Just got a new ES300 with Mark Levinson. After 3 weeks of listening to it, here are my thoughts:
The overall sound is smooth and powerful, but is lacking something. I think the sound system is filtering out too much of the high end. It doesn't really have that bite that it should.
The Eq. that's included on the Nav System screen is a joke. You're only given control over three components of the sound: Bass, Treble, and Mid. I figured for this kind of money, they would give you a full Eq., with some kind of realtime feedback, like the Eq. in WinAmp works.
As far as speaker placement goes, I'm mostly satisfied. However, there's one troublesome speaker in the car....on the driver's side, about seat level. When I drive, my left leg seems to get in the way of this speaker. It definitely blocks the sound. If I extend my leg (under the dashboard) it gets out of the way enough to let the speaker work correctly.
All in all, I would have to say that the Levinson system is not at all worth the money. The stock stereo sounds just as good to me....almost better, since it's a lot less expensive. Save your bucks and use the money to upgrade later.
