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 WIMA film 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. In addition, this latest version of the MC boards includes 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) are fitted with replaceable input compensation modules (see yellow modules in the photo) which include a metal film resistor and film capacitor in your choice of values to match your MC cartridge. The Naim "K" boards use 560 ohm/1000pf for many Linn cartridges and WE WILL SHIP YOUR MODULES WITH THESE VALUES UNLESS YOU SPECIFY OTHERWISE IN YOUR "NOTE TO SELLER" WHEN YOU PLACE YOUR ORDER, or YOU MAY EMAIL US AT INFO@RYANSOUNDLAB.COM. Naim "S" boards use 470 ohm/6800pf. Available resistances: 50,100, 220, 330, 390, 470 and 560 ohms. Capacitances: 470pf, 1000pf, 2000, & 6800pf. (Note that a minimum capacitance of 470pf is required for good noise and RFI (radio frequency interference) performance.)

If you have any questions on these module 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).
