• Built in DC Phase Linearizer. Where Sony's 24-bit LSI required a second

chip to contain the DC Phase Linearizer, this circuitry is built right into Sony's

32-bit design. The process is performed by Infinite Impulse Response (IIR)

calculation, which processes more data in less time.

In this way, Sony has taken the critically-acclaimed S-Master Pro amplifier

to a higher level of precision and performance. Those fortunate enough to own

of the STR-DA7100ES will experience superb clarity of expression, relaxed

listening hour after hour, and the effortless dynamics to handle everything from a

the Dies Irae of Verdi's Requiem to the meteor impacts of the latest action movie.

The Low Pass Filter is a crucial stage in any digital amplifier. The filter

must have a turnover frequency high enough for high-resolution audio, yet have

a cutoff characteristic steep enough to suppress high-frequency noise elements.

In this way, the filter has a major influence on sound quality. That's why the

engineers of Sony ES selected the filter parts carefully and methodically. Instead

of choosing less expensive cylinder-type coils, the ES engineers chose exotic

toroidal coils, optimized for sound. Customers will never see these toroidal coils,

but they will hear the benefits in clean, open, non-fatiguing music reproduction.

Shown here wrapped in black, the toroidal coils of Sony's Low Pass

Filters are more expensive. But their contribution to sound is more than

worth the price.

In traditional amplifiers, the output transistors or ICs directly shape the

analog waveform. For this reason, traditional amplifiers are extremely sensitive

to the selection, configuration, bias current and heat sinking of their output

devices. By their design, digital amplifiers are inherently less sensitive to these

factors. That's why some previous digital amplifiers have used relatively

inexpensive integrated circuit op-amps at the output. But Sony ES engineers

were after the best possible sound. So they selected deluxe Metal Oxide

ES Receivers v1.0
