I have a pair of ELAC Debut 2.0 B6.2 in my office run through a Hafler DH-220 (w/Musical Concepts mods) and it sounds anything but torturous. I had Paradigm Atoms 30 years ago and they were good. I have Wharfedale Diamond 10.1s as well that I periodically swap the ELACs with just for a change. They're liquid and their bass is superb for a bookshelf that size. Wharfedale Dentons have been highly regarded as well.
Frankly I don't think you'd go wrong with either brand for what you're putting together.
