Audiozen, the DacMagic contains 2x wolfsen chips. One for each of it's 2 channels. The BD-751 contains 5x wolsen chips. One for each of it's five channels (you will only be using 2 for stereo).
The DacMagic uses ATF upsampling tehchology licensed from Anagram Technologies, which has now been renamed as 'Q5 upsampling'. Same thing in the BD751.
So you can see, the sonic signature of these devices will be much the same due to the use of common components and design.
DacMagic has the sonic advantage of a dedicated enclosure and power supply not shared with an optical player. And it also has the convenience of multiple digital inputs.
