Just wanted to do a little thread necromancy here as I've stumbled upon something cool. I've been struggling with finding a quality audio player for iOS that can run my wireless drive as a media streamer to my iPad which can in turn sends a digital signal out to an iFi iDSD Micro. Every link in the chain is battery powered now. I just need an app that has both DLNA compatibility to access my drive, and a good in built equalizer for my subwoofin, lowriding tendencies.
There are plenty of good Equalizer apps like EQu, Sonic Max Pro, and Equalizer and there are good DNLA streaming apps like 8Player and MConnect but it's been tricky finding something that does both.
I found Neutron Music Player on the apps store and as best I can tell is has a robust set of Equalizer/DSP tools as well as DLNA, compatibility, Wav, FLAC, ALAC & AIFF compatibility. It does high res for those who use that, but apparently no DSD... Some out there may consider this a deal breaker. I am a Redbook guy so this is of little significance.
Features include.... Parametric EQ, Surround DSP, Crossfeed, Rumble Filter DSP (low cut), dithering, pitch and tempo adjustments, volume normalization, replay gain, gapless playback, downmix to mono, and a spectrum analyzer.
Only knock would be the app is optimized for iPhone 5 with no iPad specific version (so it looks a bit overwrought on iPad) and the interface is a little rough looking. That aside... It's turns by deactivated iPhone 5 into a top notch transport.
