Hi Yuki, I know you have a ps3 and Im not sure if this happens to your ps3 as well. When playing music off a slow 2.5" external hard drive on my ps3 while using 176.4kHz as the sampling rate. Songs kinda stop for half a second then play again through out the songs that I play. I'm not sure why it happens and its kinda weird. CD's and music from the internal hard drive is fine otherwise.
also what type of bitmapping are you using on your ps3?? type 1,2 or 3?
PPS: Do you notice any sound improvement when playing music on your ps3 using the 176.4khZ sampling rate because I think It sounds better
