The Marigo Labs digital cables really allows my 34 MLX to outperform itself. Jerry Ozment, the manufacture recommended this Marigo to me. I am so please I now have 2 spare Marigo cables.
I also own the PS PWT/PWD which are not truly breakin as yet so it is premature for me to voice an opinion compared to my 34.
A 5000-11000 DAC may sound a little better than my 34 but does the price difference justify minuscule improvement.
My 34 is a black box device without military construction and build quality, no NOS tubes, bulk quality coax sockets (which I replaced with WBT and made a tiny improvement), stick on rubber feet, a few leds to tell you the thing is working, no filter or oversampling buttons.
And this goes to show what's inside the box makes my music.
I have been fooled for too long.
