I have Edition XS for a while now. While I didn’t have the chance to use them on my desktop chain much, I definitely like them. The guy I bought if from said I’d probably get rid of Sundaras once I heard XS, but I doubt it. I am absolutely in the same camp with @Resolve about these who also convinced me to buy Sundara in the first place.
Edition XS is good. I have a few kilobuck pairs and they still wowed me in the first listen, which didn’t happen for quite a while. However after a while I also noticed their short comings. First I miss bass impact on these. Transducers are capable of producing tight quality bass. It is linear and for the songs that require linearity it is exquisite. But I couldn’t make them punch in EDM songs etc. Did I say one of the forementioned pairs is Clear MG. So take that as you will, maybe I am spoiled.
Also like @Resolve mentioned, I couldn’t completely appreciate that “U” shape in some songs, vocals went a little too far back for my liking when instruments are also in the picture. I missed Sundaras in those songs.
Lastly again I also a little annoyed by the zingy nature of the upper treble like Andrew. But I have to remind you these are rather small gripes. I don’t expect XS to do everything perfect, it can’t be both V-shaped, neutral or mid-forward, right? I have different pairs just But the soundstage is one of the widest stages I heard so far. I would suggest Edition XS especially to those who want to experience wide soundstage on a budget.
