let me be clear on a couple of things........1.i do not consider allison ic20's as one of the best allison designs. 2.the last generation of allison one's will compete with any 30k speaker made today in regard to tone....3. i have no opinion on the actual sound of BRSE, because i've never heard them. 5. when someone does take the plunge, post a review and tell it like it is.
