Hi Ali
I do not know the products you name exactly.
But: Theta sounds good to me and I've heard very nice D/A converters of this brand.
I don't see Sony as a high end brand really. On the other hand I tested an old 555 once as a drive and the result was quite good.
The Sony could be the better drive than your Denon but I would nevertheless recommend to look for something else.
