Just magnificent
This is superb, the sound output is clean and distortion free, just make sure you have a high gain pre amp as it lowers the output by a bit.

Can be better 😄,also over priced
I change the capacitors 224J100 to 100nf (104kA) for bass which gives me good bass if you want more deep bass you can replace these cap. To 127nf (25 hz ~) , For treble lovers replace the 233J100 to 220pF ( 14-16Khz) , i am currently replaced with 104 pF over the product is good after some modifications , it also reduced the volume 20-30% so,use the preamp module.

Good preamp, but low volume output
Preamp filters bass & treble well. However, the output volume is low, tried it with a few different amplifiers, with similar results. Basically, its sound quality over quantity. Active preamps are better for loud volumes.
