Try not to get too wrapped up in the hour-by-hour impressions you get here of various headphones, particularly TOTL cans like the LCD-X. Just listen to your music, watch YouTube vids etc and accept that some days will be better than others - that's life, even with nothing more than an iPod and a $10 pair of Philips IEMs. It's fascinating that some Head-Fiers seem to regard their brains as somehow static participants in the whole process - no different to the cable between their DAC and headamp - that just isnt the case, IME. If it was, I could happily listen to virtuoso musicians that bore me witless 24/7 - regardless of the gear, that starts to sound like elevator music if I listen to it long enough
The best thing you can bring to this hobby is a good night's sleep and a really good recording of the music you love and cherish.
