Is the iPod, at long last, a high-end audio component?

(Credit: Steve Guttenberg)I never thought I'd say this, but I'm starting to think the iPod is a true high-end audio component. What's changed? I heard it in my high-end system, docked into Wadia's 170i Transport ($379). I can now testify to the iPod's bona fides.
Thing is, an iPod, even one loaded with uncompressed AIFF or WAV files, isn't all by itself a high-end component, but teamed with Wadia's 170i Transport, aka, dock, an iPod is elevated to high-end status. The transformation takes place when the Wadia transmits the iPod's zeros and ones to an outboard digital-to-analog (D/A) converter in your A/V receiver, or even better, a standalone high-end D/A. Wadia's claims that the 170i is the first and only "dock" to extract a digital output from an unmodified iPod.
The 170i's digital out sends a 16 bit/44.1 kHz PCM digital signal to a D/A. The 170i does that for MP3, AAC, Apple Lossless, AIFF, and WAV files, but just be aware that it converts all but AIFF and WAV to 16/44.1. It can also pass 16/48 PCM, but in most cases 16/44.1 is what you'll get.
According to Wadia's national sales manager, Martin Cooper, iPods store MP3, Apple Lossless, and AAC files in Apple's own digital language, and when an iPod is nestled into a 170i it converts those files to 16/44.1 PCM. That way, the signals can be processed by the D/A in your A/V receiver or high-end D/A. MP3, Apple Lossless, and AAC files will sound "good," just not quite the same as the original CD. In other words, only AIFF and WAV files can be heard with bit-for-bit accuracy over the 170i.

The digital and analog audio outputs, plus component and s-video outputs.

For these listening tests I hooked up the 170i Transport to my high-end system: Sunfire Theater Grand III surround processor, Parasound JC-1 power amplifiers, and Magnepan 3.6/R speakers.
The iPod Nano 4GB/170i's sound was highly resolved, with great depth and high frequency air. As a "control" I hooked up the Nano via its 40-pin connector to the system. I can't say the difference between the Wadia docked iPod and solo iPod was huge, but significant enough to sway audiophiles. The Wadia docked iPod was cleaner and more transparent.
Awful sounding CDs, like Bruce Springsteen's Born To Run, still sound awful--whether it's a CD, AIFF, WAV, or 128 MP3. The old "garbage in, garbage out" truism hasn't changed.
The Wadia 170i Transport will delight audiophiles--you know, people who really care about sound quality. And yes, it'll pass video over its S-Video and component connections.
Have you heard the 170i for yourself? Are you planning on buying one?

When playing 70's rock it is ACC DCC but that is a very bad pun.
That said, for about same money you can get a real computer with an optical output on its sound card, hook its video to your TV, hook the optical audio cable to your receiver, and enjoy. Or just get an universal (DVD+flash+iPOD cradle) player with optical output. Will cost about the same AND play DVDs.
BTW, I loved you in Short Circuit, which the animators of WALL-E have totally ripped off.
Presumably you listening to this in your home where you have all your expensive audio gear. And if you have an iPod you also have a computer with the capacity for Terabytes hard drive space. Why not put all your lossless audio there get digital out into your gear and then control it with an iPod Touch via wifi from anywhere in the house?
...Apple Lossless, and AAC files will sound "good," just not quite the same as the original CD. In other words, only AIFF and WAV files can be heard with bit-for-bit accuracy over the 170i.
The whole point of a Lossless codec is that it is bit for bit identical to the original when played back (hence the Lossless moniker). Am I missing something, or is my understanding of how the Lossless codecs work wrong?
First of all as most of you know, the iPod is a portable jukebox. You can use it as a personal player to play back your 128KB AAC files through the ear buds that came with the iPod, or you can bump the resolution up to 256KB AAC for better audio playback, as well as upgrade to more expensive ear buds... Not everyone listens to the iPod with just ear buds! I don't...
Then there is AIFF, WAV, and Apple Lossless which are much larger files of the same songs, but bit for bit accurate to the original "Red Book" CD's. Yes more music fits on the iPod with the AAC encoded files compared to the lossless ones I've just mentioned, so some sacrifices need to be made. My music is all in AIFF format on my computer as well as the "Playlists" I've created for my 30GB iPod. Once you have AIFF formats, you can always down convert to AAC if drive space is at a premium. Up converting from AAC to AIFF does not improve the sound quality it just makes it 10 times bigger than the AAC with the same AAC sound quality. In other words, you can't make a lossy file like AAC or MP3 sound better once you chopped off a bunch of the data bits, while you can go the other way, AIFF to MP3 or AAC anytime.
Yes I can use my Airport extreme and stream Airtunes to my stereo equipment from my Mac, but I don't like the fact that I am taxing my Hard drive with excessive use and hours all the while I'm streaming my tunes. I listen to music for hours on end every Friday, Saturday and Sundays... 20 Hours plus on average every weekend adds up, and sooner or later my drive will crap out sooner than it should under normal use! To me, not a wise move...
This is where the beauty of the Wadia comes in. It is a "Pass-Through" device, meaning that it takes whatever songs you have on your iPod, weather encoded in AAC, AIFF, WAV etc. and bypasses the "Internal DAC" in the iPod and inputs the given encoded tunes into your external source, i.e. an "External DAC", or your Low, Mid or High end sound system/stereo. With AIFF encoded songs on my iPod, I plug it into the Wadia and all my songs input into a "Benchmark-Media DAC-1", then into a pair of "Dynaudio Acoustics" powered speakers as my set-up. The iPod never sounded this good! This is quite a slick set-up to say the least!! The better your audio equipment, speakers, external DAC and so forth, the better your music will sound, probaly as good as the "Studio Masters". Oh yeah, you can watch videos from the iPod too on an LCD, Plasma etc. TV via. Component Video jacks. A remote comes with the 170i also.
The only negative I've found is that you can not display the cover art or song titles onto a TV via the component video output. The GUI is not accessible from any of the iPods. It is blocked from doing so because of Apple's design not because of the Wadia.
The $379 price tag is mainly for the microprocessor that allows for the audio pass-through to bypass the iPod's DAC. This is the only product on the market, that I know of, which does this and does it extremely well! I hope this was useful info. for those who took the time to read it. Thanks!
I think the general consensus is that these portable players weren't designed for Audiophile-quality consumption.

- Why would anyone buy this? Surely you can just use your PC as the source if you are at home?
