I’ve been using this dock for the upcoming Matrix Mini-i and Dr. The Onkyo dock, coupled with a nice DAC with built in amplifier, and you’re good to go. The nice thing about this, however, is that if you want to have a separate headphone listening set up away from your computer. Of course the limitation is the 16/44.1 digital format (limited by the Ipod), so in a way, you’re spending extra money on this digital dock while a PC or laptop could’ve done a better job with a 24/96 USB DAC like the Audinst or the Dr. It’s also cheaper for roughly $250 (less if you buy from ). ![]() It does the same thing as the Wadia i170, only it’s a little less buggy, has PC/Mac connection, and comes with a better remote control. The digital dock accesses your Ipod hardisk and outputs digital data for pairing with an external DAC (hence you’re not limited by the quality of the Ipod DAC). Finally I was able to get one of these beauties. ![]()
