I think you may be misinterpreting a paraphrase of my published statements. If I may, I would edit your interpretation to say: "It seems to me that the user friendliness AND COST of the DIRAC was a major reason Stereophile seemed to RECOMMEND IT OVER the DEQX."
Dirac is cheaper and easier to use but not as capable as DEQX. If DEQX made a multichannel version, I'd use it.
