Searching for an ultra-quiet, ultra-efficient power amplifier with 70-/100-volt compatibility? The Naim CI-NAP 101 should be at the top of your list of prospects. The CI-NAP 101 was tailor-made to complement Focal integrated loudspeakers and subwoofers, plus it can tackle third-party hi-fi speakers and subs with equal aplomb. This rackmountable mono power amp boasts stereo RCA inputs and outputs for trouble-free daisy-chaining, along with dual Euroblock outputs for easy parallel speaker connections. The CI-NAP 101 accommodates both low- and high-impedance setups; its high-impedance outputs sport a selectable highpass filter and are galvanically isolated using toroidal transformers. You also get a music-sensing feature with auto standby and rear-panel Level control. The CI-NAP 101 also includes a universal power supply and a temperature-controlled fan. Here at Sweetwater, we recommend the Naim CI-NAP 101 not only to our Focal 1000 series system customers, but also to anyone with a need for a clean, efficient power amp.
