Got them.
Have listened to them.
1.) Comfort :
8.0.
Strap does not disappear and could use more padding.
As a matter of fact, the strap is not as comfy as it appears it would be, and you constantly feel it on the top of your head.
It does not disappear once you start listening.
Fit is comfortable and does not clamp or squeeze.
The angled pads are more comfy and offer (obviously) a better seal.
Headphone are not as heavy as Audeze, and not as light as Sennheiser H6's.
2.) Sound:
Pristine, smooth, detailed, refined.
Sounds good right out of the box.
I dont find them "midrange forward" or "low mid bloated"..., i find them really well balanced, overall.
Is their treble response (right out of the box) going to play better with Tubes?
Yes.
3.) Soundstage :
Wide.
Its actually wider with the cloth pads, and narrows a bit with the Leather, but, ither way, wide soundstage.
4.) Presentation of instrument within the stereo field :
Excellent.
Very much a "speaker like" presentation that lets you "sit inside" the music.
You will hear things in your music collection that you have not noticed before.
This is a vocal lover's headphone that plays well with acoustic instruments.
5.) Freq Response :
Treble : Sparkling and pristine. Quite extended.
Mids : smooth, detailed, balanced.
Bass : Ample without being overcooked. Detailed. Good extension but definitely not a bass lover's dream.
What doe they sound like?
Tonally....= I think they sound a bit like Aeon Flow Closed, yet with more lush mids, more resolution, wider soundstage, and a better (bigger) bass response.
As compared to Audeze (in general and not including the Sine or EL8 series) ......: The Quads are not as dark sounding or as thick sounding in the lower register and the mids are more precise.
There is nothing (sound wise or build wise) about the Quad to dislike. It sounds very good, it wears without discomfort, and its an attractive set of headphone(s) tho its not a beautiful set of headphones.
Box and Case are Utilitarian blase and do not represent the quality of this product's sound.
The only thing i have noticed that could be an issue, is a slight "pinging" in my right headphone, a metallic "ping" sound as if something is clicking against the cup.
I'll investigate further...... and if its an issue, i'll return for another set.
