Primare R32 Phono Preamplifier Review

I have been lucky enough to have a brand new Primare R32 Phono Preamplifier on loan to audition over the last few weeks and I wanted to share my experiences, by writing a proper review.

The Primare R32 phono preamplifier is designed in Sweden and is a fully discrete, solid-state, DC-coupled, class-A phono preamplifier. The R32 has three gain settings, allowing it to work with the vast majority of cartridges available, past and present.

The R32 features very convenient externally switchable resistive loading for your moving coil cartridges. The input can be adjusted between 10 ohms and 47 kohms, with a broad range of steps in between. This allows owners the freedom to explore the subtle and not-so-subtle changes one can make to the sound of a MC cart, by varying the resistive loading.

In addition, there are two external gain settings, for MM and MC cartridges. The gain is a good 40 decibels in the MM operation (internally, you can switch to 46 decibels). There is a 62 dB gain available for MC signals and that is enough for the most current pickups.

Load impedance knobs and gain selector switch, flanked by gold-plated Teflon-insulated RCA sockets – very nice!
A clearer view of the configuration options on the rear panel of the R32. This sort of ease of set-up makes the R32 a winner already.

Being a discrete design, there are only a few transistors in the signal path and no chips. There is a DC servo, implemented with feedback by an op amp, but this lies outside the signal path. To clarify, really everything is in the signal path, but the DC servo essentially lies to one side of the signal path and acts to correct any DC voltages that might make their way to the output.

DC-coupling means that the frequency response of the Primare R32 phono preamplifier is ruler-flat down to a few tenths of a Hertz, almost guaranteeing excellent bass performance. The R32 certainly doesn’t disappoint, bass is taught, tuneful and powerful, as good as I have heard at this sensible price-point.

The cassis is gorgeous too, I almost forgot to mention this being blow away as I was by the sonic performance! You can do better of course, but for me that meant swapping back in my Fidelity Research XF-1 step-up transformer and using the Primare as a moving magnet gain stage. Adding in the FR transformer and taking away a bunch of transistors added air and ambiance to the sound, without changing it tonally. You really can’t do better than by using a premium Fidelity Research transformer if you have a moving coil cartridge.

 

So, overall, the Primare R32 is an excellent phono preamplifier. It smokes the Cambridge Audio 651P I auditioned recently and is a class act, at around AUD$1000. Bass is deep and taught, midrange more fluid than lesser phono preamps and the treble, smoother and airier. The R32 punches up at the top of its class. It’s smooth, powerful, extended, never fatiguing and you can always upgrade it by adding a transformer later. The Primare R32 is highly recommended!
