The Nº52 is unquestionably the finest Mark Levinson preamplifier ever. This dual-monaural preamplifier isolates the critical analog audio circuitry from the control section by utilizing a two-chassis approach to provide the purest signal paths possible. The Nº52 features seven analog inputs – three balanced XLR and four unbalanced RCA – as well as a dedicated phono input configurable for moving-magnet (MM) or moving-coil (MC) operation. Two sets of pre-outs are duplicated in both XLR and RCA jacks, while an additional auxiliary pair of XLR and RCA outputs is configurable, for fixed or variable output with independent source selection. This function allows the auxiliary output to function as a third pre-out, a pass-through full-range subwoofer output or a record output.
Reference AV say:
“ The No. 52 is surely a candidate for the best preamplifier currently available in the world today. The advanced design and comprehensive features ensure its absolute reference status in stereo playback, and the standard by which all others will be measured. ”
