Wondering what your opinion is on sound quality between those 3 amp/dacs, and what headphones you have them paired with?
Cheers
I have to write a review on a french forum, but it is not for now. I will do it by the end of the year. I will let you know when it is done.
There is a question I can answer though : I mostly listen them with my signature pro, especially the ADL X1 because this one is really made for on the go sessions.
I paired the others with Q701 and DX700, but only the Theorem is very good with the Q.
The fostex provides a very good first impression, but the sound is really not neutral, imo. Rather something clear with great basses, but it plays music in a different way.
Adl X1 is quite neutral, with a bump of warmth in the lows, the perfect match for a mobile use. It is the pocket size one. The others are bigger and heavier.
Theorem 720 is very good and the more I listen to it, the more I love it. At first I was disappointed, but it is a good performer from low end to high end. The highs are not smooth as they are with fostex hp-p1 but it seems to me they sound more like they have to do. Its great weakness is the hiss. The volume is quite high even at the minimum for those who like to listen music at very low volume.
There is a little hiss (but far less) on the X1 too.
I also have the pandora hope VI. No issue with the hiss on Adl X1 and Fostex HP-P1. A pain on the Theorem.
Sorry for my poor english. I lack vocabulary and I read it better than I write it.
