Lindsay, I have been listening to the NAC 202 / Hicap DR / NAP 250 DR and Dalis for four days now. Listening sessions were varied. On a good day it's approximately 9 hours.
Chris, when I received the NAP 282 (prior to receiving the NAP 250 DR's shipment), I have briefly tried the Dali Mentor Menuets with the NAC 282 / PSU from Israel / NAP 200. At that time I did not have the Hicap DR and the Chord QBD76 with me yet. I didn't do any serious listening with the NAC 282 / PSU from Israel / NAP 200 as my focus was on the Harbeth at that time, not the Dali. Having said that, the illuminating character of the NAC 282 is quite apparent even with the Dalis.
Another way to describe the NAC 282 is it sounds like a tube version of the NAC 202 which gives it the illuminating sound. Not the warm, lazy or cosy tube-like sound but one that's dynamic, punchy and illuminating.
