Good morning to all.

I'm ready to upgrade my Aiwa Shelf system from 1994, it's 25 watt per channel with 2 Book shelf speakers(6 ohms).

I'm looking at the Marantz PM6005 Integrated Amp paired with either the Klipsch Reference Premiere RP-160M or the Polk Audio RTi A3.

The room is 12x15 and I like it loud, my current system is loud enough, I'm just looking for better sound.
I mostly listen to Disco, yes, I said Disco. LOL Some reggae, rock, Santana, Marley, Barry White, ect.

Is this 45watt amp enough for my speaker choice?

Will the Klipsch be a better match than the Polks? What say you all?

Thanks, Red

EDIT: All my music at the moment is on my MacBook, I will add a CD player and possibly a turn table in the future.
