Depends on the budget, Sonus Faber Guarneri Evo's would be nice, butt also cost a bit more than most people want to spend on 80lbs of speaker...
Carnegie Acoustic CSB1's are really nice and available for $400 a pair rite now through gr research {you have to call for the sale} which is about half price...
for under $400 Ascend cbm170's are nice and on sale for $300, if you can live with a simple black box cabinet, they perform very well...
If your budget allows more than the above, the Philharmonic Philharmonitors are nice and around $850...
Magnepan mmg's are around $600...
Ascend sierra 2's are brand new, getting wonderful reviews and cost a little under $1500...
Wharfedale dentons are nice if you want something retro, I own a pair and they sound wonderful and fit the retro look very well.. $1000 pr
Just really depends on your budget and your wants... I own a lot of bookshelfs, they all do something different, if you like piano black and the csb1's are in your budget, they are an amazing value, I would imagine you need to step up to around $1000 to really better the value... but thats just what I hear... we all like different stuff..
