In the Naim range a good match would be NDX2/XPSDR. A bare NDX2 would work, but without the power supply upgrade it’s not really at the same standard as the 282/250. Alternatively go for an ND5XS2 and a DAC upgrade from Naim, Chord, or whatever other brand appeals.
Another option to consider would be an NSS333.
Presumably you are aware that the 282/250 will require a Hicap to work, unlike your 202/200 for which it was optional.
