You don't need the Box X2 at all. On the Sony turntable, you turn off the preamplifier (which is built-in) and connect it to the Phono input on the Pioneer. If you still want to use the Box X2, then on the Sony, turn off the preamplifier, connect the Box X2 with an RCA cable, and from the Box...

As far as I know, there is no bluetooth device that can transfer the output signal from the amplifier to passive speakers, because it is about high amperage currents. You can only get another stereo amplifier for those speakers and use the purchased Bluetooth device as an input signal for that...

What is your complete audio chain from source to speakers, excluding the CD player? MC331 is not a DAC, it is a speaker amplifier that also contains a DAC and cannot be used as a standalone DAC.

You didn't mention that you also have a Denon receiver. Where are your speakers connected - to the MC331 or to the Denon? You don't get anything with a coaxial connection between the MC and the Denon because both devices have coaxial inputs (the MC doesn't have a digital output). Can you explain...

It would help to know which CD player it is. To connect to the MC331, you can either use a digital connection via the coaxial output, in which case the DAC in the amplifier is used, or an analog connection via the RCA connectors, in which case the DAC in the CD player is used. There is no need...

Why did you use simultaneously digital and analogue connection between CD player and MC331?

I definitely wouldn't dare to leave a bad power supply constantly on in an unobserved place - it could cause a fire in the worst case.

Do you turn off just the amp or do you turn off the power supply as well? If you do not turn off the power supply, then it always remains under voltage and heats up unnecessarily, which shortens its life.

From Fosi amp Pre Out (3.5mm TRS) to Kurbis aux in (3.5mm TRS) or PC in (2 x RCA).

No, 3.5mm output is analog, but COAX input is for digital signal.

Fosi Audio is in China, not in the US.:oops:

I don't think the connector will fit because the internal dimension is smaller than the one on the amplifier. If you can change the connector for a suitable one, then that adapter can be used.

I don't think there is an option for remote control.

When you turn the volume pot fully clockwise, the output contacts are short-circuited and the quality of the pot itself is not affected. If you are skilled with a soldering iron, you can also bridge the pot with jumpers.
