Expert Insight
LUXMAN is one of the few audio brands that’s actually been in this business even longer than I have—and that’s saying something! I’ve always associated LUXMAN with absolute excellence. Not the lowest price, but the best sound, which is exactly what matters most. After all, if you’re considering a stereo vacuum tube preamplifier, you already understand that performance and musicality come first.

LUXMAN CL-38uC Vacuum Tube Preamplifier
The Luxman CL-38uC is a beautifully crafted vacuum tube control amplifier (tube preamplifier) designed to deliver rich, natural musicality with modern connectivity and precision. Built around SRPP (Shunt Regulated Push Pull) circuitry in all stages, it provides a clean, stable signal path with low distortion and a refined, tube-forward presentation that stays detailed and accurate. A genuine built-in phono equalizer supports both MM and MC cartridges, with MC-low and MC-high gain/impedance options using independent MC transformers and a convenient selector lever for quick matching to your cartridge. To tailor your system exactly to your room and taste, the CL-38uC includes tone controls with selectable turnover frequencies, plus a low-cut filter for improved control of rumble and unwanted low-frequency energy. Finished with Luxman’s classic styling and a traditional wooden case, this control amp also adds balanced inputs (transformer-equipped) and includes a compact aluminum remote for smooth volume control from your listening seat.
Note: 19mm front panel knob and 12mm rear panel terminals are included in the depth measurement
Net weight
13.3kg (main unit)
Accessories
Remote control (RA-19), Power cable
Balanced input note
Transformer-equipped balanced inputs; maximum balanced input level equivalent to 2.5V (higher-output devices may distort).
LUXMAN CL-38uC Q&A:
Is the CL-38uC a preamp or a power amplifier?
The CL-38uC is a vacuum tube control amplifier (preamplifier) designed to manage sources, phono playback, and volume control before sending signal to a power amplifier or active speakers.
Does it include a built-in phono stage for turntables?
Yes. It includes a genuine phono equalizer that supports MM cartridges and MC cartridges with dedicated step-up transformer support.
What MC cartridge options does it support?
It supports MC high (0.3mV/100Ω) and MC low (0.08mV/30Ω), each with independent MC transformers, selectable via the MC impedance lever switch.
Does the CL-38uC have balanced (XLR) inputs?
Yes. It adds transformer-equipped balanced inputs to improve compatibility with high-end sources and system layouts.
Is there anything to watch out for with the balanced inputs?
Yes. The balanced inputs have a maximum input level equivalent to 2.5V; connecting a device with a higher output voltage may cause distortion.
Can I adjust bass and treble on this preamp?
Yes. It includes tone controls (±8dB) with selectable turnover frequencies—Bass: 150/300/600Hz and Treble: 1.5k/3k/6kHz—for precise, musical tuning.
Does it have a low-cut filter for rumble or unwanted bass?
Yes. The low-cut is set at 30Hz (-6dB/oct.), helping reduce turntable rumble and very low-frequency buildup.
What tubes does the CL-38uC use?
The tube complement is ECC83S × 3 and ECC82 × 5, chosen to support its SRPP circuit design and overall sonic performance.
