Vandersteen Model 1 should work good with your amps. The larger Model 2's need more power. You will probably need to use a revealing speaker cable to get the best results.
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
