Forget about the 60 wpc rating. In fact, it will also easily eclipse those figures running EL34 output tubes. As the literature says, the numbers are incredibly conservative. Think of the traditional Rolls Royce answer in regards to their horsepower figures, which was given with a most confident smile, "Adequate."
The Jadis DA60 is a beast. The proverbial iron fist in a velvet glove. It's truly one of the finest audio amplifiers from the standpoint of both build and sound, and will go toe to toe against anything.
Another thing, you have to remember the amplifier operates in Class A, which normally looks half as powerful as Class AB on paper even if that totally goes against real world seat of the pants power.
As an example, I've also owned the Orchestra Reference and DA30. The JOR is rated at 40 wpc (or, I was told via e-mail with the company, 52 wpc with the KT90 tubes I had) in Class AB, while the DA30 is rated at 30 wpc in pure Class A. Regardless of the numbers, the DA30 walks away from the JOR ala its superior transformers, power supply, and circuit.
Currently, I own the DA30 and DA60. In direct comparison, I feel the DA30 is probably a bit more sweet. So far, I cannot totally put my finger as to why. It could be because it's an older vintage, and like most audio components, the direction of things has been more resolution, clarity, refinement, etc., and sometimes, less romance and musicality. Or, it could be that the midrange of the DA30 stands out more simply because the DA60 offers such absolutely incredible low frequency performance.
Compare it to ANY 2 6550/KT88/KT90 tube per channel amp, and all of your skepticism will immediately vanish.
