Best controller for iPad?

[haggis999]

My current solution for streaming music files from my Synology NAS is based on a combination of MinimServer and BubbleUPnP. I use BubbleUPnP on my Samsung smart phone to direct the files to JRiver Media Center on my Windows PC (acting as a DLNA player). This PC is connected to the asynch USB input on my Oppo BDP-105, which is the only way at present to make the Oppo provide gapless playback via the network.

This does everything I need for classical music, with the one exception that BubbleUPnP is only available for the Android platform. Just to make life difficult, my current app for playing back the MKV movie files stored on my NAS is only available for the iPad.

I would now like to re-explore iPad-based alternatives to the BubbleUPnP controller but have lost touch with what is available since I last looked at this about a year ago. What solutions have others here found to work well with MinimServer?

Ideally, any such app would match BubbleUPnP's ability to provide a simultaneous display of the Track, Work, Composer and Artist in the 'Playing Now' screen. These metadata tags are stored in all my FLAC files (my custom Work tag actually occupies the Album display slot on BubbleUPnP via tag remapping in MinimServer).
