Part of Sonys last series of High-End units, specifically designed for the SACD format and the SCD-1 flagship - all with outer-space bandwidth requirements. As for the xxx-rare R10 units, no expense was spared for the 1 mini series. High-bandwidth oblige, the star of the show is the Phase Linear Amplifier, allowing phase to remain linear up to 100Khz, with only 5dB attenuation around the 100MHz region ! The chassis of the TA-E1 is a sandwich of 1cm aluminium and 2x 2mm copper plates ; the top plate is 7mm thick, enlarged to 10mm for the front and back parts. Power supply and rectification are set in a separate enclosure, very much like the pre-Esprit preamplifiers :) The attenuator has a 5cm diameter and allows channel balance error of only 0,5dB between 0dB and -100dB ; depth is of 9,5cm while the structure of it is full oxygen-free copper made under hot casting conditions. Ultra-low resistance plastic is used. The power transformer is amorphic and toroidal with ultra-magnetic materials (nickel, cobalt and iron) used for the metal core and precise winding arrangement ; it is housed in a ceramic box for optimal damping and avoidance of any possible flux leaks. The four die-cast Metal Core Modules hold the input/output stages PCBs and are used as heatsinks as well (decoupling the boards from the chassis along the way) and as components are surface mounted, shortening signals paths as well.
