I like the JBL too but they have really gone up in price, Legacy Audio would be a great choice as well as Dynaudio and Martin Logan. I would not bridge the MC2300 because it will raise distortion levels and make the amp harder to listen at loud levels. I like Klipsch too, many of there models are pretty sensitive. Just get some speakers that are more sensitive like 90db or better and your 300watts X2 will be more than enough.
