Phono Preamplifiers

Replacing the longstanding VPS, Nagra's Classic Phono is not only significantly more flexible but its technical and sonic performance also marks an equally significant uplift

Acelebratory cake is in order. Swiss high-end manufacturer Nagra turned 70 last year, and its birthday present to itself is something of a first for the company. That's for another time, but I'm not giving too much away by saying that, when it arrives, it will make the perfect partner to the item under review here – the £17,000 Classic Phono MM/MC phono stage.

Joining Nagra’s monoblock power amps, preamp and DAC X separates in its HD (High Definition) line, the two-box HD Phono channels the brand’s 70+ year audio heritage

With the HD Phono, Nagra has joined a rather select group. By my estimation, there are but a half-dozen manufacturers of phono stages costing above £50,000. At a heady £68,500, the all-valve Nagra HD Phono is about as expensive and exclusive as it gets, and for that amount of money you expect to get everything. And you do.

Dutch tube aficionado, PrimaLuna, has offered an optional solid-state phono module with its amps for years, but now comes its first standalone, all-tube MM/MC preamp

With vinyl sales now surpassing CD, the revival is back with such force that the flood of phono stages and decks will surely continue unabated. More than that, it's enough for PrimaLuna to show its confidence in analogue to bring out its first EVO phono amp, the EVO 100 Tube Phono Preamplifier at £3398.

Primare's 'Prisma push' may have focused resources into network-enabling its amplifiers and CD players, but its new flagship phono pre proves its love of vinyl has not waned

Even the most ardent vinyl enthusiasts will admit that they can get bamboozled by the whole process of cartridge loading and gain matching. Some MMs and MCs can be quite particular about the load resistance and capacitance that they 'see', just as most phono stages will have a 'sweet spot' gain setting that varies from pick-up to pick-up. So there's a great deal to be said for a flexible phono stage that offers numerous adjustments. On the other hand I can appreciate the popularity of designs where the complexity extends to nothing more than an MM/MC switch!

Moving-coil pick-ups are inherently 'balanced' and Pro-Ject is determined to reveal them at their best with this balanced-wired version of the X2 deck and phono preamp

One burning question is begged by the arrival of Pro-Ject's X2 B turntable and Phono Box S3 B phono stage: why did it take so long for the industry to simplify a balanced vinyl-playing front-end? It's not like balanced operation wasn't adopted by high-end listeners decades ago as superior to single-ended for both line-level sources – DACs and top-flight CD players – and pre-to-power amp connections. MC cartridges are inherently balanced. So why the wait?

While there’s little that’s grand looking about RCM Audio’s Sensor Prelude phono amplifier, despite it costing considerably in excess of a grand, close inspection reveals that it has been purposefully designed. A substantial brushed alloy fascia disguises what is otherwise a rather utilitarian metal case. But there’s little to complain about its construction quality, other than the cheapness of the stuck-on rubber feet. A separate power supply box connects via an umbilical cable of fixed length and locking DIN connector while the cable is generous in length to allow remote placement.
