Are these "high end speakers" in this analogy high end flat studio monitors or high end HiFi speakers?
Because high end HiFi speakers don´t sound like real life, but high end flat studio monitors do.
I own and have listened to many high end flat studio monitors and LCD-2/3 doesn´t sound anything like flat studio monitors. They sound muffled and scooped from the upper mids like I´ve said. That doesn´t mean that the flat studio monitors sound ear piercing in the upper mids, they just sound "real", unlike the LCD-2/3, which sound "not real" to me, but sound good still. Sometimes, actually quite often "not real" sounds better than "real". People have their own preferences and it´s subjective. Some like "not real" sound more, some like "real" sound more.
For instance, the high-end Audio technicas (i.e., Raffinato; ATH3000Anv) do not sound real to me, but I still love (particularly the ATH3000) the way they sound. They sound euphonious (i.e., easy on the ears; seductive), but not "real" per se.
