To me this is a no brainer. I can not imagine why anyone would pay $2000-3000 for mods to a product (the DCX) that retails for about $300. Unless you have the ability to make the mods yourself and save a bunch of money, you are so much the better to purchase the DEQX.

Among the DEQX capabilities/features (see www.deqx.com) are: Linear phase 3-way digital crossovers with the ability to achieve perfect phase, amplitude, and time matching; Inherent EQ and external tweakable EQ; Room EQ capability to address room integration issues; An easy to use computer interface with supported user group software; A built-in measurement and calibration system so you can see and solve issues that arise; Two digital and two analog inputs with full six channel remote for source selection, digital volume control, and adhoc EQ (DEQX preamp option model).

You will be so much better off with fewer hardware and software issues with the DEQX compared to the modified DCX. I highly recommend the DEQX. I've had mine for nearly five years and with the latest DEQX upgrades (which I think are included in the current production units) it continues to be exceptional. All that for a current price of just over $3000 US.
