To get the somewhat best out of the 282-200 system, I personally would budget for a HiCap DR. Which makes the comparison, as far as cost, a little lopsided. Even w/o the HC, the 282-200 system is roughly twice the cost of the SN2.
Of course if you budget for a HiCap DR, you should listen to a SN2 with a HiCap, it makes a pretty significant improvement overall, especially with harder to drive speakers. SN2-HC- Ndac price point more or less equals the cost of just the 282-200 combo.
I recently did a home demo of these combinations, and all I can add is that the SN2 sounds more powerful than the 200, that was with a 202 pre. When the HiCap was added to the SN2, another significant jump in sound quality.
By the way, as far as being able to drive your particular speakers, I'm not familiar with them, but the SN2 drives my Dynaudio speakers pretty easily, Dyns are not the easiest speakers to drive cleanly, the SN2 does a superb job. In other words, if the SN2 can't drive your speakers than definitely the 200 will not either. As a matter of fact, if the SN2 is not sufficient then you would need to invest in a 300 to clearly better the SN2 as far as driving difficult speakers.
