@MikeyFresh, interesting comparison on SQ between the SDXC and msata. Although, I haven't done any direct comparison between those two (as I don't use the SDXC anymore), I agree the msata's sound pretty good to my ears. As I mentioned before in this thread, I did hear difference in SQ between the sdxc and CF when I was switching cards on one of my diymods. The SDXC sounded just less dynamic to my ears.
And we heard essentially the same thing in terms of the dynamics, the SDXC just seems a bit less lively, the mSATA (or CF in your case) punchier sounding without being aggressive or tonally objectionable. I also thought the bass was better in both quantity and quality, and thats kind of what gave it a grounded organic earthiness that I feel sounds more natural.
And before lots of people start to chime in and essentially argue/dispute, or otherwise feel badly about this, I'd like to again stress that these are not earth shaking differences, i.e. it's not a case of one sucks and the other is fantastic. You might also get a different result depending on which headphone you use, or depending on the headphone's sonic signature and your own personal subjective taste.
I value @DMinor's experience in that he can add to my original thoughts, but from the context of the DIYmod. My comparison used two stock Gen. 5.5 units in terms of the analog output section, both the line out and headphone amp are original.
If anyone has built an SDXC unit, you need not go into remorse, nor mount a verbal counter attack in defense mechanism mode, no big mistakes have been made. The SDXC is a great option particularly cost-wise in the 128 or 256GB capacity if you have access to the PNY card like we do in the States.
