My choice would definitely be the KEF speakers.

IMO the Polks are too strident in the upper midrange and do not have good midbass sound quality.

The KEFs are far better IMO.

Hi all!

I am looking for the best "under $1000" bookshelf speakers. I live in Costa Rica, where I don´t have many options, so I am deciding between a pair of KEF Q300´s or a pair of Polk Audio LSi7´s. I want to use them with these italian integrated amplifier and CD player, which are greatly musical.

I am more into classic, jazz, and "unplugged" music than into rock or electronic. I know that choosing speakers is a very personal decision, but I would appreciate your thoughts about this. Kind regards!
