I already have the speakers, and Im finding for an amp to go with it so there is notning much I can do on the speaker side unless I sell it off which Im not planning to. From what you are saying, all the amps I mentioned above should sound the same albeit a slight difference in power which isnt true as they are not on a (high) level where they are already perfect and they both output the same perfect, nuetral and linear signal.
Now the objective side, I would love to see graphs of both before purchasing, that would tell me which one is closer 'perfection' or 'neutral'. Either one or both these amps will screw up in a crucial department or 2 on the charts, and that is what Im trying to figure out. If Amir has tested both, it would be way easier for me.
So get subs or something, those speakers are on the weak side and not particularly noteworthy in general. Different electronics will not make much difference in the bigger picture.
