I have factory DSP too. I bought the Avant4 with the optional Advanced DSP Sound Processor Chipset with 15 EQ Band - I guess that was a waste of my $30. I can only hear the hissing sound when nothing is playing and I turn up the volume, otherwise no other background noise (or it is drowned by regular audio).
