It will never has as much oomph as an M70, even with a woofer swap because it only has 2 amplifiers compared to the M70’s (4), so if it’s all about volume, then the M70 wins. But just because it’s not as loud doesn’t mean it’s not also a kick-A Boombox. Has a lot going for it such as an M90 style deck (I think it also uses the same high quality heads as in M90), but it also has that unique tuner that while really isn’t anything better reception wise but at least it’s a novel approach to all the cookie cutter designs. Nobody else except that Citizen (& associated aka’s) has that tuner so it’s great for someone that wants something different.
