Musical Fidelity Primo

The Primo Preamp is the best, most exotic high performance preamp that we know how to make. We have been developing the Primo for the last twelve years.

The Primo is a zero feedback, pure Class A triode, fully balanced design with superlative technical performance.

Considering that the Primo has no overall feedback its distortion is low at 0.0035% from 10Hz to 50kHz. Its noise ratio of -119dBA is equally exceptional.  And then you realize this is done with tubes and zero feedback. It’s quite something.

The Primo’s 14 tubes are not just for show. As a result it achieves remarkable technical performance. There is a striking consistency between all Primos. The audible effects of tube ageing are dramatically reduced and tube life greatly increased.

We’ve tried our best to make the best preamp possible and that is the Primo.

Sound quality.

Sound quality is always difficult to talk about because it’s a matter of opinion. The immediate impression of the Primo’s sound is a free, open quality with a huge, wide, deep image. The music seems to come from a black velvet background and dynamics are delivered incredibly quickly. More important, perhaps, there’s no overhang after dynamics. They’re there and then they’ve gone.

In a way small dynamics convey more of a sense of reality than big slam ones. The Primo excels in this area. Coupled with the exquisite sweet sound is the sense of speed and instantaneous realism that marks out true high end.
