I have had the SXC for just over a week and have burned the cable in with over 100 hours non-stop music playing before I had a critical listen. To my ears, the soundstage is very similar in size as the stock cable. SXC adds "meat" to the bones so to speak when compared to the stock cable. The stock cable is very good as it is but the SXC gives it more bass (not overpowering the rest of the mid or treble frequencies) and the sound is "fuller" and more musical experience, With the SXC, the experience is closer to my HD800 but the soundstage of the HD800 is still wider and the best - HD800 is also alot deeper with voices further back than the Andromeda. I did say earlier that I ditched the iEMatch with the SXC but I now use it again as I like it better with the iEMatch - even though hiss is reduced with the SXC, I can still hear it and it is annoying to my ears. Is the SXC better than a DAP upgrade, I can't say. It depends on a lot of things, like is the DAC chip and headphone amp on the new DAP better than the old DAP DAC and headphone amp etc. I use the SXC with Andromeda with my iphone 8 Plus and the Dragonfly Red and the iEMatch and it sounds very much a premium hi-fi IEM experience. The only downside is the SXC is a thick cable (and stiff) and quite microphonic to movement noises - so if you can ignore the downside, it is a very good cable that enhances the Andromeda sound signature.
