I have a Rotel RBX980 120W/ch amp with a RTC980 pre that I recently bought for a great deal. I understand they are rather on the bright side as a combo and wish to match them up with a pair of bookshelf speakers that would add some warmth and decent bass extension. I mostly listen to rock / r&b / jazz. My budget is $250 tops for the pair. What are some good options for new or used that you can recommend? thanks for everyone's time!
