Features & Specs
25W + 25W output with 4Ω / 8Ω / 16Ω support
Delivers stable, musical power and provides dedicated taps for common speaker impedances to help optimize matching and overall control.
KT88 triode-connected output stage
Uses KT88 tubes with a triode connection to emphasize tonal purity, a transparent midrange, and the natural timbre tube amplifiers are known for.
Mullard driver and Mullard-compatible push-pull design
Incorporates proven circuit topology to achieve strong musical drive with very low distortion across the rated power range.
Independent impedance-matched speaker terminals
Separate terminals for 4Ω, 8Ω, and 16Ω help bring out the best performance from different speakers without relying on a one-size-fits-all output.
Variable input mode with input-stage bypass
Offers a mode where the signal can bypass the input section, supporting a simpler, more direct source-to-amplifier path when desired.
Heritage-inspired design with premium build focus
Combines a modern-classic exterior finish with engineering choices aimed at sound quality, including careful parts selection and refined internal layout.

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 amplifier, you already understand that performance and musicality come first.

LUXMAN MQ-88uC Vacuum Tube Power Amplifier
The LUXMAN MQ-88uC is a high-end vacuum tube power amplifier built for listeners who want the classic glow, harmonic richness, and lifelike presence of tubes—without sacrificing clarity, control, or modern reliability. Styled in an elegant dark brown finish inspired by LUXMAN’s legacy designs, it blends a timeless “modern classic” look with carefully updated engineering and premium parts selection. At its core is a KT88-based output stage using a triode connection and a Mullard-compatible push-pull configuration, delivering a refined, transparent timbre and stable, low-distortion drive across real-world speaker loads. With dedicated 4Ω, 8Ω, and 16Ω speaker taps and a variable input mode that can bypass the input section for a more direct signal path, the MQ-88uC is designed to integrate beautifully into both traditional separates systems and streamlined, source-direct setups.
Depth measurement note: 17mm front panel knob of and 28mm rear panel terminals are included in the depth measurement
Net weight: 16.1kg (main unit)
Accessories: Power cable
Speaker terminal (Supported Y-lug terminal dimension): Width of part a: 14.5mm or less
Speaker terminal (Supported Y-lug terminal dimension): Width of part b: 7.5mm or more
Speaker terminal note:Connection may be difficult depending on the shape of the Y-lug terminal.
LUXMAN MQ-88uC Q&A:
What type of amplifier is the LUXMAN MQ-88uC?
It’s a vacuum tube power amplifier designed to deliver the warm, accurate character of tube sound with improved clarity and modern engineering.
How much power does the MQ-88uC output per channel?
It delivers 25 watts per channel (25W + 25W) and supports 4Ω, 8Ω, and 16Ω loads.
What vacuum tubes does the MQ-88uC use?
The tube complement is ECC83S ×2, ECC82 ×2, and KT88 ×4.
Does it support different speaker impedances?
Yes—there are independent speaker terminals for 4Ω, 8Ω, and 16Ω to help match a wide variety of speakers.
What is the “triode connection” and why does it matter?
The MQ-88uC uses a triode connection for the output tubes, which is commonly associated with a more transparent, refined presentation and strong tonal realism.
Can I use it in a simplified, source-direct setup?
Yes—the MQ-88uC includes a variable input (volume adjustable) mode that can bypass the input section, allowing a source device to connect more directly to the output section.
What is the frequency response of the MQ-88uC?
It is rated at 20Hz–20kHz (+0, -0.5dB) and 10Hz–100kHz (+0, -3.0dB), supporting both accurate bandwidth and extended range.
Are there any compatibility notes for speaker lugs?
Yes—Y-lug terminals should be within the stated width dimensions, and connection may be difficult depending on the lug’s shape.
