Electrical Disclaimer Description
The Luxman C-03 / C-03B is one of Luxman’s best-regarded solid-state preamps from the late 1980s. The “B” simply denotes the black finish; electronically it is the same as the champagne-gold C-03.
Overview
The C-03 was designed as the matching preamp for the Luxman M-03 power amplifier series and sits in Luxman’s respected “Champagne Gold” lineup.
What makes it special:
Pure Class A line stage
Outstanding MM/MC phono section
Very low noise floor
Excellent imaging and depth
Dual pre-outs for bi-amping or multiple power amps
Strong synergy with difficult speakers and high-current amps
Many vintage Luxman fans consider the phono stage alone worth the price of admission.
Sound Quality Review
The C-03B has a refined, smooth and spacious presentation rather than an aggressive or ultra-analytical sound.
Rich but controlled midrange
Deep soundstage
Excellent low-level detail
Non-fatiguing treble
Powerful and stable bass when paired with M-03/M-05 amps
Exceptional vinyl playback quality
Compared to other vintage Japanese preamps:
More refined than many Sansui models
Cleaner and quieter than older Pioneer SPEC gear
Less “romantic” than tube Audio Research preamps
More neutral than the Sansui CA-3000
Owners often describe the sound as “effortless” and “musical,” especially with demanding speakers.
It stays composed at high output,
has strong bass authority,
and pairs beautifully with high-current Luxman power amps.

The classic C-03B + M-03B combination is still regarded as one of the strongest value vintage Luxman systems available.
This unit is in excellent original condition and operates flawlessly.
Also have an excellent M03, not 3b, in wooden case if wanted. 3k the pair.
