JimH,
Are you looking to pair the IdPi with a UE Boom(pairable for stereo fans), Riva Turbo, Peachtree Deep Blue, or something like the Amazon Echo? Or are you looking to pair the IdPi with kit like a sourced Pi compatible dac, amp module(s), seperate power supply, sourced case, etc.?
Best Regards,
