1060

Stereo Power Amplifier

The 1060 Stereo Amplifier is infused with over 30 years of experience in amplifier design. You can feel it in the build, which is weighty and solid. You can see it in the construction, which has the best fit and finish in the business. And you can hear it in the performance, thanks to its excellent resolution and control.

Not your average amplifier then, but an extraordinary one. As a Boulder, it’s exactly what you would expect it to be.
