Great Review! You (and many others) are helping me realize the X5 may be the way to go as I move, SQ-wise, away/up from my iPhone 5s and iPod Classic. I like your assertion that this may be all the money you need to spend for better SQ, not the $999 and up we are starting to see! If I could ask a question: what is your existing music library encoded in? My entire library is CD's encoded into Apple Lossless through iTunes, hoping that I can easily transfer and use all those tunes on an X5...thanks for any info.
