The LCR MKIII is a high quality, dual-mono, pure
analog phonograph preamp. This topology allows a unique application of smaller
inductors that yields an ergonomic approach to LCR (L=Inductor, C=Capacitor,
R=Resistor) phonograph reproduction. Vinyl minded audiophiles are growing in
numbers with collectable, vintage releases often bettering the best digital
formats and new vinyl issues being added to catalogs with increasing frequency.
It is known by many in the audio community that LCR RIAA correction is a
preferred way of capturing the experience and atmosphere of the original
performance.
The passive LCR network is a topology that brings
out the detail of small instrument inflections yet keeps a musical cohesiveness
in context of the performance and room. Advanced hi-speed op-amps allow for
transformerless direct drive of the LCR network. Current sources are employed
to bias each amplifier stage into class A operation.
The LT1358 op-amp is still made in a through-hole
package allowing this preamp to be made with no surface mount parts. One set of
dedicated inputs allows for the simplest path to the op-amp input. There are no
switches between your cartridge and the amplifier. Discrete series/shunt power
supply regulators are used with one dedicated to each amplifier IC power supply
pin. Also for ease of current delivery the pass element of the series regulator
is vastly over-rated in current capacity. No power supply ground shares audio
grounds or left-right channels. Critical components in the audio section are
hand matched. All assembly is done in the USA.
