NAC 152 XS is Naim’s entry level pre-amp. Intended to be used in concert with the 155XS power. With the Nait XS being such a serious performer, the NAC152 needs to be good.
Thankfully, it is. Unlike its predecessors, it can be upgraded with power supplies on both the audio and control electronics side. The Flatcap has two channels of supply and can do both jobs simultaneously. If you are looking more of what the Nait XS does well (and with more wallop), then the 152/155 combo is for you. Probably the best value in the Naim range.
