were a HT guy, something along those lines and a decent amp(s) would be the obvious way to go. At lower price points....I'd try to go for a HT receiver with pre-outs. The 'saving' of the receivers PS should pay downstream dividends while allowing less expensive upgrades when the next round of 'new' hits.....sometime next month.
The last time I looked at HT receivers I noted how HOT they ran. If I stuck one in my current setup, I'd cook it in a couple months, no matter what speakers I was running. I'd have to go open rack for sure.
BTW, some speakers don't exactly measure easily. Open Baffle / Panels / Electrostats all have certain physics limits. Stereophile does good work...and maybe that site you suggested earlier. Cabinet resonance as measured by stereophile can, as you suggest, but used to eliminate some 'boxy' sounding speakers.
Some reviews are ending up as a listing of features and connections, rather than exhaustive listening.
I'll stick with less is more. I don't see how, for a given budget, you could possibly equal a good 2ch system with the same $ value of multichannel.
Even though I DO watch a lot of video, my system is clearly biased to music reproduction.
Too much is never enough
