I disagree with that.
I think speakers with exotic, exquisite, or ultra-fine cabinets don't come cheap.
I think speakers with ultra-accurate drivers and precision crossovers don't come cheap.
Cost may translate into beautiful and ultra-crafted cabinets and parts.
But cost does not always translate into SOUND QUALITY to EVERYONE.
The same could be said with speaker measurements.
Some speakers may have extremely little resonance due to their extremely well-made cabinets, but yet may not sound that great to everyone.
Some speakers may have excellent frequency responses, but yet may not sound that great to everyone.
When you audition enough speakers, you will probably experience that.
No matter how many times I listen to the Infinity P362, I'm amazed at how good they sound to me. Sure, some people don't think they sound good, but a lot of people would agree with me that they do sound great.
I dare go on record and say that I think the P362s sound better than some speakers costing 5 - 6 times.
Sure, you may think I'm crazy.
You may disagree 100%, but please don't get offended.
That is just my honest objective opinion.
On the other hand, I've auditioned the expensive Revel Salon 2 towers and the KEF 201/2 bookshelf speakers, and I think they are worth every dime.
Cost can translate into sound quality. Sure it can. But not always.
The ONLY way is to actually listen for yourself.
But there are other factors to buying speakers. Like the speakers themselves, the determining factors are also made of compromises.
Do you want speakers with a high level of "respect" or "pedigree" or "pride" or "prestige" or reputation?
Do you want speakers that look beautiful aesthetically?
