In the first part of this interview, I talked with Murali Murugasu and David Payes about the genesis of Constellation Audio and its products. In this second part, I find out specifics, including who is designing these new-to-the-market extreme products.
Michael Fremer: Let’s talk about what you showed here at the CES.
Murali Murugasu: We showed an SACD player [renamed Sirius HD Music Source], which consists of a transport section with a DAC section with the power supply integrated in. We showed a preamplifier with its own power supply. We showed a stereo amplifier, which is going to output 500 watts into 8 ohms, and we showed a mono amplifier, which is going to output a thousand watts into 8 ohms. And we also showed a prototype server.Fremer: A what?
Murugasu: A server.
Fremer: I didn’t see that but --
Murugasu: And currently what we’ve done with it is we sourced some high-definition recordings from Reference Recordings and put it into USBs. I saw this server, a concept of it, some time ago in the US, and then they implemented it for us. So that’s that section. Then we were talking about the amplifier, and Peter said, “I know just the guy.” And he said, “I’m not sure whether he will want to do anything, but I’ll speak to him and tell him.” He’s happy to look at it, but he is a shy and retiring type. He likes to not be in the forefront. His name is Bascom King. And together with Peter, they presented a couple of designs to us. So we had a look at that. And they eventually settled down on a particular topology for the amplification stages, which is a single-ended MOSFET design. The idea behind that was, we have this thing for class-A power and putting it out, even though there are heat issues with it. And this topology, they believe, maximized how much you could get in that sense. So that was the amplification section in terms of sorting that out.
