I would agree. Save your money on the amp. Amps are great, but not all speakers justify the cost. The larger the speaker, the larger the listening space, and the louder you like the sound, then amps come into play. But I would say that you would need to fall into the "larger/louder" crowd for all 3 of those criteria before really needing to jump into it.
Of course, if you have money to blow, then do whatever you want. Bang-for-the-buck just isn't there with your setup in my opinion. Others may say otherwise, and that is fine too. I just don't think that you will get the definitive "YES/NO that you want.
