Here is a new one from the clever marketers at Schitt Audio taking a reject pile or leftover PCB boards and selling them to Schitt fans as coasters.

I would a clean simple switching(no volume control or power circuits) box where I can feed my RCA out from DX7S DAC into a box with 2 or 3 RCA outputs for 2 different amps.
Like something small but well built and doesn't any noise to the signal .
Thanks
