iTunes & Bitperfect not perfect

I purchased Bitperfect to use with iTunes when I added a Mac Mini to my setup based on Paul’s recommendation. Then I find out that the combination of iTunes & Bitperfect has issues with gapless playback. Bitperfect blames iTunes & to my knowledge still has no solution. I am wondering if anyone has explored another app. to use with iTunes. I have switched to J River MC23 & am happy with it, but would like to see if iTunes has anything to offer in other ways. Mainly bothered by J River’s UI.
