Jadis DA 60 Integrated


Been looking at this amp and am curious what it is about the design that requires 8 KT88s to produce 60wpc whereas most other amps e.g. Ayon Spirit 2 require only 4 for the same or close wpc?

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.
I own a DA50Signature rated at "only" 30 watts, it is a pure class A design using four KT88 output tubes - it handles my power hungry Sonus Faber Guarneri Homage at easy, just as my previous Gryphon pre/power combo with the virtues of tubes.

The DA60 is a very powerfull amp, I understand it does not run all times at Class A (but I might be wrong here) and power should not be any issue with it for a medium listening area.

Hope this helps.
Thanks guys, PS I wasn't being skeptical was really just curious about the 8 tubes versus 4 tubes. Trelja, may Iask what speakers you drive with these amps? I have Tyler Linbrook System 2s 89db 8 ohm
