Thanks for your impression. I have a Q701 on the way and i hope the DACport doesnt dissapoint. Will leave my impressions soon :)
I have this exact combo. After weighing the cost of any good quality dac and amp the value proposition of the dacport appealed to me. I bought some 702's on this forum and have listened to the combo extensively.
Its very good. Not quite great, but good. As the reviews say, the 702's have no bass. The smallness of the dacport does not help this much, but in reality it makes a good match. At first one might think the bass is thin due to the dacport, but in reality it is the quick, articulate but very light bass that characterizes the 702. The dacport has a warm sound to match its temp so it matches well to balance the detail oriented nature of the 702. I've enjoyed the combo very much and on the used market you can probably score both for around 500 bucks. Thats a great price of entry into lossless computer audio and even when you outgrow it the dacport always finds use because it is so portable.
The short version: the dacport can handle the 702. if you like the 702 sound the dacport is a great way to hook your pair up to a PC or mac or lossless audio goodness.
