I already own the Sierra Towers for my living room (100% classical music). I now want to have a spare bedroom setup so that I can also use it for my primary dedicated music listening as well (since my daughter and baby grandson have moved in with us).

I currently have two 16 year old B&W 602 S2 bookshelf speakers that I've moved to this bedroom. They were highly regarded in their day and cost $600 for the pair.

Will buying the Sierra 2's be a noticeable upgrade for my classical music listening in this spare bedroom? The room is about 10 x 14 with sloping ceilings on two sides and I've been told this is a better environment than a square box room. Money is not a major concern but I'm cheap and don't want to spend money on something I won't really notice. BTW, my son has the Sierra 1's and I was really impressed at how great they sounded in his home theater set-up.

Thanks for any advice.
