Alot of folks think that because something is newer that its better. Not true in this case!I had a chance to "A" -"B" these two pieces with a good friend of mine. I.M.H.O. (and my friends)the LS 2 MK II was much better than the "16". The salesman bent over backwards trying to sell me the "16" but finaly admitted he thought the LS 2 was a better piece. You miye also notice alot of ARC 15's and 16's up for sale. Why? Its all in the ear of the beholder. Can you take the LS 2 to were the "16" is and compare? Try that if you can. Take the LS 2 to a ARC dealer and compare them. Good Luck!
