Anyone tested maybe useing Pluto -P board + Mesa 7i33 ? Pin out would match each other . I am only in doubt about output ripple , because Pluto works on 20kHz PWM rate.
The 7I33 would have significant ripple (say 50 mv) at 20 KHz because it only has 2 pole filtering (its really designed for PDM which has better ripple characteristics)
Unless you already have the Pluto-P, and it is working on your specific parallel port, then I would suggest not using a Pluto-P.
The chap who wrote the driver couldn't make it work dependably on all machines, and if he couldn't, who could?
