HOW TO JUDGE A HI FI SYSTEM
(How the Linn TUNE DEM™ helps people to make sound decisions)
The listening procedure that we use to empower customers, and of course that we
use internally at Linn, is called the TUNE DEM™. It involves the simultaneous silent
repetition of the sound from the system. The easier it is to simultaneously make the
same sounds as the system, the more accurate the performance of the system under
evaluation. Most people don't know how to listen actively as opposed to hearing
passively, and are unaware of how to make qualitative judgements about hi-fi
equipment performance. They tend to make quantitative assessments, e.g. prefer
more treble, more bass, more openness, more space, stronger image, more guitar.
Of course the question is not whether you get more of something, which must mean
by definition that you are getting less of something else, but whether you have the
correct amount of everything.
This is not a matter of opinion or personal preference or taste. There is such a thing
as real music. It has indisputable characteristics and undeniable universal
relevance. Silent repetition is what you do when you are listening to someone
speaking and you are intent on gaining a complete understanding. You silently
repeat everything the person says in your own head. This of course is done naturally
and simultaneously without great effort if you are truly interested but requires
deliberate effort if you are not or the content is difficult or important. With live music it
is perfectly easy to reproduce the music simultaneously in one's own head and one
does it unconsciously. This is the mechanism that allows music to communicate the
message of the composer and the listener to assess the merit of the performance as
they are transported by its communicative power.
When the music is amplified or artificially reproduced, especially if it is recorded
music, then there is non-linear alteration to the frequency and amplitude of all the
signal components being reproduced. This distorts the pitch relationships, in other
words it changes the melody or tune. No hi-fi system can perfectly reproduce the
original. The best system is simply more accurate and so consequently easier to
simultaneously silently repeat or sing along with than systems that are less accurate
and may be impossible to sing along to.
It is important to understand that when listening actively you are not meant to try to
sing the sound out loud because you would merely work from your internal musical
reference and use and project it rather than what you hear, to base your
musical judgement. What you should be trying to do is see if you can reproduce
simultaneously and silently inside your own head the actual sounds that are coming
from the loudspeakers. The harder it is to do, the less the sound you are listening to
is like real music, for which everyone has a natural feel and internal reference scale.
With a poor system it is impossible or time-consuming to locate the actual or
approximate pitch of any melodic element and before you have had time to locate
one part of the music and silently reproduce its pitch in your head things have moved
on. The more accurate the system, the easier and quicker it becomes to locate each
individual sound and so this provides the time necessary to track, follow and
simultaneously silently repeat more elements in the melody. The fact that
subsequent elements appear closer to where one would expect helps, as real music
has an intelligible melodic story line and things don't just appear at random.
The music elements, chords and notes are always based on the underlying structure,
the predictable scale that provides the foundation for all music and for which all
humans possess an internal reference coded by our DNA.
The advantage of the TUNE DEM™ is it provides a way to show people how they
can make consistent and quick judgements that will stand the test of time and that
empowers and produces unanimous agreement. If people don't always agree it is
only because they have not actually performed the work and made the effort
necessary to accurately and effectively judge the sound to which they are listening.
If you do nothing you observe nothing and can know nothing. If you don't listen you
won't observe or hear things in a consistent or reliable way. It sounds so simple that
it seems naive yet anyone who tunes a guitar understands what silent repetition is as
you map the external sound of a string being tuned on to the sound you have
previously stored in your head to allow comparison.
People have to learn to grasp hold of the idea that it is what they do that means they
are listening rather than hearing, and that active listening as opposed to passive
hearing involves tracking the sound constantly, and performing the work necessary to
make an accurate observation. The system that is easiest to sing along with when
you are trying to listen actively will have the most communicative power and impact
when you are simply relaxed and hearing and responding without making this effort.
