Z150 MC Phono Input


All prices include plug-ins for both channels.

MusicPower moving coil phono plug-in boards fit all NAC 12/32/42/62/72 series preamps. These boards bring a dramatic improvement in musicality and openness to your LPs. Dual on-board voltage regulators, two for each channel, tighten up the bass and eliminate the boominess of the original Naim NA323 boards. Top quality film and tantalum capacitors at the input, output, and now feedback loop bring an openness and air to all the instruments, and especially to women's voices. The imaging is excellent. There is also an effective RF filter (small ferrite) that eliminates radio break through. This is the upgrade you've been waiting for!

The Z150 boards (replace NA323 K or S) now include on-board compensation jumpers so that you can adjust the settings to optimize the sound quality for your particular cartridge. The resistance range is huge, from 54 ohms to 560 ohms. You can also select either 1nf or 6.8nf capacitance. With this flexibility, you can choose traditional "K" or "S" settings or a huge range of other options. If you have any questions on these compensation values, please email us at If instead you prefer a phone call, please send us your phone number and preferred calling time - we will try our best to respond with a call as soon as possible.

Our MusicPower Z150 plug-ins directly replace the original Naim NA323 boards. Gold plated connectors (identical to Naim's) are used for maximum reliability. Easy installation - absolutely no soldering or rewiring required. (please see the installation manual and/or the video for your unit in the Support section).

Price is for a pair of boards.
