Tvad , you owned version AKM # 5 and we are up to revision #14 . I owned AKM version # 12 . What I was referring to was in non technical mathematical terms my friend . It was basically on a laymans scale. 1. was Crystal 4. was my AKM and although I initially intended to place the 2.5 as a simple 10 , I gave it some thought and came to the conclusion it was higher in relative performance. I wasnt intending this to be taken too terribly seriously. I was simply trying to put this in to perspective for some out there who might wonder where the performance values lie. It was a relative scale not based on percentages . My mistake I guess. Audiophiles are certainly a serious group of people..... :} I represent APl Hi Fi yes , I also have fun in this hobby and will exit quietly when it ceases to become so.
