Hi Anwar, I followed your advice. It plays beautifully from my 32GB memory stick. But I have plenty of other old music (80GB) which are from my mp3 collections which I will never really be able to get on my CD. I occasionally listen to this, though the sonics are not really of the standard that the SA-10 deserves. But still old music has its own charm. So I purchased a 128GB memory stick, which I had to use a different formatter to format as FAT32. Once this was done, I copied around 700 folders with less than a dozen files in every folder. I stuffed it into the SA-10 and it played everything flawlessly, and taking no more than 30 seconds to read the stick. But when later it went into standby and i restarted it, it would almost get frozen in "loading" mode and i became a bit worried. So I pulled the pen drive out and reformatted it, and again loaded the files, this time fewer files. The same thing happened. Initially loading took 30 seconds, I played a full day of music, and next morning when I restarted it, the SA-10 took more than 5min before i once more became worried and switched to a different input. Now I dont use PC audio anymore, after getting the SA-10 and cant live without my old MP3 music either. So regular CDs and SACDs apart, how does one carry on with the 80GB of old mp3 music? thanks a ton for looking.
