Up for sale is a completely stock Zhaolu 2.0 with the CS4398 DAC chip. I purchased this from IFI Audio a couple of months ago and I still have the original box. It's a great entry level DAC, but I'm personally moving up the ladder. I'm looking for SOLD shipped CONUS, with Paypal payment. If you want me to install a Zapfilter for you, PM me separately about it. My feedback is here.
