By the Way just to qualify my statement, I have owned Kimber, Audioquest, XLO stuff all in the 500-1000.00 range, however not on the definitions, and I would say my results with the libtec's are at least what I would get with any of those on my previous speakers and possibly beyond.. For the record I think the main thing that bugs me about the WAX and IBIS is the Supertweeter sounds a little more like a Supertweeter where the Libtec just seems to never let it get out of control, totally smooth at very high volumes, just more natural to the speakers voicing, of course in my opinion and my short but rather decent auditioning.
