Tuners - analogue or digital - are tough to design. The trio of tuners that mastered all of the technical
issues during the pre-digital era, with to-die-for sound quality thrown in, consisted of the 1964 Marantz
10B, McIntosh’s MR78, which arrived in 1972, and the Sequerra Model 1 of 1973.
It’s no coincidence that the last of these milestone tuners bore the name “Sequerra”, as Richard Sequerra
was credited with co-designing the previous decade’s champion, the Marantz 10B, along with the
deservedly-celebrated Sid Smith. Indeed, when the Sequerra Model 1 first appeared, it was billed by many
as “a solid-state version of a 10B,” an instantly comprehensible way of describing it as the Marantz 10B’s
logical successor. For the next 15 years, the Sequerra Model 1 ruled as undisputed king-of-the-hill, only to
be dethroned by the next Sequerra. This time though it was a DaySequerra, launched in 1987 and
designed from the ground up by newcomer David Day. As one with experience of both, trust me on this:
no matter how good your 10B or Sequerra Model 1 – and they’re still breathtakingly good – they cannot
offer the silent, noise-free background, the frighteningly quick transient attack, the dazzling transparency
or the near-perfect drift-free tuning of the DaySequerra. As Larry Greenhill stated in Stereophile’s
Recommended Components the A-rated DaySequerra FM Reference “Redefines the state of the art in
FM tuners' with respect to its tuning ability, FM signal display, and sound quality." And he’s right: it still i
the reference.
Now David and his team have produced a new line of DaySequerra tuners for the 21st Century. And
they’re doing this at the most turbulent time in radio's history, just as the very means of broadcasting is
changing. If these new tuners are anything at all like their predecessors, then we’re in for something
incredible - awesome radio. Count me among those eager to get hold of David’s new breakthrough
designs. I mean, we just can’t let the iPod have the future of music all its own way, can we?
