Well, since you mentioned
, I had a chance to hear
FAudio Mezzo LE right before CanJam SoCal, borrowed it for a few days from Andrew/MT. Here is what I have in my notes.
I found Mezzo LE to have a balanced soundstage sig with natural revealing tonality (with
all switches off). It is tuned to have a very spacious sound with a huge 3D soundstage expansion. The bass is deep and punchy, lower mids are neutral, more toward the leaner side, upper mids are quite organic and detailed, and treble is crisp yet still natural, non fatigue.
As one can see, it does have 3 switches to change lows, mids, and highs. The OG version I tried back in Feb during CanJam NYC was tuned a bit differently because I clearly remember needing to toggle switches to make it sound better. Here, what I found with Limited Edition model:
Sw1 - brings more energy to the treble, giving it a crisper bite with a higher res definition.
Sw2 - pushes mids more forward which attenuates the bass down, gives treble more air, and makes vocals brighter, colder, more analytical.
Sw3 - boosts the bass, elevating both sub-bass and mid-bass, it functions like a shelf filter which affects only the bass while still keeping mids natural and detailed, and treble crisp and clear. But the perception of mids changes under this tuning, pulling them slightly back.
Sw1+3 - tried two switches, this suppose to boost the bass and the treble, but it made mids more forward and treble a bit hot.
For me personally, in this Limited Edition (LE) model of Mezzo I enjoyed
all switches off. But you do get a choice, depending on your sound preference.
And for your FR junkies, here is combined graph with all switch variations. I know, some of these curves are too close and not easy to follow/distinguish, but you can get an overall idea.
