Sorry to hear your first reaction. But, you really need to get them broken in. I would put them pointing at each other and play them 24 hours a day for a week. As loud as possible without disturbing you.
The most likely problem is breakin. Then as someone pointed out, they may be a bit sizzly. If so, tube equipment would be much warmer. Typically, speakers first, then upgrade electronics to optimize... but you want to like the speakers. Did you hear them before buying? You liked them?
