Mô tả
A19 là sự lựa chọn hoàn hảo cho các khách hàng đang tìm kiếm một chiếc ampli có thể tái tạo âm thanh đặc biệt nhưng giá cả lại phải chăng.
Featuring some of the latest thinking in high performance amplifier design, the A19 uses components and techniques mormally found in Arcam’s top of the range products. The amplifier’s design and performance have been refined and tuned to an exquisite degree. This focus on sound quality has led to an intellegent power supply design that also enables the amplifier to offer a flexible upgrade path. The power section of the A19 is design to be able to supply two of Arcam’s class-leading r-Series products in addition to its main duties. This allows the A19 to become a digital hub for a whole range of digital connection upgrades that includes both wireless Bluetooth® devices and USB sources.
While the world of music is increasingly a digital one, analogue sources are not forgotten. The continued popularity of vinyl has led Arcam to to equip the A19 with a new ultra-low noise moving magnet (MM) phono stage that allows the music enthusiast to enjoy their vinyl collection afresh. While the use of high performance headphones has grown dramatically of late, little effort has been made to improve the headphone sections of the amplifiers that drive them. The A19 addresses this by employing a completely new circuit that can deliver a level of sound quality that will thrill even the most demanding listener.
