My first music server was the iPod Classic and Wadia 171 iTransport. I still use it for work, along with a Benchmark DAC, and headphones.
Anyway, today I am adding more files to the drive I use with my BDP1, and then copying that drive onto a new drive I just bought for my new BDP1 I just received for the HT system. While that takes place I am music less unless I use the SACD player. However, it occurred to me to see what happens if I attach the iPod to the BDP1. It works! The directory names are screwy due to how Apple stores files, but all the music is there. So now I am playing tunes through the BDP1 with the iPod as a source.
Life is good. At least sometimes.
