The NAC 282 is the next level to the 202, the most obvious physical differences being that the balance control is a knob on the front (the 202’s is remote control only) and the record output is selected separately (second row of buttons). But that is not important right now! The real difference is the resolution, refinement, image scale, dynamics, timing, sheer musicality. You might as well get used to this, as the differences between all of the pre-amps are in much the same areas.
It is a good sign when the manufacturer understands their products to this degree (far more the exception than the rule, we can assure you). The Naim upgrade ladder is (mainly) well spaced and the expenditure usually seems quite modest measured against the improvements involved.
Excellent with the 200, 250 and 300 power amps, the 282 can be be powered directly from the 200, from a single Hi-Cap, from two Hi-Caps or a single SuperCap (this last one is well worth considering). As ever, the improvements brought by the upgraded power supplies easily justify the investment. The PSC that transforms the NAC 202 is part of the basic kit, by the way.
