My portable DCC players have an even worse W/F.
My best 170 has 0,5% (DIN weighted) and the worst one is around 2%.
DCC130 seems a little bit better.
My desktop players have far better specs, they vary from 0,13% to 0,3% (weighted DIN).
-edit-
Non surprisingly Philips does not mention any W/F specs in the analog audio section of the (service) Manual.
