Had an extensive listening, comparing my HeadTrip's sound vs Dave's headphone output:
The DAVE hang on good down to volume 11 = normal listening level, and then it get more stressed out on vol 7-5 , so when it comes to the more bass dynamic heavy parts in the song DAVE does break some svett, but on lower levels like vol 12-17 with the Abyss, it sounding so smooth with details appering that i dont even think the mastering producer have ever heard before. You also find the technical miss outs flaws, unwanted distortion in the song from the studio.
But i do find you need a separate amp if you want listen to more dynamic music , classical music with high DR on little higher than mid-high level .
You loose just a slight bit transparency but in the same time it sounds more muscular , where the voices and bass guitar are deeper.
Compared to Hugo , DAVE is more calm and smooth in the presentation so you can hear DAVE is more powerful than the Hugo, and it is a fairly big difference in btw!
So a separate amp if you own the Abyss or He-6 is my recommendation, but you would be happy with only the DAVE alone also!
And in the same time you have two different sound tones from the same DAC, so you can just pick and choose depending on the material and your own mood.
The deep fluid bass , perspective , timing , detail resolution spaciousness, musicallity , dept and 3D is mentally good, and are the leading key words that describes the sound of DAVE, or we can use one word:
Ultra Transparency .
With cross-feed filter set to on 1,2 or 3:
Here i find great reduction in resolution and spaciousness when you activate cross feed filtering, i do not like it so much, maybe with other headphones but not with the Abyss.
Just on some tracks i find it to be usefull, but most of the time i have it set to off.
Without cross-feed filtering i can easy pinpoint where diffrent instruments are located in the studio or in the concert hall, which is impossible with croos-feed when everything is placed in the center of the soundstage.
World best DAC at the moment, and i hope for a good time to come.
