Balanced ports deliver dramatically superior sound quality compared to conventional single-ended connections, with marked improvements in channel separation, detail resolution, soundstage width, and noise floor. The result is pure, transparent, and well-layered audio reproduction that faithfully preserves the original recording.\u003c\/p\u003e\n\u003ch2\u003e5U4G Tube Rectifier — Authentic Tube Power\u003c\/h2\u003e\n\u003cp\u003eTwo 5U4G tubes handle high-voltage rectification, supplying independent anode voltage to the left and right channel tubes. This tube rectification architecture is a hallmark of classic high-end amplifier design, delivering the rich, authentic tube sound character that solid-state rectification simply cannot replicate.\u003c\/p\u003e\n\u003ch2\u003e12AU7 Tube Preamplifier — Warm, Fatigue-Free Midrange\u003c\/h2\u003e\n\u003cp\u003eTwo matched and screened 12AU7 dual triode tubes handle preamplification, imparting the signature warm, mellow tube timbre. Even after extended listening sessions, the 12AU7 stage remains smooth and natural — free from harshness or fatigue, making the TA-68 ideal for long, immersive listening.\u003c\/p\u003e\n\u003ch2\u003e6C19 Tube Buffer — Powerful Current Amplification\u003c\/h2\u003e\n\u003cp\u003eEach channel employs two matched 6C19 power tubes for current amplification output. The 6C19 contributes a warm, soft, and exquisite sound character with a charming listening experience, handling demanding headphone loads with authority and grace.\u003c\/p\u003e\n\u003ch2\u003eSwappable Tube Design — Personalize Your Sound\u003c\/h2\u003e\n\u003cp\u003eAll tubes in the TA-68 use socket-mounted construction, allowing users to freely swap tubes from different manufacturers to explore a wide variety of tonal characteristics. Tube rolling is one of the great pleasures of high-end audio, and the TA-68 is built to encourage it.\u003c\/p\u003e\n\u003ch2\u003eDual EI Transformer Isolated Power Supply\u003c\/h2\u003e\n\u003cp\u003eTwo low-noise, low-flux-leakage EI power transformers provide fully independent power feeds to the left and right channels. This dual transformer design eliminates inter-channel crosstalk at its source, delivering cleaner power and remarkably transparent sound — a level of engineering typically reserved for reference-grade amplifiers.\u003c\/p\u003e\n\u003ch2\u003ePremium Audiophile-Grade Capacitors\u003c\/h2\u003e\n\u003cp\u003eVISHAY audiophile capacitors serve as coupling capacitors, delivering transparent, sweet, warm, and pleasing tone. Audio-specialized Nichicon capacitors function as filter capacitors, providing a smooth and mellow tonal foundation with gorgeous, extended, and naturally transparent highs. Every passive component in the TA-68 has been selected for its acoustic contribution.\u003c\/p\u003e\n\u003ch2\u003eIndependent L\/R Volume Control\u003c\/h2\u003e\n\u003cp\u003eSeparate volume knobs for the left and right channels allow precise single-channel trimming to correct any channel imbalance and achieve perfectly centered soundstage performance — a feature rarely found outside of professional-grade equipment.\u003c\/p\u003e\n\u003ch2\u003eAnti Power-On\/Off Thump Protection\u003c\/h2\u003e\n\u003cp\u003eA built-in relay intelligent protection circuit incorporates a 45-second warm-up delay upon startup. This fully preheats the tubes before signal is applied, bringing out rich and authentic tube sound while suppressing loud thump noise during power cycling and preventing inrush current from damaging headphone drivers.\u003c\/p\u003e\n\u003ch2\u003eComprehensive Input \u0026amp; Output Options\u003c\/h2\u003e\n\u003cp\u003eThe TA-68 is equipped with RCA, 4.4mm, and XLR balanced inputs for seamless switching among various audio sources. The output section offers three options: 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR balanced — compatible with the vast majority of headphones without additional adapters.\u003c\/p\u003e\n\u003ch2\u003eAluminum Alloy Chassis\u003c\/h2\u003e\n\u003cp\u003eThe TA-68 is housed in a sturdy aluminum alloy enclosure with a finely sandblasted front panel for a premium, solid texture. The chassis provides excellent EMI shielding to block external stray interference and maintain pristine signal integrity throughout.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e xDuoo\u003cbr\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e TA-68\u003cbr\u003e\u003cstrong\u003ePower Supply:\u003c\/strong\u003e AC 100–120V \/ 220–240V\u003cbr\u003e\u003cstrong\u003eBalanced Headphone Output Power:\u003c\/strong\u003e 330mW @ 300Ω | 240mW @ 600Ω | 120mW @ 75Ω | 160mW @ 150Ω | 200mW @ 250Ω\u003cbr\u003e\u003cstrong\u003eUnbalanced Headphone Output Power:\u003c\/strong\u003e 210mW @ 300Ω | 160mW @ 600Ω | 60mW @ 75Ω | 100mW @ 150Ω | 130mW @ 250Ω\u003cbr\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e 24dB (Balanced) \/ 18dB (Unbalanced)\u003cbr\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10Hz – 80kHz (+0.5dB)\u003cbr\u003e\u003cstrong\u003eChannel Separation:\u003c\/strong\u003e 80dB (Balanced) \/ 71dB (Unbalanced)\u003cbr\u003e\u003cstrong\u003eSNR:\u003c\/strong\u003e 116dB A-weighted (Balanced) \/ 110dB A-weighted (Unbalanced)\u003cbr\u003e\u003cstrong\u003eTHD:\u003c\/strong\u003e 0.1% (1kHz @ 300Ω)\u003cbr\u003e\u003cstrong\u003eRecommended Headphone Impedance:\u003c\/strong\u003e 60 – 600Ω\u003cbr\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e RCA, 4.4mm Balanced, XLR Balanced\u003cbr\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 6.35mm Single-Ended, 4.4mm Balanced, 4-pin XLR Balanced\u003cbr\u003e\u003cstrong\u003eTubes:\u003c\/strong\u003e 5U4G ×2 (Rectifier) | 12AU7 ×2 (Preamplifier) | 6C19 ×4 (Buffer)\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 330 × 300 × 185mm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 11.0 kg\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e Mainland China\u003c\/p\u003e","brand":"xDuoo","offers":[{"title":"TA-68","offer_id":50486205317359,"sku":"1005012832762723-TA-68","price":1177.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/2004\/1455\/files\/Sfa468797e4f04c70a2a55f8d2d6d521ez.webp?v=1786512556","url":"https:\/\/thehificat.com\/de-de\/products\/xduoo-ta-68","provider":"The HiFi Cat","version":"1.0","type":"link"}
