Consonance T1 tube pre-amplifier

T1 is a no compromise all-vacuum-tube line stage pre-amplifier designed for any high quality stereo power amplifiers. It uses Shuguang5Z4P/GZ34tube rectifier with choke and Philips electrolytic capacitors (audio grade) in the power stage for pure DC filtering. The amplifier circuit uses four JAN Philips US military grade 5814A (12AU7/ECC82). First pair is directly coupled using well-improved SRPP circuit and the second pair is acting as zero-gain buffer giving a low output impedance for better matching with power amplifiers. T1 uses no global negative feedback offering excellent musical dynamics, impressive sonic transparency and huge sound stage. A special feature almost unheard of for tube pre-amplifiers at this price level.
