Vanguard is a product that appears under this design concept. According to the official statement, Vanguard is composed of Illusion's pre-level plus iBias' post-level. This means that the Vangurad merger also has the line design and technology that Krell has always used such as self-bias, CAST transmission, and discrete class A preamplifier. It can be said that the essence has been integrated into Vangurad. Krell has always been called "Hercules", so the design of high power output is a must. Vanguard's output power is 8 ohms 200W, 4 ohms doubles to 400W, which is fully in line with Krell's character. The most important thing is that even with such a high power output, it is not bulky, only the same size as the Connect streaming media player, and the heat sink is not exposed at all, relying on the chassis and two fans to dissipate heat. However, these two fans are actively cooling, and the temperature inside the machine needs to reach a certain level before they can be turned on. The operation of the fan is very quiet, even if it is running, you may not necessarily feel it. In addition, Krell also specifically marked the damping coefficient value of the power amplifier. Vanguard's full-band damping coefficient is around 106, which is not particularly high. In theory, the higher the damping coefficient, the stronger the control of the unit. But the theory is not the theory. In fact, it is not so. The control is too strong, the sound will sound tough and tight, especially the low frequency will lack the bounce and loose feeling. Conversely, a power with a lower damping coefficient will give a more relaxed and warm tone on the sense of hearing. For example, the amplifier is a good example. So, choosing the right damping coefficient is the most important, and Vanguard's purpose is exactly that!
