Will Squeezebox Touch play iTunes from USB Drive?

Yes but, depending on how big the library is, Touch's speed and convenience will be variable.

Are you saying there would be pauses during playback, or slow response with the SBT GUI? I assume wireless streaming or ethernet connection to iMac would work better then? The iTunes library is 155GB (Apple Lossless). I could run ethernet cable but I preferred the simplicity of a bus-powered mini-drive.

My experience is that it takes a long time to index the drive and that access time is slow. Also, it is not certain whether the Touch will power that drive.

Thanks. I had drop-out issues with SB3 in the past and was concerned about that recurring. I'll still try streaming, as well as the mobile/bus-powered drive since I have one. More then likely I'll have to run ethernet cable to iMac.

There's a lot more digital wireless and FW/USB sources now, but I don't have time to go through that again. I need something this week. If not, I'd look into the Weiss FW converter and others. I'd like to plug my iMac directly into my reimyo DAP-777 but not if it's going to cost thousands. I already put that into the DAC and other gear. And I had the iTransport/iPod server. Loved it, but wanted a larger GUI and didn't want to have to copy music over to it. It'd be great if you could use iTouch/iPhone/iPad in a dock and stream through that right into the DAC.
