Facten, I apologize for giving the impression that you were skeptical.
My own speakers are pretty efficient, they're older Coincidents. That being said, it helps to have some power to get the 10" woofers not just playing, but flapping around and pumping out some serious bass. To that end, I've yet to have another tube amplifier outclass the DA60. Even one that is rated for 75+ wpc in pure Class A that a well experienced reviewer felt were twice as strong as that.
After hearing the new Wilson Sashas two weeks ago, and being truly blown away by them, the question after how I could afford them was that owning them would pretty much necessitate me moving away from the type of amplification (low-moderately powered transformer coupled tube) I feel is the best for me, and how would I handle that. Then, my buddy turned to me, and said, "Hey, that DA60 should suit the bill perfectly." Indeed!
A friend of mine, The Doctor (Mechans), uses his DA60 with a pair of JMlabs. He basically sought out a DA60 because he was so impressed that a tube amp could put out that kind of low end performance and smooth, clean, composed, beautiful power.
Trust me, when you see the DA60 in person, its massive transformers will make you take notice. Then, when you go to pick the amp up, you'll know it's got it where it counts.
