Id rather just use wav than alac.
Anyway further use of Equlizer Pro has me all wrong about its negatives.
Best thing i found to do with EQ pro is turn off any apps in background you dont need & it seems to play flac almost perfect if you just leave it. Dont search or use any other apps while playing & its fine. The ipod gets somewhat warm when the app is open on screen, so I return to the main icon screen & it seems less warm.
That way just play a whole playlist which can be hours.
Also this app can not play heavily compressed mp3 without excessive stuttering. But i dont care Flac is my main format.
