How do I connect the stack to audio speakers correctly?

[keygeen]

Good time of day. Please tell me how best to connect the Airpulse A300 pro stereo pair to my stack. Stack Topping D90SE\A90D. Is it possible to connect the A300 XLR to the A90D (already connected by XLR balance to the DAC)?
Or do I need to change the circuit by reconnecting the stack via RCA to each other, and the A300 to the D90SE via XLR?

Hi @keygeen! Welcome to ASR.

The A300 Pro is best connected to your Topping stack like this:
D90SE XLR Line out->A90D XLR Line in->A90D XLR Line out->A300 Pro XLR Line in.

In case the A300 Pro uses a digital crossover, you would get higher fidelity by connecting it to your computer via Coax, Toslink, or USB, bypassing your Topping stack completely.

Reading the user manual, this seems to be the case, so I recommend doing that.
