Ive had a few ART and the DBX, for clean straight broadcast I'd go with DBX, with more transparent comp/limit of those two.
Actually the Symetrix 528e used is $1000 unit that sells cheap at times, its very quiet and has one of the best noise gates/expanders Ive heard, again transparent and clean.....no musical harmonics and tube transformer stuff...Symetrix 528e were $80 a year or so ago, now they all seem to be $300 or not available.
(has to be the 528-E or the old ones have the funky wire plugs on the back)
my 2 cents as a hobbyist the ART stuff channel strips were more tone shaping and didn't have the heavy metal industrial build feel, which isn't a problem for me because I don't drag gear around anymore. I currently have a LA610 and wouldn't suggest that for Broadcaster clean either and the compression on it definitely isn't transparent imo.
DBX, Symetrix, Grace, ISA stuff has nice clarity. ..solid state. Id go for the DBX 286 over the 386 too, for the solid state version.
