Luxman E-250
Beschrijving / Description
A complete phono equaliser designed for rich vinyl playback
The E-250 is the latest phono amplifier from LUXMAN, inheriting the best in design from its predecessor the E-200 that has been the reference model for compact phono equalizer amplifiers since it was released in 2008. A newly added function to the E-250 is the switching capability of load impedance and load capacity according to the cartridge characteristics for the ultimate enjoyment of the original detail of analog reproduction. The E-250 allows the listener to adjust the fine settings for every performance, releasing the expression engraved in the grooves and creating a hitherto unknown musical impression.
Optimizing the cartridge load adjustment
The rear panel is equipped with a load impedance selector (34k/47k/56k/100kOhm) and a load capacity selector (0p/100p/220p/320pF) to match the characteristics of the cartridge and exploiting it to its full potential.
Specially selected embedded MC transformer
The E-250 features a step-up transformer with a 2 stage gain selection function in which a L/R independent super permalloy core is used, thereby supporting even low impedance MC cartridges. This creates a rich and expressive musicality that is only possible by boosting of the transformer.
NF Type equalizer circuit
The NF type equalizer circuit in the E-250 features many of LUXMAN's original and custom built parts. This equalizer has a high S/N ratio which reduces noise by connecting the first stage FET in parallel. A monaural switch when playing a monaural record is provided as well as a low cut switch that cuts out low frequency signals that can be generated by distorted records.
