Well, yesterday afternoon, I drove over to Wadia's HQ and picked up one of the few working iTransport pre-production units to borrow for a few days. (I believe
Tone Audio is also getting one to play with for a bit, so I'll be watching
Tone Audio for an iTransport review at some point in the near future.)
The first thing I did when I got to my main rig was to hook the iTransport's S/PDIF output up to an
MSB Gold Link III / PowerBase DAC setup with a
CablePro Tracer v.2 Digital Coaxial Cable. The MSB DAC is currently feeding a
Ray Samuels Audio Raptor, which I use to drive my
Sennheiser HD650 and
Grado GS-1000.
From an
iPod Classic 160GB (firmware v1.0.3), I played files encoded using 320 AAC, Apple Lossless and straight WAV, using the MSB to upsample to 24/132.3. The results (especially with Apple Lossless and WAV, but even with 320 AAC to a lesser degree) were awesome.
Awesome. Bypassing the iPod's DAC completely (and using a good outboard DAC instead) completely changes what the iPod is, turning it into a nice transport and media server. In short, the iPod becomes main-rig-worthy as a transport, if you've got a good outboard DAC.
As for video: One of my out-of-state co-workers is staying at my house for a work visit, and we watched
Hitchhiker's Guide to the Galaxy (purchased from iTunes), using the iTransport's component video outputs and analog audio pass-through outputs, hooked up to a 57" HDTV. Using the TV's so-so up-converter, we were able to get a pretty good picture.
I see the video output as bonus. As a Head-Fi'er, it's the audio quality that one can get with a good DAC, using the iTransport's bit-perfect S/PDIF output (thus bypassing the iPod's internal DAC completely), that excites me the most.
I'll say more about the iTransport later. This is, in my opinion, a very important piece of gear.
