Sabai, No experience with the Qx4.I did however own 3 of the Quantum Symphony Pro units that were made from the same company that now makes the module for the Nordost unit.
I thought it improved video quite nicely. With audio they seemed to create a suck out in the mid bass range so I sold them. Perhaps the newer Nordost units have improved on this.
Also, on the internet I saw the insides of the Nordost units, and I could'nt believe that there is close to nothing inside!
I realy don't know if the Audio Magic PEA's and the Nordost units are similiar in function, you would have to ask Jerry.
