Speaker upgrade suggestions


Hello all
I am thinking of upgrading my speakers. My system as of now is a Forte 4 power amp, Forte model 2 preamp, Arcam diva cd192, audioquest jag interconnects, audioquest GR8 speaker wire, and B&W 602 s3 speakers on nice metal stands with a B&W 600 sub. The system sounds good, no question, but... I want more. My opinion is the speakers are the weak link. But I'm not sure, any suggestions or comments?
Thanks, Mcgarick

In response to these comments, I guess I'm looking for more musicality, and a tight lively mid bass, not bloated or over emphasized but a (big boogie groove factor). Maybe a modest floorstander. At the Audio store where I bought the 602's , I did compare them with the 700's and thought the difference to be small in overall quality. I dont want to spend more than $1000 new or used. My forte gear has been sent to Jon Soderburg for upgrade/updates, so I will wait and see what changes that makes before I make a purchase. Thanks for the commments.
Magnepans are great for midrange and midbass, strings so lively you HAVE to air guitar to them and vocals really fly. And you already have a sub so that takes care of the maggies' slightly weaker bottom-end bass if you need it. I use a pair of 15 year old maggies with no sub and they sound great, but I wish I had a sub for when I was watching movies or listening to deep dance music or hip hop, with a lot of very low, loud sounds. The maggies are also wicked detailed, and resolve noticeably more detail than even my grado headphones. They go for $950 new. on audioreview it has a 4.83 out of five from 42 reviews, I'd trust that: http://www.audioreview.com/cat/speakers/floorstanding-speakers/magnepan/PRD_120037_1594crx.aspx

They are also great from a design prespective, they really don't overpower the room and they look very sleek in a home theater setup, you can get them in a variety of finishes as well.
Audio Physic Yara used in the sub $1,000 slim modest floorstanders is a very good choice that will blow away your beewee. They can rock solid if needed and have a big neutral sound. Bohlender Radia Z7 are said to be in the same league and much cheaper (less channel added costs), about $500 used.
Hello
Thanks for everybody's input.
Madmax, I would love to get a pair of Magnepan's, but my room is really not good for them. If I move to a bigger place I will try a pair for sure. I have never heard anyone say anything bad about them, except that their maybe too big.
I did however pick up a pair of a/d/s/ M-12 towers and I must say they are most impressive,
I cannot find a single thing to criticize there sound. I think these will be with me awhile ;^]
I might try and pick up some more ads to try, if I don't want them I think they will be easy to sell.

I also picked up a pair of Polk Lsi9's that are great.
The a/d/s/ m12 sound is more balanced though.
Both are real good.
Thanks for your replies.
