NOW AVAILABLE FOR THE SONY SCD-XA5400ES PLAYER!
Modification of the
popular Sony SACD players for improvement of their
already very good musical sound quality has become a
booming cottage industry. Small wonder, because these
upgrades generally offer extremely significant, cost
effective benefits that most listeners can readily
discern and appreciate.
Typical changes include substituting a low-jitter clock
for the cheap crystal used by the manufacturer,
sometimes accompanied by new power supply circuits for
the clock, and often substitution of higher quality
resistors, capacitors and connectors, in the signal path.
Good, although the preceding steps are, our esteemed
associate Allen Wright of Vacuum State GmbH, Inc. was
convinced that more was needed to completely unlock the
enormous potential of this new ultra high resolution
Sony/Phillips Direct Stream Digital (DSD)/Super Audio
Allen went to work on the problem and quickly learned
that when the high frequency response was allowed to
continue to 100kHz (instead of Sony's conservative
60kHz), things came alive with more air and space around
the instruments and voices.
And then, perhaps even more important, is the removal of
the opamps, which the other mods leave unchanged. The
typical Sony player includes four (yes, 4!) opamps per
channel, each with a copious amount of transient
intermodulation distortion, "covered up" by
lots of time-smearing negative feedback, in the analog
signal path. These constitute Sony's filter/buffer stage.
This function is essential in a SACD player, but can be
performed just as effectively without resorting to
sound-quality degrading opamps.
A completely new high frequency filter/buffer amp,
attenuates the unwanted ultrasonic noise from the
DSD/SACD process, so that downstream amplifier stages
will avoid being "confused" by these signal
Replacing the opamps and their mass of associated
capacitors and resistors entirely, this brand new Vacuum
State single stage, filter/buffer amplifier is designed
around low noise audio specific diamond transistor arrays,
with all components, active and passive, carefully
selected for top sound quality.
No changes are made to the
Sony analog audio section - it is simply not used.
To take full advantage of the new audio output stage, the
Vacuum State mod now incoroprates the incomparable new
Terra Firma Lite clock system for exquisite lifelike realism.
The sound? We thought we had "died and gone to Hi-Fi
heaven." We consider it to at least equal all but the most
costly analog front ends. And we seriously doubt that
many people have analog equipment that sounds as good as
Vacuum State modified Sony SACD players.
We are sufficiently confident that you will be satisfied
with this stellar sounding mod, that we will perform the
service almost entirely at our risk. After having
listened to your modified player for up to 30 days, if
you should prefer to have the mod reversed, simply return
the player to us. We shall then remove the new parts and
restore the player to its original configuration and
refund the full parts and labor purchase price, except
the shipping and handling charge.
Redbook CD (RBCD) reproduction also in enhanced greatly
by the Vacuum State mods. Listeners have commented that
redbook, through the mod, sounds as good, or almost as
good as SACD, without the mod.
The price of the mod with Terra Firma Lite clock, including all parts and labor, less
shipping and handling charges, is $1,995. With the ultimate externally
mounted Uber Clock, the price is $2995.True
dual differential balanced output is also included.
Shipping charges are quoted
individually, as rates vary with packaging,
distance and carrier. Our limited warranty on the
modification ONLY, is 5 years, parts and labor. Please be
aware that Sony Corporation may take the position that
this modification has completely voided their warranty,
but in most cases, it is possible for us to remove the
mod, temporarily, while the machine goes to Sony for free
warranty service. We may or may not be able to perform repairs
to a malfunctioning player.
