Board level electronics repair shop recommendations?

Folks
Long story short,!I have a topping dx7S DAC/Amp and the USB input on it is non functional. My PC does not even recognize that anything is plugged into the USB port when the DAC is plugged into the PC. The USB DAC section does not even require the unit be powered on. It's probably using USB power for that section. Anyway, I suspect a bad solder on the USB connector or the USB receiver chip, as the rest of the unit works fine ( optical input etc). I was wondering if there are any good mail in repair shops who can work on delicate electronics. Sending it to Topping is not an option as their repair center is in China.
Any repair shop recommendations would be appreciated.
Thanks

I wouldn't bother. If other inputs work just get an external USB to SPDIF converter for about the same amount or less as what you'd pay for the repair, if it is even possible.

On this subject, I recently bought a used DX7s and it is completely broken. Display shows ERR : DAC_R , which probably means the controller unit cannot talk to DAC chips. The seller issued a full refund so that part is good but if you comb through DX7s and other Topping discussions on various resources you'll find enough evidence that their DACs are prone to failure. I'm glad I resisted the temptation to buy expensive gear from them new.
