The Copland CTA407 amplifier allows you to use any model of the 6550/KT88/KT120/KT150 family as output lamps – the proprietary lossless automatic offset adjustment system will determine the optimal operating mode of the selected lamps. The Copland CTA 407 is supplied with KT88 lamps in the output stages, two 12BH7 dual triodes and one ECC83 dual triode in the pre-amplification stages.

    Like the CSA100 model, CSA150 is built in a hybrid concept. The input amplification stages are implemented on a dual 6922 triode, and the output stages are implemented on high–power MOSFET field-effect transistors. The switching arsenal of the novelty, in addition to three linear unbalanced analog inputs, includes a balanced input on XLR connectors, as well as a phono corrector input capable of working with pickup heads with a movable magnet (MM).

    The 6922 lamp works in the preamp section, and MOSFET transistors matched in pairs work at the output. The device outputs 100 watts per channel to an 8 ohm load, and the power increases to 180 watts when the resistance drops to 4 ohms. The DAC section is built on an ES9018 Sabre chip with support for 32-bit/384 kHz streams and DSD128 when connected to a USB-B port.

    Inside, users will find a DAC and a phono corrector. The first will allow you to connect analog and digital devices, the second — MM cartridges. There is also a headphone amplifier with a 6.35mm jack.
