Audio Note SORO SE review

Audio Note SORO SE just arrived at Mono and Stereo Denmark office. This is going to be a world first review of a tube amplifier done in five sections, with a full insight of how the amplifier performs as it goes through a 5 stepped upgrade.
First stock SORO SE. Second SORO with kaisei power supply upgrade. Third a SORO with upgraded line stage, done with the new audio note 2 watts resistors and filter caps. Fourth a SORO with upgraded power amp section along with new 2 watts resistors. Fifth SORO finally completed with all silver wires, silver sockets, better output transformers and potentiometer.
Stay tuned for this awesome insight in Audio Notes upgrade path.
