Description
>>IDEAL FOR AUDIOPHILE COLLECTORS SEEKING STATE OF THE ART DAC PRODUCT<< The item is a fully functional, and in exceptional condition suitable for collectors and audiophiles, a Pioneer DV-AX10 SACD/CD/DVD-A player 24-bit/192kHz. It comes with the original user manual, remote, and power cable. The player is very beautiful and impressive to look at with solid copper back and underneath. It is extremely well built and very heavy. The outside is a shiny Champagne like gold finish. Description of Unit Single-box SACD/DVD-Audio/DVD-Video/CD/CD-R with onboard Dolby Digital, DTS, and two-channel SACD decoders. Chipsets: Analog Devices Multi-bit 24-bit/192kHz D/A converters (front L/R), Analog Devices 24/96 D/A converters (center, surround, subwoofer) with Hi-Bit Legato Link Conversion. Digital outputs: 24/96 S/PDIF (not for SACD). Frequency response: 4Hz-88kHz (DVD-Audio at 192kHz sample rate). S/N ratio: <115dB. Dynamic range: <108dB. Power consumption: 58W. Dimensions: 17 1/6 (440mm) W by 6 (150mm) H by 15 9/16 (394mm) D. Weight: 53 lbs (24kg). Stereophile Magazine Extract The DV-AX10 weighs 53 lbs and is built like a tank. Beneath the central display, an acoustic damping tray, as Pioneer calls it, drops smartly down and out of the way, allowing the drawer to open. The outer door also functions as a double air-lock for better isolation. Around back are plainly marked single-ended (RCA) and balanced (XLR) connectors, selectable by switch. Above those are three additional jacks, for 5.1-channel systems, and next to all that are a pair of Pioneer System Control In/Out jacks, two Video Out jacks, a pair of S-video outs, and component-video outputs with a few switch-selectable adjustments. On the far right are the digital outs on TosLink, two S/PDIFs that can pass 24-bit/96kHz signals, and another jack, marked PDIF, for a Pioneer Digital Control Amplifier such as the C-AX10. Pioneer uses a pair of Analog Devices multi-bit 24-bit/192kHz D/A Converters for two-channel stereo and the front L/R channels, and three more 24/96 DACs for 5.1-channel surround. Dolby Digital and DTS decoding for multichannel DVD-Video playback are also provided. For better or worse, they've also thrown in their Hi-Bit Legato Link Conversion, which can't be defeated. Of interest is what Pioneer's press pack calls the high-sampling digital filter, which removes the cumbersome harmonic distortion and efficiently reproduces only the 192kHz high-sampling frequency. Pioneer has also implemented what they call a Pure Audio Clock Reference, which automatically converts the crystal clock oscillator to either the 44.1kHz lineage frequency oscillator (44.1kHz, 88.2kHz, and 176.4kHz), or the 48kHz lineage one (48kHz, 96kHz, and 192kHz). The circuit turns off the unused oscillator to avoid unwanted resonance that could lead to sound degradation. Fortunately, once the DV-AX10's defaults have been set via screen menu input, the CD Digital Direct button can be pressed; this bypasses the DSP and routes the audio signal directly to the output. An improved signal/noise ratio is claimed for this little circuit. To further improve the sound, according to Pioneer, one disables the video circuits by pressing the Video Off button, to eliminate even the tiniest noise generated by the video circuit. Another button dims the small but informative built-in display, then cycles it off. This display is a model of how a small but informative display for multifunction environments should work, he said, emphatically shaking his jowls. What seemed unique to me was that, among the many chunks of information displayed, standard are the bit rate and speed of whatever's playing, along with an LPCM (Linear PCM) or SACD indicator, whichever's the case.
