BitPerfect for Mac vs Pure Music

I just installed BitPerfect and began using it. Have been using Pure Music up til now. In my system the BitPerfect has revealed a startling layer of detail I've not heard before with my music. Mids, seem a little harder, tho not harsh as when using iTunes alone. Pure Music is easier on the ears to a small degree, but seems muffled by comparison. I understand all our results may vary, but I'd appreciate hearing your experiences and thoughts regarding this software. Its native file format automatic switching is a nice feature....but worth its sound?
