valve amplification system is not only one

of the finest sounding pre/power valve amplification

combinations available today, it is an aesthetic and engineering

masterpiece.

An understated elegance lies beneath the smooth curves and

lustrous finish, for the power amplifiers use a circuit dating back

over fifty years to the time when vacuum tubes ruled the

electronics industry and Peter Walker was the master of audiophile

design. He often shunned traditional thinking, preferring to go his

own way, relying on excellence in circuit design. Circuits that are

still admired today by the finest minds in electronics for their

stunning performance and, by today’s standards, simplicity.

T

nlike the power amplifiers, the Quad Control unit utilises a completely new circuit design. Once

again, the circuit is simple in concept yet remarkable in execution. Our designers scoured the

globe for the very finest components, with possibly the best example of this being the new ‘old stock’

6111WA double triode. Designed as a special military valve, it is hard wired to the circuit and has an

estimated life of nearly 100,000 hours. Together with transformers designed by one of the World’s leading

authorities and relay input switching, the musical signal is preserved in its purest form, all pursuant to the

philosophy of the perfect amplifier which, as Peter Walker himself stated, is ‘a straight wire with gain’.
