1. Take a 990 and any other processor of any manufacturer at any price.
2. Set them up to operate the same amplifier and speakers in the same room.
3. Set levels between the two units to within .1db.
4. Set up all listening modes in both products to have the same parameters.
5. Listen to both for as long as you want to any musical material and source you want in any and all modes
6. The key factor is that you may NOT know to which processor you are listening. An ABX comparator or a willing, close-mouthed friend are two ways of accomplishing this.

Prediction: Not one of you will be able to tell which is the expensive brand and which is the Outlaw. If the test were done double-blind, you would not be able to discern if you were listening to the same or different processors much less opine on which is "better." For example, read the results of years of blind testing performed by Peter Aczel.

Outlaw, why don't you set up such a test?
