I think both JPlay and Bug head Emperor are suitable for those that like to tinker around with their hifi in pursuit of the highest possible SQ.
But they are not suitable for those that prefer an all round music player that has good SQ, but also good UI and library management.
I have tried JPlay about a year ago, but it's UI was unbelievably crude as a standalone music player. Along the lines of: Open up a DOS-like window, go to your music folder and select some files and copy&paste them into the DOS-like window. Apologies if they've moved on since then, but JPlay makes much more sense if used as a plug-in to another music app. I gave up when JRiver deliberately prevented JPlay from being allowed as a plug-in.
I never tried BHE because I was not prepared to spend 3 years contemplating the meaning of life in an isolated monastery in the Himalayas - just to be able understand what the BHE's creator was on about
