High End Preamps
Which preamplifier is best for you? Here are some
|Issue / Feature
||While all preamplifiers sound different, we
have found general similarities among the preamplifiers
made by a single manufacturer. Therefore, we suggest that
you first audition preamplifiers from several different
manufacturers. Perhaps you'll prefer the liquidity and
soundstage presentation of the Audio Research tubed
preamplifiers. Or for example, maybe the high-speed,
high-resolution sound of Spectral preamplifiers will
appeal to you. No product is perfect, and so in your
selection process, you'll naturally gravitate towards
products with the best performance in the areas that are
most important to you. Be sure to listen for tonal
balance, soundstage presentation, transparency, and
dynamics, as well as whichever other performance
characteristics are most important to you.
|Balanced or Single Ended
||Preamplifier inputs and outputs are either
single-ended (with RCA connectors) or balanced (with XLR
connectors). Unless you have very long
interconnects (over 30'), it is suggested that you use whichever type
of cable your manufacturer or dealer recommends. Contrary
to myth, balanced interconnects do not necessarily sound
better. Some preamplifiers are specifically designed for
balanced use (e.g. Audio Research or Boulder),
and sound best with balanced cables. Most others offer
balanced operation, but generally sound best with single
ended cables (e.g. Spectral, Lamm, Classé,
McCormack). Also, single ended interconnects generally
cost less than the equivalent balanced interconnect.
|Tubes or Solid State
||If you have decided that you favor the sonics of a
tubed design, such as Audio Research, you should realize
that any tubed equipment will have somewhat more
maintenance than a solid state design. However, in the
case of preamplifiers, the tubes last a long time (often
about 5000 hours), and are relatively inexpensive to
replace. (Tubes for amplifiers generally last at least
2000 hours, and are more costly to replace.)
If you choose
Audio Research specifically, you are assured of a long
term supply of the necessary tubes. Their designs only
use readily available tubes, and they maintain an
adequate inventory for future service needs. This may not
be the case with other brands.
|Integration with a Home Theater
||The majority of today's stereo preamplifiers can be integrated into a home
theater, if desired. The left and right outputs of the
surround sound processor can be routed through the stereo
preamplifier, and then on to the amplifier and speakers.
In this way, you have a 2 channel stereo system that is
completely independent of your surround sound system.
With today's technology, this is usually the highest
In addition, some stereo
preamplifiers make this even easier. They provide a
special input which bypasses the volume control. This
means that to use the surround system, you merely select
this special input. If your preamplifier does have this,
then you'd also have to adjust the volume to some
prearranged setting (such at 12 o'clock, for example).
||Some preamplifiers have them; some don't. If a remote
control is very important to you, then eliminate
non-remote control preamplifier from your consideration.
If a remote is not vital, then we recommend that you set
this consideration aside as you evaluate designs. You can
then use the remote control capabilities of the
preamplifiers that you are considering as a "tie
breaker" in your selection process.
|Mix and Match Brands or preamp and power amp?
If you have selected a
preamplifier for its sonic merits, you will generally
find similar merits in that same manufacturer's power amplifiers.
However, you may find that another brand of amplifier has
sonic characteristics that you favor. Feel free to
choose whichever brand and model you prefer. The one exception to this
is Spectral, as certain models of Spectral power amp need to be mated
with a Spectral preamp. However any Spectral preamp can drive any brand
of power amp (details). Note that some
amplifiers sound best when used with their balanced
inputs. For these, you'll want to be sure to use a
preamplifier with balanced outputs.

in 1977, Spectral is one of the most respected names in high end audio today.
Notably, to this day Spectral is still run and actively managed by founder
Richard Fryer. He along with head designer Keith Johnson have devoted decades of
their life to bringing Spectral components to a very high level of refinement. Spectral manufactures digital components,
in Sunnyvale, California.
Spectral makes astonishingly transparent, uncolored, detailed,
smooth sounding preamplifiers. With very low output impedance and
stability out to radio frequencies, these preamplifiers are fully
capable of properly driving Spectral's wide-bandwidth power amplifiers.
In addition, you can use a Spectral preamplifier with any other
brand of amplifier and it will drive it with total aplomb. The DMC-30SV line preamplifier is shown here.
