You're making me want to have a look at the Series 5 even though I have a ZS5 sitting in my cart on GearBest. Looking forward to review of those as well. They'll be interesting to pair with the future DAP (I replied to your blog on your blog). An exciting time to get into ChiFi.
Definitely scoop up the ZS5 anyway since they're surprisingly cheap. Could easily make your money back if you don't like them. Fingers crossed the rest of the Exclusive series is worthy of two thumbs up.
