This may be a dum question but why would you need bluetooth ? My active speakers have Bluetooth!

Simply because my passive speakers don't.

Can these tube preamps be connected to power amplifiers , phono and headphone mini tube preamps ?

Hi Hollis, you ask about Box X3. My Fosi is a Box X2 bought in 2021. Let me tell you about my product. My INPUTS : MOVING MAGNET turntable (phono) 3.5 mm AUXILIARY (headphone) 12VDC My OUTPUT : RCA interphase to AMPLIFIER or ACTIVE SPEAKERS Being more modern X3 should have same configuration plus extras, e.g. bluetooth. To answer your question : yes, you should be able to connect your X3 to power amps (or preamps), phono stages and headphone preamps. My advise to you is to download the user manual from the FOSI AUDIO site and recheck. Good luck.

Fosi, be the first to produce a mini tube preamp that includes phono, bt and aux inputs plus a remote control. why not ?

It didn't work at all; no sound came out except a hum.
