Anybody heard about these? Seem to have good specs 30hz - 18khz, 120 db dynamic range, adjustable bass boost, rack mountable, XLR and 1/4" outs, etc, etc. More info at http://www.nady.com/products/product_pgs/u33b_pg.htm . Musiciansfriend is blowing these out at $149 even though they are new. Anybody try one or care to speculate?
