No sneering Please

I am impressed too...I own two very low cost pre-amp S.S.  Fosi sk01 and  tube Douk P2 , neither is junk ...Not hi-fi for sure ,  but not junk ...😊

For me there is 2 simultaneous revolution in audio , low cost producy at relatively high quality which never existed before in so large numbers ... And the BACCH filters ...

I have a couple Fosi amps including v3. Color me impressed. One drives a pair of KEF ls50s very nicely. Audio Science Review site has done reviews of many affordable amps like these and is a good resource for more info.

They cannot all describe my optimized AKG K340 if they did not own it ...😊

 Happy Christmas to you and your family ...

The only kind of review that I trust says something like, "... made the singers on my records sound more like people I have heard live."

Not many say that.

I believe only many reviews not one or two, but many , reading between line ...
