Designed as an intermediary stage between audio sources and amplifiers, the X-Tube breathes warmth, tonal richness, and natural musicality into both digital and analogue signal paths. It addresses a genuine limitation in modern audio chains: the output stages of many streaming devices, DACs, and budget preamplifiers simply cannot match the quality of the components downstream. The X-Tube solves this, providing a clean, high-impedance tube input and a stable, low-impedance output to drive even the most demanding power amplifiers.\u003c\/p\u003e\n\u003c!-- more --\u003e\n\u003ch3\u003eTwo E88CC Triode Tubes\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the X-Tube are two 6922\/E88CC triode tubes — dual-triode types renowned for their low noise, extended bandwidth, and sonic refinement. The result is an exceptionally transparent buffer that adds the characteristic bloom and dimensionality of valve technology without colouring the signal.\u003c\/p\u003e\n\n\u003ch3\u003eBypass Mode\u003c\/h3\u003e\n\u003cp\u003eAn RCA bypass output allows direct comparison between buffered and unbuffered signal paths — useful for critical listening sessions and for evaluating the X-Tube's contribution to your system.\u003c\/p\u003e\n\n\u003ch3\u003eVersatile Source Compatibility\u003c\/h3\u003e\n\u003cp\u003eWorks seamlessly with CD players, DACs, streamers, phono stages, and preamplifiers. The 470kΩ input impedance ensures minimal loading on upstream sources, while the \u0026lt;33Ω output impedance provides authoritative drive capability to any downstream amplifier.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubes:\u003c\/strong\u003e 2× 6922\/E88CC triode\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz–80kHz ±0.3dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e \u0026lt;0.003% (10Hz–20kHz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSNR:\u003c\/strong\u003e \u0026gt;96dB unweighted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrosstalk:\u003c\/strong\u003e \u0026gt;95dB (20Hz–20kHz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 1dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 470kΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e \u0026lt;33Ω\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnectivity:\u003c\/strong\u003e 1× RCA input, 1× RCA output, 1× RCA bypass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e AC 100–230V, 50\/60Hz; \u0026lt;0.25W standby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (W×H×D):\u003c\/strong\u003e 108 × 105 × 274mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.29kg net\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Musical Fidelity","offers":[{"title":"Default Title","offer_id":54812650078531,"sku":"MF-XTUBE-B","price":599.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/4696\/7399\/files\/MF-X-Tube-front.png?v=1789388988","url":"https:\/\/www.hifihut.ie\/products\/musical-fidelity-x-tube-tube-buffer","provider":"HiFiHut","version":"1.0","type":"link"}
