Other companies have it, but we specialize in it. It allows us to get wider bandwidth through the signal path, even though the circuits themselves are a little more complicated and require more parts. Current mode is a domain of current gain as opposed to voltage gain. Obviously, you have to go to voltage gain at some point, but we have as much current gain as we possibly can before we get into voltage-gain stages, which reduces noise.
Lander: You put even more emphasis on current gain when you developed your Master Reference Amplifier about six years ago. We redid our preamps to better match the MRA. The KCT is a complete current-gain preamp. We eliminated voltage-gain stages that we used in the past and replaced them with current-gain stages.
Lander: Back in the mids, you created a separate company called Krell Digital. How was it structured? And what was your rationale? Digital was in its infancy, and we were unable to finance what we wanted to do, which was to create a 64x-oversampling processor in software.
We actually did it in software. We made a whole processing engine, and it cost a little over a million dollars to do that. Lander: And then, between Krell and Krell Digital, you suddenly found yourself with nearly two dozen products—so many they added up to a problem.
Lander: Some of your newest products are loudspeakers. You designed speakers when you worked for Dayton Wright, but that was back in the s. What drew you back into the field? Then I started playing with it on our Master Reference Subwoofer. We applied it and refined it.
Why did you decide to develop a full-range speaker? Have you enjoyed those projects? Lander: Are you currently involved in any consulting projects? And I think that home-theater customers are very likely to buy one brand right through the product line.
Lander: That explains the prototype speakers being auditioned as we speak, in your company listening room just down the hall. How much will they sell for? Lander: Can we expect to see a Krell system for cars? It would be very difficult for us to mount such an effort. Do you intend to make a commitment to DVD-A? It will translate any kind of thing you put in it, so you can do everything, including video, on it. That begins with a raw datastream, a giant brain.
We program it. We write codes and algorithms to make it run. Lander: And you can program-in anything that comes down the program-information superhighway. It costs huge amounts in royalties and upfront money to have these technologies at your fingertips so you can manipulate them the way you want. Lander: Rather than continue using one particular transistor that everyone else was employing, you had Motorola create a solid-state device exclusively for Krell.
What, specifically, is it? An output transistor. The transistor everybody in high-end audio used was really made for switching power supplies in motor drivers, not for audio. Everybody used it because it was robust enough to allow us to have a lot of current and voltage output, but it was relatively slow and had erratic gain.
I talked to the engineers till I was blue in the face but never could get anywhere. Then, five or six years later, we started petitioning them, asking, "Did you ever fix that device? It had the same current and voltage as the other device, 25 amps at volts, but its bandwidth was 30MHz as opposed to 5MHz.
Lander: And have you bought a million? Lander: How many engineers do you have now? Lander: And how much time do you personally spend on engineering? I oversee all the work. Lander: Has being in Connecticut, which has long been a center for defense manufacturing, helped you find skilled technical help?
One of our major metal vendors is a big Sikorsky supplier. The machine shops do work for all the military companies around here. They work to a specification that matches what we need. How is your proverbial punch these days?
Krell Master Reference Amplifiers
Therefore, the Krell factory will remain closed until further notice from the office of the Governor. The most discriminating audiophiles and product reviewers have consistently recognized Krell components for standard-setting performance. Seemingly unlimited frequency response, combined with unerring accuracy and fortitude, extend a tradition that began with the first Krell amplifier; the KSA The KSA was the first high power, high-current, true Class A biased stereo power amplifier available to audiophiles. It was the first Krell product, and its resounding success established Krell as an important new technological contributor to high-end audio. From the KSA to the present, Krell continually "pushes the envelope" of performance in our search for greater amplifier power. Exploration of new technologies, driven by a never-ending quest to elevate the standard of excellence, has resulted in breakthrough audio designs.
