Thinking of Upgrading Speakers


I am going to upgrade my system and I'm curious whether speakers are the right move. My current system is:

Pro-Ject Expression III turntable
Arcam A28 Integrated Amplifier
B&W CM1 Speakers
Sonus player for digital (though I'm primarily using analog as the source)

I'm relatively new to Hi-Fi and have been doing some research on how I want to upgrade the system. A dealer near me has an open box pair of Sonus Faber Cremona M speakers which I'm considering getting, but I'm wondering whether it makes sense to start there.

Does it make sense to get the speakers and then down the road match the rest of system to the speakers? Or should I pass on the Cremona M speakers and upgrade the electronics then match speakers to the electronics down the road.

Thanks for your thoughts!

There's a lot of ways to go about this, but RW's advice above makes the most sense for someone in your position. The only thing I would add is that it sounds like you may be rushing into things. You will definately get lots of recommendations for speakers, but remember that you are the one that has to like them, not us. If you want to make the right choice, it would be good to listen to as much equipment as you can. Your current system is pretty solid. Use it as a baseline for comparison. Sometimes it takes a little while to gain some listening skills in order for you to move forward. If you are not sure about something, just hold off. The best thing to do is keep listening to music and not get frustrated. Do that and everything will just seem to work itself out with regards to your system.
Speakers are absolutely the place to start when upgrading. Your transducers are the key to your overall sound. You don't say what cartridge you have, and that will make a difference about how things sound. If you like the Sonus Faber sound in the store and the dealer has a no-hassle return policy if you don't like them after you get them home, those would be a good place to start.
