Research is Moving Us Closer
to the Ideal Amp

me AU-X1 is the latest development

in Sansuis ambitious pursuit of the idml amp-the almost mythical "straight
wire with gain." an amp that would provide amplification with absolutely no
adverse sonic eltect on the sound Signal By concentrating our efforts on
eliminating all tranSient distortion. we have. With this supreme model. moved
one step closer to the ideal

In the beginning. we set about improving our amplitiers'
tran5ient characteristics First. we examined the factors that cause transient
distortion Second. wedeveloped methods to measure these tactors. Finally.
we began to deSign new Circuitry based on the results of our research.

What is well known. 0! course. is the very close relationship
between tranSient distortion and the sound quality of today's amps We at
Sansw analyzed tranSient intermodulation (TIM) distortion and envelope
distortion. which we knew would lead to greatly improved transient charac~
teristics ot the AU-Xt In the process. we were able to arrive at the conclusion
that the prevuously held beliet, holding that transient response and steady-
state response couldnt be Simultaneously improved. was erroneous. You
will discover in the AU-Xt that both steady-state and tranSient parameters
are superb By both realizmg the nature ot transient intermodulation. and
by putting to use this knowledge in the AU-Xt. me know that we've come
very close to creating the perfect amplitier The rest ol this presentation tells
you why.
