The GoldenEar Triton Reference
{:6_130:}
The I/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally simple, visually engaging, and musically sublime - the I/50 takes music listening to a whole new experience. Hand-crafted in Minnesota, the I/50 is built with the same attention to detail as all other Audio Research products - each one even gets its own listening test with sonic designer, Warren Gehl. Available in six colors, the I/50 features Cerakote finishes for a beautiful and long-lasting look. The modular design allows for the installation of two audio modules - a Phono Stage, and a D/A Converter (to come in 2022). The high current, 50 watt per channel amplifier is capable of driving a wide variety of speakers. A headphone jack allows for personal listening time.
The I/50 is designed to be easy to use, and has three controls on its top panel - Power, Input, and Volume. Two LexieTubes® provide display information for input selection and volume. Two matched pairs of 6550WE vacuum tubes, along with three 6922 tubes, stand in front of the perforated transformer cover. Three single-ended inputs and one XLR input provide connectivity for most systems, along with 4- and 8- Ohm speaker taps to accommodate your speaker of choice. One input can be assigned for pass-through function. A full-function metal remote control provides further functionality and operation. An optional tube cage will be available.
As with all Audio Research products, the I/50 is built entirely in our Minnesota facility by a team of skilled technicians and expert craftspeople. Offered in six colors, the I/50 is the first product completely finished in-house. The Audio Research finishing lab encompasses a purpose-built painting facility and laser imaging and marking machines to produce a luxurious finish normally found only on much more expensive products. The Cerakote finish is not only beautiful, but designed to be enduring and easy to maintain.
The performance of the I/50 belies its compact design. 50 watts of all-vacuum tube power energize your speakers with beautiful and lifelike music. Designed by the Audio Research engineering team and fine-tuned by Warren Gehl, the I/50 has been given the same level of care and attention as our Reference Series products. The ability of the I/50 to reconstruct a musical experience will thrill and excite all who hear it. Thanks to the substantial power supply and high current design, the I/50 provides controlled and dynamic playback - even on challenging speakers.The Phono module provides 42 dB of gain, allowing a wide choice of moving magnet and high-output moving coil cartridges. The D/A Converter will have multiple connection options and an array of decoding formats to accommodate the wide spectrum of music formats and resolutions. The I/50 is a truly integrated product while providing renowned Audio Research performance and sound quality.

AMG-STA 高階技術下放
NuPrime STA-9X 後級擴大機
STA-9X 是 NuPrime 頗受好評的 STA-9 立體聲後級的後續版本，除了由原先的 ULCAM 超線性 A 類模組 + D 類放大設計的基礎進行改進外，更加入了得自 AMG-STA 後級的先進技術，讓 STA-9X 的聲音不僅更為溫暖厚實，而且兼具更好的清晰度與速度感，可說是大幅提升。
STA-9X 最大的變革是在訊號前級放大階段，加入一個高阻抗的單端負迴授放大電路，再搭配上雙負迴授 D 類放大電路，可使細節表現和解析力更為優異，整體性能較前代大幅提升。此外，STA-9X 除了輸出功率從 120 瓦提升至 130 瓦，輸出電流的能力也比前代提升 130 %，面對低阻抗喇叭有更好的動態與控制力。STA-9X 還採用了新設計的電源，搭配訂製的高效率環型變壓器，可降低高頻噪訊並提升低頻性能表現。
在 8 歐姆負載下，STA-9X 具有立體聲 130 瓦輸出功率，峰值功率 170 瓦，或是橋接成單聲道機種使用，這時功率可提升至 330 瓦，使用上更具彈性。
