2.1 DSP sound system. HELP !

Iam from India. here diy audio system is common norm accross youngs. But lot them are analog with some cheap bass treble controller boards paired with a 5200 1943 based ab amplifier circuitry. I tried that same then and found that the amplifier circuit is great but the signal line is the culprit which picks lot of noise no accurate real freq as like the input everything is messed because of the bass treble controller.

I started exploring on some digital signal processors and iam following this man DIY Perks for very long and seen him worked with DSP in his projects. So now iam planning to convert my 2.1 analog system into a dsp based 3 way L R + a subwoofer based 2.1 system.

Imade some digging and found ADAU1701 based DSP board pair could process 8 channels of audio and that fills my requirement. But the problem is i couldnt get one trusted module here in india because it is very costly and no reliable brand name. One thing I could see is from womdom which have some good ratings but it's very costly.

I could see DIY Perks used one from AliExpress and i could afford that but what about its reliablity can anyone help me here ?
