jbl gto504 vs. sax-50.4/rd 55.4

They all have good specs and a good rep so what would you go with. A few differences I've noted were a higher signal to noise ratio on the jbl, but the sd and rd have a good channel separation level. The sd also has a subsonic filter. I would like to get something pretty efficient and are leaning towards the sd or rd because of this, but would like to hear what others thought and maybe get lucky and see if someone has owned both and could compare. Also, if you had to choose between the sd or rd, what would you pick. I know they are probably very similar amps, but one maybe a little better than the other. I have not used any of the three and would really appreciate some advice. Thanks.

I have the JBL, haven't played with it but it looks pretty good. I'd say go SD just because it has full active capability...or it should, i haven't ever looked up the specs for it.

I'm not saying you'll use that capability, but perhaps down the road when you learn what it is you might wanna give it a try.
