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.\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/listenup.com\/products\/luxman-cl-38uc-tube-preamplifier\"\u003e\u003cspan

+ 25W) and supports 4Ω, 8Ω, and 16Ω loads.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat vacuum tubes does the MQ-88uC use?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eThe tube complement is ECC83S ×2, ECC82 ×2, and KT88 ×4.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eDoes it support different speaker impedances?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes—there are independent speaker terminals for 4Ω, 8Ω, and 16Ω to help match a wide variety of speakers.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat is the “triode connection” and why does it matter?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eThe MQ-88uC uses a triode connection for the output tubes, which is commonly associated with a more transparent, refined presentation and strong tonal realism.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan I use it in a simplified, source-direct setup?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes—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.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat is the frequency response of the MQ-88uC?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eIt is rated at 20Hz–20kHz (+0, -0.5dB) and 10Hz–100kHz (+0, -3.0dB), supporting both accurate bandwidth and
