This product is the work of Jam Somasundram, who joined us early this
year. He's an old friend of the company, and previously consulted for Wadia
and Sumiko, and designed two amplifiers for Cary. A big fan electrostatic
loudspeakers (Stax headphones and Soundlabs panels).

Thanks for your kind words Michael.

I have known Mr.Pass for more than thirty years and he has been one of my mentors and has had a huge influence on my career. Getting the opportunity to join the Pass design team has been a dream come true (in other words play in Nelson's and Wayne's sandbox. I like to think of it as the Silicon Skunkworks)

What I have designed reflects ideas learned from Mr.Pass and other noted designers with my own take on the final implementation, while keeping with the Pass tradition of quality and excellence. Kudos to Desmond Harrington, for the design and cosmetics of the chassis. We have a talented group of people here that have contributed to this project.

I would like to thank Mr.Pass for the opportunity to design this amplifier and his kind input and advice.

Jam can you tell us a little bit about this design and what you reckon, modesty allowing, makes it special ?

I just don't like that neutrik locking plug! Is it necessary because of the amplifiers design?

Some amplifiers without output protection fry the output devices when the user removes the jack and momentarily shorts the channels to ground.

Other wise it's a beautiful design and would love to see some pictures from the inside!

Jam has corrected me - he came to PL last year.
