Great examples of each but I will say I’ve never really liked any super efficient speakers. I heard some Cornwall 4 when I was buying a sub for a guy and they sounded great for the little bit I heard them but playing music I don’t listen to at not very loud volumes. LOVING my new B&W 801 Matrix. The voicing is just so freaking good for me. Again pigs to drive.
We should reject hard-to-drive speakers more often
Sorry I know this is a bit of a rant, but come on people!!
Too many audiophiles find speakers which are hard to drive and... stick with them!
We need to reject hard-to-drive speakers as being Hi-Fi. Too many of us want our speakers to be as demanding as we are with a glass of wine. "Oh, this speaker sounds great with any amplifier, but this one needs amps that weigh more than my car, so these speakers MUST sound better..."
Speakers which may be discerning of amplifier current delivery are not necessarily any good at all at playing actual music.
That is all.
