The ‘character’ of your system will be governed by your choice in speakers. There are a number of points that you should be aware of when it comes to choosing speakers.
1) The perfect speaker does not exist. There are compromises in all speakers, and the speaker that is right for you is the one whose compromises you can live with.
2) Your listening habits and interests will dictate the speakers that appeal to you. If you listen to music at very high levels you will gravitate to a highly efficient speaker. If you listen primarily to chamber music your choice will be different to someone who listens to heavy metal.
3) There is no compromise for size. There is a current trend towards small and aesthetically pleasing speaker designs, and this is one of the compromises above. A loudspeaker works by moving air, and physics dictates that the more air you wish to move, the greater the cubic capacity needs to be. There are many very good small and aesthetically pleasing speakers on the market. Just don’t expect them to sound like a live concert!
