The literature says that the MM-500s are "5 yrs" in the making.... so, that is the same as the LCD-5, or is it before?
Unclear....
I personally hope it does not sound like the LCD-5, as if it does, then that means the bass is going to be small, the sound stage is going to be its weak link, and it will have an annoyingly forward midrange that Abyss will love.
It would have been nice had Audeze selected a "famous" producer-mixer-engineer, who stated that he has had years of experience with headphones, especially regarding listening to them..
So, this is a case of a person, who is not a Headphone audiophile, being chosen as a Marketing situation, first and foremost, who is use to Studio Monitors.
This means that he no serious experience (years) with Highend Audiophile Headphones, and his game plan was to create something that HE can use, to mix and master, that is shaped like a set of Headphones. He casually states that you can uses the MM-500 for deep night listening, yet, he's not familiar with this at all....so, that is just a tag line, meaningless.
It will be interesting to hear the MM-500 as an Audiophile product, as its really designed to be a set of studio monitors for your ears. And for this to work, they have to be very neutral, very linear, and very, well, flat. As any other type of sound performance, isn't a true studio headphone, as this one is designated to SOUND.
I suspect its going to sound more like the MX-4, then the LCD-X, as the MX-4, is trying to be the studio monitor professional sound.
Here is what we know.
We know that the first 20 people that buy them, will run in here and declare them to be the "ultimate", "astounding", and then they'll all sell them in about 3-6 weeks.
Looking forward to it all.
