New expression of the perfect sound search that has characterized Krell since its foundation, Illusion is a stereo preamplifier that shares the same aesthetics of power stages with Krell's iBias technology as well as the brand's exclusive CAST interconnect technology An extraordinary flexibility (optional) in filtering with menu management. Composed, as Krell's tradition of absolute reference preamplifiers refers to, by two independent blocks, Illusion uses a fully balanced monophonic dual-channel topology with separate power for each channel. All the signal gain is realized in circuits executed with surface mounted technology with exclusive subsystems, emphasizing the absence of feedback and an exceptionally generous open loop bandwidth (1.5 MHz). Illusion also works in Krell's exclusive "Current Mode" which, by using current signals, prevents any voltage fluctuations from affecting the delicate audio circuits. As far as the power block is concerned, only discrete components are used in order to respond quickly to the most demanding instantaneous current demands and at the same time present the highest immunity against the most severe variations of the signal coming from the Electric network A transformer of 290 VA and a bank of capacitors that add up to a total capacity of 41,600 uF ensure an exceptional response to musical transients. The Illusion is completed with connectivity to the height of a product of its class and price, highlighting the presence of Krell's exclusive CAST signal, as well as balanced and unbalanced analog inputs and outputs, subwoofer outputs (balanced and Unbalanced) and shots to facilitate integration into custom systems.
