Sensativity is not the only thing to look at. For example, Wilson speakers have high sensativity but really demand BIG POWERFUL amps. Many others are similar. Again, try before you buy.
Tube Friendly Speakers
I need a pair of speakers that my 25w per channel monos can handle, one of my audio pet peeves is an underpowered speaker, so I need something that 25 watts can really move, I am trying to keep it under $2000 new, I've thought about trying the Triangle Antal xs but I have no where to audition them, any other recommendations
