KRELL ILLUSION II DAC PREAMPLIFIER
PREAMPLIFIER WITH DAC
Created to perfectly complement the next-generation mono and stereo power amps from Krell, the Illusion II is a stereophonic preamp that constitutes the latest expression of the search for sonic truth that has characterized the legendary American firm since its founding. Simplified version - in that it uses a single chassis instead of two - of the Illusion reference stereo preamplifier, the Illusion II is a very high performance stereophonic preamplifier that shares the same aesthetic and electronic design concepts as its older brother. Thus, the circuit topology is also double monophonic and fully balanced operating in the “Current Mode” of Krell, the sections corresponding to each channel being fed by an independent regulation scheme that starts from a 95 VA transformer and a 40,000 uF capacitor bank. The Illusion II also does not use negative feedback, while its bandwidth of more than 1 MHz allows it to express the harmonic and spatial contrasts of music with exceptional realism. On the other hand, it has a volume control based on a balanced resistance ladder and designed not to interfere with the bandwidth or the response to transients. As a differentiating element with respect to its older brother, the Illusion II also provides the possibility of managing digital sources thanks to a module specifically conceived for this that admits signals of up to 24 bits // 192 kHz from a maximum of 5 sources (1 coaxial professional AES / EBU, 2 S / PDIF coaxial and 2 EIAJ-TosLink optical). The comprehensive connectivity consists of balanced and unbalanced analog, CAST and control jacks.
