I owned a stock ART for redbook on my Sony 333ES player. Found it offered slightly more detail. I hummed and hawed over which unit to have modded. In the end I chose to get my Sony "Kerned" and upon its return and without break -in (for those of us who believe in it) it stomped all over the stock ART. The DI/O went down the road in a hurry but I still wonder how a modded DI/O might have performed against the modded Sony. No way to tell now but I'm happy with the choices I made.
My opinion on the DI/O - not too sure its a "giant killer" but even in its stock form its a helluva buy for $130 - don't think you can get that sound for that inexpensive a price anywhere else...
