What are the Audiophile recommended Android apps for playing digital media (MP3 and FLAC) for Android phones or tablet? Is there a directory or poll in a forum somewhere in head-fi.org? For a start, I spotted - USB Audio Player Pro. Any others? Thanks.

There's a pair of Zeus book shelf style speakers (ZE700S) at my local 2nd-hand shop - appear in good condition & dirt cheap. I cannot any info about them in google/ altavista/bing etc. The only references to Zeus I can find relate to car speakers! They might've been part of a surround-sound...
