Copland CTA 305

For low level voltage amplification, valves are in a league of their own with respect to linearity and musicality.
For nearly a decade, COPLAND has contributed to the refinement of amplification using these classic devices. The CTA 305 employs reliable E83CC valves selected after ageing to assure optimal compability.

Each class A line level amplifier circuit is divided into two separated non inverting units. This allows us to use a much less complex circuit, with increased stability, and no requirement for internal compensating networks.
Discrete DC power supply regulates designed for nearly zero output impedance isolate individual gain stages from each other.

In addition to the five sets of line-level inputs, the CTA 305 offers a high quality phono level amplifier. For the listener with a large investment in LP's, this amplifier provides an opportunity to recover musical pleasures and more nuances from irreplaceable recordings.
