This is right. I have Westone 4R & UM3RC and with the ipod touch alone they are lacking. Music sounds far off and dull. Fostex bypasses touch 5G dac and plays it through its dac / amp section through USB. The filters at the back of hp-p1 does magic to the sound.. It was this or the Hi-FiM8. Since Fostex has optical in, I chose it. It works with one of my discmans (d-ne10) but not the other ones I own (I am a discman addict still). Not sure why it is.
Initially hp-p1 was purchased for ipod touch 4S, but I sold it recently and didnt have the need to keep 2 ipods. Also watching movies and listening through the hp-p1 sound much better.
I do need to get a smaller cable as I'm using the ipod touch 1m cable, I dont move around this set up too much and its mostly stationary for now.
