You’ll hear a lot of talk about harmonic distor tion, but odd order harmonic distor tion is what really
compr omis e s yo ur s ound . T he R y val a mp fea tu res dual dif fere nt ial t op olo gy a nd a symme tr i cal
voltage drive stage, designed to improve power supply noise rejection and reduce distortion on all
levels. I t costs us more to build an amp this way, but it makes for bet ter sound qualit y.
TO R T U R E T E S T E D
Our equipment has to per form in any environment. So we’ve devised methods of qualit y assurance
which consist of put ting our amps and speaker s through conditions we couldn’t sur vive ourselves.
When t hey c an run for t wo week s at full power 24 / 7 in an environment al chamber cycled from
14 degrees to 131 degrees Fahrenheit, sur vive shock tes ting, brutal vibr ations and a bat ter y of
endurance testing, only then do they get our stamp of approval.
SOUND BITE TRICKS OF THE TRADE
QUALITY PERFORMANCE? HERE’S WHAT SOUND SPECS ARE (OR AREN’T) TELLING YOU
POWER HANDLING: RMS VS MAX
This testing option will tell you
whether the specs you’re looking
at will really get you the power
they promise. R MS, or R oot Mean
Square, means that the power was
tested at a continuous level — one
that your system could sustain.
MA X is the number obt ained by
running the system to the highest
possible capacity — something that
no system could maintain.
CE A METHOD
CE A —the C onsumer Elect ronics
Association—sets st andards for
per formance tes ting. This tells
you t hat the number s listed CE A
were obtained with rea sonable -use
testing practices.

Audio companies spend a lot of
money to mar ket their pr oduct s
(we’re doing it right now ) . So
if they’re N OT mentioning a
par ticular number in testing, it
probably means they don’t want
you to k now what it is. M ost
people can’t hear T HD at les s
than 1% . But some test s provide
per formance numbers with a
TH D so high you’d never listen to
it—they just don’t lis t the T HD.
