Phono Preamplifiers

Bavaria-based Lindemann is perhaps best known as a purveyor of audio products aimed at the high-end hi-fi sector, but to mark its 25 years in business the company has launched a series of more affordable components. The Limetree range uses the same 120 x 120mm form factor and the moving-magnet and moving-coil phono stage is the first to be released in the UK through distributor Elite Audio. We’re told that a USB DAC, headphone amplifier and streamer components will follow in due course.

Getting a valve phono stage to work well is no easy task when you bear in mind that on the quieter parts of a record, the output from a moving coil cartridge may only be about a millionth of a volt. This needs to be amplified up to a standard line-level output of around 1. 2Vrms, so for a start the whole circuit and power supply needs to be as quiet as a mouse. Then the stage itself also has to be first rate and stable under all operating conditions.

The final frontier Primare's beautifully built, full-width phono stage is the perfect partner for serious vinyl systems says analogue addict Jason Kennedy Primare’s new R32 has got to be the biggest phono stage on the market for under a grand, In fact, you could fit a dozen Dynavector P75 MkII stages inside it! Size is not usually considered a bonus in such devices but it has two benefits: you get a component that matches the rest on your rack and it’s extremely well built. You also get plenty of space between the power supply and the internal circuitry. When you are amplifying the pitiful output of a moving coil cartridge you need the quietest environment you can get and this is one way of achieving it. Back in black In 2009, we reviewed Primare’s R20 phono stage (HFC 320), which was half the width of the R32 and nearly half the price, but had the unusual feature of variable gain for the MM input only.
