I buy only from these approved sources. I can't vouch for ads below.

The Sony SCD-XA777ES was Sony's $3,000 flagship 36-pound (16 kg) single CD and SACD player of 2001-2004. Sony fielded this player mostly as a "halo" product and to promote the SACD format. It plays both CDs and SACDs.

As the "777" model number tells us, Sony planned for this to be their greatest player ever.

It has both RCA coaxial and TOSLINK optical digital outputs (for CD only), and has both stereo analog as well as a dedicated six-channel analog output for 5.1 multichannel SACDs.

Better than modern players with only HDMI multichannel outputs for ratty A/V receivers, this Sony beauty has six discrete analog outputs from six premium DACs to feed to six channels of premium amplification. (one of these six is the "0.1" mono subwoofer output.)

Since it has six ultra-high-quality DACs for the six channel outputs, in stereo mode, it sums three DACs together for each stereo channel, lowering DAC noise and random distortion and artifacts by 10 dB compared to the performance of just one of them — and each one is as good as Sony knew how to do.

This player measures and sounds wonderful.

Much better than the jitter problems present with connecting any external DAC, this player, as all one-box players, locks its DACs directly to the crystal-controlled internal master clock and controls the platter speed as part of a servo loop controlled by the state of fill of the FIFO (first-in, first-out) read buffers, so jitter is a non-issue. Jitter is only a significant issue for playback if attempting to send a digital signal over an external cable between boxes where the platter speed isn't controlled by the DAC clock, and the DAC has to reconstruct a clock signal from the data stream instead. As you can see at the 10 kHz FFT, it's cleaner than high-end external DACs today.

Performance         top

Intro   Specs   Performance   Measurements   Usage   Recommendations   More



Reproduction this fine can really only be appreciated with the highest-definition transducers, like the Stax Omega II headphones. Used with the Stax and a good recording, close your eyes and you can see the performers, see them move around, see them turn pages, change fingerings, sing along, and creek in their chairs.

With SACDs, the XA-777ES' sound is also smooth and detailed. Even my original 1979 Cleveland Winds digital recording as reissued on SACD sounds stunningly smooth and natural, with none of the digital glare detractors thought it had when originally released on LP and CD. That first digital recording scared the pants off most of us when we heard it the first time for its dynamics. Today, the dynamics and virtuoso performance is there, and so is the naturalness.


Headphone Output

The internal headphone amplifier is much better for good, high-impedance headphones than the weak output of an iPod.

It's almost loud enough with a 600Ω Beyer DT880 even for classical recordings, and more than enough for popular recordings.

The level control sounds like it has a linear taper, meaning that the level doesn't get much louder past 12 o'clock. The two channels track very well at any setting you'll ever actually use.



The XA777ES is a 35+ pound all-metal beast. The headphone knob is plastic (and lacks the LED of the Sony CDP-X303ES), but the other buttons, the AMS knob and everything else are all metal. I'll bet you it has a lead weight inside; electronics really don't need to weigh this much, so Japanese makers often load weights under the guise of "stabilizers" into the case to pad it up. In any case, it feels good!



Track selection is fast and simple with the AMS knob. Pop a disc in the tray, spin the AMS knob, and the player is smart enough to load the disc and start playing.

There is no forward and backward scan button; you only can do that from the remote. Don't fear if your SCD-XA777ES comes with no remote; any Sony CD player remote works fine for all these playback controls.

Likewise, the only way to set the REPEAT options is with a remote control.

The buttons are clear and simple, but I'd still like them even bigger and bolder.

Likewise, the PLAY and PAUSE LEDs are just small dots above each button. I'd love it if they backlit the symbol on each button.

While the drawer is wonderfully smooth, solid and quiet, the spindle motor is slightly audible if you're only a couple of feet away.


Measurements (CD)         top

Intro   Specs   Performance   Measurements   Usage   Recommendations   More

All these measurements are made in 2012 on a player that was built in 2002, on the CD section only, playing the CBS CD-1 engineering test disc stamped in 1983.

The traces from the Rohde & Schwarz UPL laboratory analyzer are color coded for the Left Channel and for the Right Channel. When they don't lie on top of each other, it's due to channel imbalance.


Output Level, CD at 0 dBFS

Output Voltage

1.9649V RMS left, 1.9403V RMS right, 200 kΩ load.

This is 0.21 dB shy of 2 V.


Output Source Impedance

110.2 Ω at 1 kHz. Same at 50 Hz and 20,000 Hz.


Headphone Jack

About 3.5V RMS. See Headphone Amplifier Measurements.



-105 dBV A-weighted, playing digital zeros.

Since 0 dBFS is +6 dBV, this is a 111 dB signal to noise ratio, the highest I've measured for 16-bit playback.


Frequency Response


Line output at 0 dBFS, 200kΩ load. (CBS CD-1 track 11, R&S UPL.)

That's pretty flat. Let's greatly increase the vertical scale and see what happens:



Line output at 0 dBFS, 200 kΩ load. (CBS CD-1 track 11, R&S UPL.)

+0, - 0.07 dB is pretty flat. The biggest thing to note is that the channels are imbalanced by 0.107 dB, that is, the right channel is 0.107 dB lower than the left.

The -0.07 dB at 20 kHz response is quite likely due to the interconnect cable's capacitance. The SCD-X777ES' source impedance is 110 Ω, so only 600 pF would cause the same loss at 20 kHz.

Let's see what happens driving a 600 Ω resistor:


Line output at 0 dBFS, 600 Ω load. (CBS CD-1 track 11, R&S UPL.)

Aha! A half dB drop at 10 Hz. Obviously there is a coupling capacitor in there, but no big deal, the SCD-XA77ES isn't supposed to be driving 600 Ω loads from its -10 dBu RCA outputs.

And now let's see what the "Digital Filter" option does:


"Digital Filter: Option" response, line output at 0 dBFS, 200 kΩ load. (CBS CD-1 track 11, R&S UPL.)

Setting the "Digital Filter" to "Option" drops the response 2 dB at 20 kHz. I doubt anyone will ever hear this.


THD: 0.0006% (-104 dB)


Harmonic spectrum, line output, undithered 1kHz at 0 dBFS. (CBS CD-1 track 1, R&S UPL.)



Sony SCD-XA777ES THD, line output, undithered sine wave at 0 dBFS, 22kHz bandwidth. (CBS CD-1 track 11, R&S UPL.)



Harmonic spectrum, line output, undithered 1kHz sine wave at -20 dBFS. (CBS CD-1 track 18 index 6, R&S UPL.)


Jitter Output Spectra

As we can see (OK, as any engineer can see), jitter is well below audible limits. Even if you use a poorly-designed external DAC with no jitter rejection for some reason it ought to work great.

Sony SCD-XA777ES digital output jitter, Coax output, 3-foot cable. (roll-over to compare to optical.)

This is close to the limits of the analyzer, except for the spikes at 44.1 and 88.2 kHz, which are still tiny at 0.001 of a Unit Interval.



Sony SCD-XA777ES digital output jitter, TOSLINK output, 12-foot optical cable.

This is at the limits of the analyzer, except again for the minor spikes.


Analog Output Spectra

Let's see a zoomed FFT of a 10 kHz sine wave. Let's see what sort of spurs surround the carrier, which show us internal jitter:

Sony SCD-X777ES

Zoomed spectrum of 10 kHz 0 dBFS sine wave. (CBS CD-1 track 9, R&S UPL.)

This is very good; I haven't seen any external DAC be able to beat this. The skirt doesn't start to spread until -120 dB!


Sony SCD-X777ES

IMD spectrum at 11 kHz and 12 kHz 1:1. (CBS CD-1 track 13, index 2, R&S UPL.)


Sony SCD-X777ES

1,002.27 Hz 0 dBFS square wave. (CBS CD-1 track 16, R&S UPL.)

This is very clean, note how the strongest even-order component is only -81dB, and only on the right channel (in yellow).

Let's select the optional digital filter and see what happens:

Sony SCD-X777ES

1,002.27 Hz 0 dBFS square wave. (CBS CD-1 track 16, R&S UPL.)

As expected, the 21 kHz component dropped a few dBs.


Headphone Amplifier

Source Impedance

55.6 Ω at 1 kHz. Same at 50 Hz and 20,000 Hz.


Maximum Output Levels at maximum gain, 0 dBFS

200kΩ load: 3.818V left, 3.755V right @ 0.0004% THD.

600 Ω load: 3.495V, 3.438V @ 0.0005% THD.

300 Ω load: 3.222V, 3.171V @ 0.001% THD.

37.5 Ω load: 0.715V, 0.718V @ 0.1% THD (gain about 2 o'clock before clipping).


Level Control Channel Tracking


Right channel level versus left channel, vs. Headphone level setting. (positive means image moves to right. R&S UPL.)


Frequency Response


Headphone output driving 600 Ω resistor. (CBS CD-1, track 11. R&S UPL.)



Headphone output driving Beyer DT 880 (600 Ω). (CBS CD-1, track 11. R&S UPL.)



Headphone output driving Ultrasone Edition 8 at 100 mV. (CBS CD-1, track 11. R&S UPL.)

Obviously, the 55 Ω source impedance is letting the Edition 8's impedance hump boost the bass a bit.




Headphone output THD driving a 600 Ω resistor. (CBS CD-1, track 11. R&S UPL.)



THD, Headphone output driving Beyer DT 880 (600 Ω) at 1V RMS. (CBS CD-1, track 11. R&S UPL.)

Usage         top

Intro   Specs   Performance   Measurements   Usage   Recommendations   More



The Sony SCD-XA777ES has a standard HP power connector to which you need to attach the power cord of your choice. The US model seen here comes with a standard generous Sony-gray 8-foot (2.5m) power cord.



The manual cautions that SACD output is loaded with strong ultrasonic noise, so don't crank the levels during silence or you could fry your tweeters silently.

Sony says don't try to play discs with stickers.


Analog Outputs

Oddly only the connectors for the stereo output, or the connectors for the multichannel outputs, work at any one time.

Sony does this to emphasize the fact that they use all six DACs in parallel to create the stereo output, however this also means that one cannot get stereo output from the front left and front right connectors; it only comes from the dedicated stereo connectors.

This is great if you want the stereo output to connect to one place and the multichannel output to connect someplace else (as on a Sony receiver), but also means that you can't use the same outputs for both stereo and multichannel if that's how you setup your system.

Since the internal headphone amplifier is fed from the stereo output pair, the headphones won't work during multichannel output.

The only advantage for this is if you're wasting this great player with an A/V receiver, in which case by connecting the different outputs separately lets the receiver know what you're doing as you select each one: have stereo play as pure stereo, and maybe have your receiver screw with the 5.1 to model it to your speaker field.

Honestly, though, you could plumb the stereo outputs to your dedicated stereo rig, and send the multichannel outputs to your multichannel setup, keeping the two separate. There is no remote control of output level as there is on the Sony CDP-X303ES.


Digital Outputs

It's silly to use an analog masterpiece like this with an external DAC, but if you must, be sure to activate the digital outputs with the MENU button and the AMS knob.

If you don't the TOSLINK LED remains lit dimly, just enough to confuse folks into into thinking that the digital outputs are active.

When you do activate the digital outputs, the TOSLINK LED is very bright.

For about $950 used, the Sony SCD-XA777ES is a spectacular chunk of audio playback hardware and arguably the best CD and SACD player ever made. Enjoy the analog outputs for a jitter-free listening experience, especially if you're a 5.1 fan.
