Description:
This machine is improved and upgraded based on our F1 preamp circuit.
Its layout and materials have been improved. The two channels are independently powered and independently amplified, reducing mutual crosstalk effects. Makes the sound more pure and more accurate. This unit is powered by a Class A power supply, which can ensure that the warmer sound of the original design is fully utilized.
This machine's standard op amp is 4 LME49710NA plastic sealed single op amps (two single op amps are used for each channel to amplify). If you want to upgrade to AD797 / OPA627 and MUSES03, please contact us and pay extra money.
