Classic Sound with Carefully Selected Vintage Tubes Tubes still hold a special place in audio amplifiers, and the XD05T takes full advantage of that with two miniature tubes from the 1960s. These carefully selected, meticulously paired vintage tubes add a touch of even-order harmonics, delivering a soft, warm sound full of emotional depth. Since these rare tubes are no longer in production, they bring a unique, classic "analog" feel that becomes even more precious with time. The Timeless Warmth and Precision of Tube Amplifiers When tube amplifiers operate in high-voltage environments, they generate even-order harmonics based on the original signal. These harmonics, combined with the fundamental frequencies and higher-frequency harmonics, create a fuller and richer sound, delivering a pleasant and immersive listening experience. In contrast, odd-order harmonics can cause discomfort, but tube amplifiers naturally produce fewer of these. This harmonic structure, combined with their dynamic range and micro-detail performance, allows tube amplifiers to excel at capturing subtle musical nuances. Their inherent warmth softens the sound, making them particularly enjoyable for classical music, jazz, vocals, and more. Once a hallmark of high-end audio, vacuum tube amplifiers remain beloved for their distinct, nostalgic sound quality. Hybrid Circuit xDuoo recognizes the crucial role of the preamplifier in shaping overall sound quality. To highlight the distinctive "tube sound," xDuoo integrates a vacuum tube into the preamplifier stage. For enhanced driving power, transistors are employed in the current amplification stage, delivering robust output. When driving 300-ohm headphones, the power reaches up to 556mW, fully unlocking the potential of high-impedance headphones. This hybrid design, combining vacuum tubes and transistors, enables the amplifier to preserve the warm tonal character of tubes while benefiting from the resolution and stable output of transistors, offering excellent compatibility with a wide range of music genres. Rich and Practical Adjustment Functions The XD05T offers three gain levels to adapt to a variety of headphones. The TURBO (L) setting is ideal for IEMs, TURBO (M) suits low-impedance headphones, and TURBO (H) is tailored for high-impedance headphones. This versatility ensures users can enjoy rich, optimized sound quality across different devices. BASS ON – Enhance the Heavy Bass Unlock a deeper, more powerful low-end with the bass boost function. Once activated, the frequency response shifts to accentuate the lower frequencies, delivering a richer and more immersive bass experience. This feature adds depth and impact to your music, perfect for those who love a heavier bass presence. Desktop + Portable – Two Working Modes The XD05T offers dual power options—battery and DC—allowing for both portable and desktop use. When you need desktop-level performance, simply connect a professional Hi-Fi power supply to switch to desktop mode, unlocking enhanced capabilities. For on-the-go listening, the internal battery powers the XD05T, letting you enjoy your music anytime, anywhere.Note: The DC power supply is sold separately. Also, as the device generates heat during operation, avoid placing it in a bag or confined space while in use. Versatile 8-Mode Connectivity With 8 versatile usage modes, the XD05T is designed to meet various audio scenarios. Thanks to its multiple input and output interfaces, it easily connects to a wide range of devices, from phones, PCs, tablets, players, and CD players to DACs and active speakers. The power options include DC IN (12V), and it supports Balanced IN/OUT (4.4mm), Coaxial/Optical IN, Line IN/OUT, and USB IN, making it a flexible solution for all your audio needs. 99 Levels of Precision Volume Adjustment The XD05T uses a digital adjustment chip, offering 99 levels of volume control, allowing for precise tuning of your desired sound level. Even when connected to In-Ear Monitors (IEMs), you can enjoy peace of mind knowing there's no risk of excessive volume.
