got mine a week ago and has been running non stop since.
about the same or maybe a tad better than playing apple lossless via optical connect into the grace dac.
currently, the 170i is connected to the grace dac by coaxial, the same non brand cable wadia packed along with the itransport.
i have on order a couple of more expensive coaxial 75 ohms cables. hoping to hear some difference when they arrive.
sonically, this combo is hard to beat
only a few issues.
1) wished that remote sensor blue window in the front of the 170i lights up. rather boring right now.
2) with every ipod except the iphone or itouch, you cannot play with the ipod once 'docked and digitally locked' with the 170i. only way to change songs is to track forwards or take the ipod out of the dock..
this means wear and tear. wonder how much replacing the dock male postings cost and if it is DIY?
3) no optical input
