SONY SUPER AUDIO CD PLAYER
ULTIMATE UPGRADE SERVICE
(or "We have heard the future of high fidelity
music reproduction, and it is here today!")

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 (SACD) format.

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 processing artifacts.

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, including all parts and labor, less shipping and handling charges, is $1,995. 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.
