This listing is for a tested and working Sony SCD-XA777ES multichannel SACD player. It's in very good condition for its age. Well preserved all these years and a great addition to your audio collection. I have tested all the components I could and everything seems to work just fine, with exception to SACD's because I don't have any SACD's to test with. Never even knew they existed! All RCA ports work fine. Unable to test the digital port as I don't have that cable. Looks like it was never used.I took a short video playing a regular music CD to show it works nicely.The remote still works, but old batteries were left in it and corroded the terminals a bit. This could easily be cleaned up though and the damage is minimal, as seen in the pictures.Player comes with remote, owners manual and power cord only.This player will be professionally packaged and will include insurance in the shipping cost. Local pickup is also available.Below are all the specs I could find for this player.Details:plays multichannel SACDs, stereo SACDs, CDs, audio CD-Rs, and audio CD-RWs6 Super Audio D/A convertersTri-Powered DAC systemframe-and-beam chassis3 audio circuit boardsdual-laser (1 for SACD, 1 for CD) optical pickupmultichannel bass management and level control5.1-channel and stereo analog outputs (for 5.1-channel SACDs, stereo SACDs, and standard CDs)optical and coaxial digital outputs for CDtwin large R-core power transformersremote controlSACD playback specifications:frequency response 2-50,000 Hz0.0012% THD108+ dB dynamic range16-7/8"W x 5"H x 17-1/16"DNote: Multichannel SACD playback requires 5.1-channel input on receiver or preamp.Features & specsGeneralDisc CapacityN/ACD Transport OnlyNoDisc ExchangeN/ATrack Programming32Random PlayYesDirect Track AccessYesDirect Disc AccessN/ANetworking FeaturesNetwork Music Streaming---Ethernet Port---Wi-Fi---RemoteIncludedCompatibilityCD-R PlaybackYesCD-RW PlaybackYesStereo SACD PlaybackYesSpecificationsCD Frequency Response2-20k HzSignal to Noise RatioNot GivenSACD Frequency Response2-50k HzSACD Dynamic Range108 dBSACD THD0.0012 %InputsDigital Optical InputDigital Coaxial InputUSB Type-A InputUSB Type-B InputOutputsAnalog RCA OutputNoAnalog XLR OutputNoDigital Optical OutputYesDigital Coaxial OutputYesHeadphone OutputStandardFeaturesDisc Compatibility: This unit can play the following discs:Conventional audio CDsSingle layer 2 channel and Multi-channel Super Audio CDs: These can hold up to 74 minutes of music and are playable ONLY on an SACD compatible unit such as thisDual layer 2 channel and Multi-channel Super Audio CDs: These discs hold dual layers of high density information for longer playing times (one side only, so the disc does not have to be turned).  These discs are playable ONLY on an SACD compatible unit such as this.2 channel and Multi-channel Super Audio CD + CD (Hybrid disc): These discs have a high density SACD layer and a CD layer, allowing them to be played either on an SACD compatible unit OR on a regular CD player which can read the CD layerCD-RCD-RWDirect Stream Digital (DSD) Encoding: Super Audio CD uses DSD encoding (compared to PCM used for CD/MiniDisc/DVD/Audio DVD, etc.). DSD uses a sampling frequency 64 times higher than conventional CD (2,822,400 samples per second) and 1-bit quantization which does not require decimation or interpolation filters. This achieves both a wide frequency range and a wide dynamic range across the audible frequency range, thereby providing musical reproduction extremely faithful to the original.2-Channel and Multi-Channel SACD Playback: In addition to standard 2-channel CD playback, this unit will play 2-channel and multi-channel Super Audio CDs. During SACD playback, the digital outputs do not operate; the analog outputs must be connected to listen to SACDs. There is one set of stereo RCA outputs for standard 2-channel playback, and there is a set of 5.1-channel RCA for multi-channel playback. For multi-channel playback, the 5.1 channel outputs must be connected to a multi-channel input on a receiver or preamp. Multi-channel SACDs may have 3, 4, 5 or 6 channels of audio. Note: During multi-channel playback, there is no output from the 2-channel RCA outputs, and during 2-channel playback, there is no output from the 5.1-channel RCA outputs.Super Audio DAC System and Direct Digital Synch D/A Clock Converter: This unit is built with a new Super Audio DAC system (SA DAC) and a Direct Digital Synch D/A clock converter for enhanced sonic performance.Tri-Powered DACs: Because this unit offers multi-channel output, it has six digital-to-analog converters (DACs). When a two-channel disc is played, each channel is passed through three DACs, thus improving the signal quality and signal-to-noise ratio.Multi-Channel Management Function (bass management): The Multi-channel Management Function allows you to set up the unit according to the layout and size of your speakers; this feature applies to SACD playback only. For the multi-channel playback mode, speakers designated as "Large" will be sent full-range audio, while speakers designated as "Small" will receive signals that have been filtered to remove low bass frequencies. For proper channel balance during multi-channel playback, the center, surround and subwoofer channel output levels may be adjusted at the unit or with the remote.Digital Outputs: There are both coaxial and optical digital outputs on this unit. The digital outputs are active only when playing a standard CD. Because of the quality of the DACs in this player, one might choose not to use the digital outputs; in this case they can be turned off.Digital Filter: When playing a standard CD, the digital filter can be set to "standard" or "option." Standard provides a wide, spatial feeling, and option offers smooth and powerful sound with a clear image position.Frame and Beam Construction: Using asymmetrical frames and beams, the ultra-rigid chassis reduces resonance to maintain sound quality. The analog, digital, and power supply sections are completely separated on 3 audio circuit boards to reduce any possible noise from affecting the audio signal. SACD/CD Switching: The unit automatically determines the format of an SACD or CD disc. However, an SACD/CD button on both the remote and the unit allows you to select the format in the case of a hybrid SACD/CD disc. Also, there is a MULTI/2CH button on the unit and remote that allows you to choose between the 2 channel and multi-channel sections of a SACD that contains both types of tracks.SACD and CD Text Compatible: This unit can display the disc name, artist name, and current track name (14 characters will appear at once, after which the display will scroll) for compatible CDs with CD Text and SACDs (most of which will have text).20 Track Music Calendar: A calendar-like display lights up with the number of tracks on the currently selected disc. After a track has been played, the number for that track disappears from the calendar display.  Display: The display can be set to show current track/index/elapsed time, current track/remaining time, remaining time for entire disc, or Text information. The display can also be turned off.Program Play: Up to 32 tracks can be programmed and played in any order.Shuffle Play: This unit can play the tracks on the disc in random order.Repeat Play: This unit can repeat the current track or all the tracks, repeat Shuffle play, and repeat Program play.Remote ControlRM-SX700 Remote: The remote is pre-programmed to operate this unit and a number of functions on other Sony CD players. The remote's codes correspond to Sony CD Player codes, so many of its functions can be operated with a normal Sony receiver or preamp remote control.Inputs and OutputsFront Panel:Phones: standard gold-plated headphone outputRear Panel:2CH Analog Out: left and right gold-plated RCA jacks. Note: Since audio from SACD discs is output only from the analog outputs, this set of outputs must be connected to the receiver or preamp to listen to 2-channel SACD discs.5.1CH Analog Out: left front, right front, center, left surround, right surround and subwoofer gold-plated RCA jacks for connection to a receiver or preamp with a set of 5.1-channel inputs. Note: Since audio from multi-channel SACD discs is output only from the 5.1CH analog outputs, this set of outputs must be connected to the receiver or preamp to listen to multi-channel SACD discs.Optical Digital Output (CD only): one Toslink optical digital output with a plastic cover. Note: Only 16-bit PCM digital signals from a CD, or the CD layer of a Hybrid SACD disc, are output through the digital outputs.  SACD signals are only output through the analog outputs. This is done both for copy protection issues and the fact that SACD signals are not PCM, thus they cannot be recorded by current consumer digital recorders.Coax Digital Output (CD only): one gold-plated RCA digital output. Note: Only 16-bit PCM digital signals from a CD, or the CD layer of a Hybrid SACD disc, are output through the digital outputs.  SACD signals are only output through the analog outputs. This is done both for copy protection issues and the fact that SACD signals are not PCM signals, thus they cannot be recorded by current consumer digital recorders.SpecificationsWhen a Super Audio CD is played:Playing Frequency Range: 2Hz to 100kHzFrequency Response: 2Hz to 50kHz (-3dB)Dynamic Range: 108dB or moreTotal Harmonic Distortion Rate: 0.0012% or lessWhen a CD is played:Frequency Response: 2Hz to 20kHzDynamic Range: 100dB or moreTotal Harmonic Distortion Rate: 0.0018% or less
