The new Musical Fidelity Primo, zero feedback, pure Class A, triode, fully balanced preamp. Superlative sounding, beautifully built, beautifully designed, extremely reliable. This Preamp is the best, most exotic high performance preamp that we know how to make. Having zero feedback, pure Class A triode, fully balanced design with superlative technical performance. Considering there is 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 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. Sound quality. Sound quality is always difficult to talk about because its a matter of opinion. The immediate impression of the Primos 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. The bottom end is very extended and fast. Design and build. We have spared expense or effort to make it as beautiful and well made as possible. The front panel is machined from solid milspec aluminium billet. It's badges are made from medical grade stainless steel. The top and sides are machined from solid aluminium and finished to a high standard. We've tried our best to make the unit not only beautiful but also timeless. Even the remote control is extra special. It is machined from a solid billet of aluminium. All the push buttons are also turned from solid aluminium. The price! is not cheap but there again it isn't crazily expensive. It is the best preamp that we at Musical Fidelity know how to make. Even if you're never going to buy one we suggest that you have a good listen it's really special.
