Reference one  Mono Block Power Amplifier

Audio Experience Reference One Mono Block Power Amplifier is a Full balanced design power amplifier. It provides sound deep and wide stage, accompanies with reality sound image and a emotions sound presentation.
It uses one matched pair of KT120 power tubes and UL working status to provide 110W adequate output for most of the Hi-End Speakers to ideal performance. Moreover, the high quality output transformer combines with high performance full balanced circuit design lead to an extremely low loss, wide sequence sound effect and excellent phases output. This power amplifier case structure and parts arrangement are perfect, the signal path is directly and shortly connected. Great heat dissipation, an anti-shock and anti-RF function to guarantee it works at a very stable status. For sure, this machine is produced by point-to-point methodology. 



The full balanced input stage is 12AT7  direct coupling to 12AU7 full balanced driver stage , The driver stage use high quality capacitors to KT120 power tube , The KT120 work at P-P mode to driver Tango output transformer , The Tango FC-120-5 output transformer has very low Insertion Loss 0.18dB only.  ( Many tube power amplifier in Hi-End audio market , Their have the output transformers is over 1dB Insertion Loss . only about 10% very high price tube amplifier use under 1dB Insertion Loss of output transformer ) . The output transformer has low insertion loss is very important , the best of the best is 0 dB Insertion Loss , The output transformers for High End tube amplifier need under 1dB  Insertion Loss . The Insertion Loss over 1.5dB output transformer will lost many low level music.

The components ,  NFB value , tube type , circuit all select by listen test.
