hfnvintageWith VFETs costing top dollar and facing stiff competition from other semiconductors, the late '70s saw Yamaha unveil a new pre/power amp duo. How does it sound today?

It's always intriguing to see how a company reacts to the realisation that a technology it has championed is reaching its sell-by date. This was the situation faced by Yamaha in the late 1970s. Since the middle of that decade, its top-end products had made use of Jun-ichi Nishizawa's Static Induction Transistor – more commonly known as the VFET – to great effect. This led to the development of designs such as the B-1 and B-2 power amplifiers, and C-1 preamplifier, all of which are still held in high regard.

Talk to audiophiles that grew up through the 1990s and the chances are they associate brands such as Sony, Yamaha, Onkyo, Pioneer and Denon with meaty AV receivers and, possibly, mini systems. The reason is that it was around this time that the major Japanese corporations began directing their energies into developing products for the burgeoning home cinema market, meaning these younger hi-fi enthusiasts never really saw them flex their design muscles in the stereo arena.

hfncommended.pngCombining simplicity with flexibility, this pre/power combination from one of the best-known names in French hi-fi has much to offer – including the odd quirky feature...

Like some other French audio companies, Yves-Bernard André's eponymous brand has hovered on the periphery of UK hi-fi enthusiasts' perception. But the company has been on a mission to change all that, taking a more global view with a lineup extending to no fewer than five product ranges. The Passion models, represented here by the £6750 PRE550A preamp and £5750 AMP650 power amp, sit near the top of the pile.
