That this is a high resolution player is underlined by its balanced XLR outputs on the rear panel. There are two USB mass storage sockets, one HDMI input and two HDMI ouputs, one streaming native DSD. Note also eight multi-channel audio outputs.


Now to a few small funnies and limitations. Under test I found the S/PDIF inputs went silent when fed 176.4kHz or 192kHz sample rate digital, odd since this is not a limitation of the Sabre32, and electrical S/PDIF, at least, always works to 192kHz these days. Unfortunately, on the BDP-105D it does not and the User Manual confirms this in a note on p21. I got silence when playing back ‘192s’, like Otis Redding’s ‘Otis Blue’ (24/192) from my Astell&Kern AK120 portable player via its optical digital output. This was an unexpected limitation.
    The question then arose: would it play 24/192  WAV and FLAC files from a memory key? It did, playing test files perfectly. It also plays DSD files with .dff and. dsf file extensions. This is a peculiar inconsistency: via S/PDIF it won’t play top resolution files, but from a memory key it will. 
    So on to USB - and here it became even stranger. Oppo quote 192kHz sample rate, but our UK sample player signalled to my MacBook Pro (OS: Mavericks) it accepted 384kHz sample rate - and it did! The Sabre32 will work up to this rate, so its powers have been fully exploited via USB. There are no file limitations, as long as the music player in use can play them, but I could not get sound when playing DSD files (.dff and .dsf) with Simple Audio player and Audirvana, even though the Oppo saw a 358.2kHz sample rate PCM input from my MacBook Pro, indicating it was getting a high resolution data stream. It may just be it was detecting a high rate DSD stream, flagging it erroneously as PCM. Whatever - I got silence over USB, although the Mac was playing, connected headphones showed.
    Other small limitations to be aware of are that the video side inevitably has regional management and ours was a Blue-ray Region B / DVD Region 2 (Europe) player, not a U.S. A/1 player. Also, although DVD-A discs are played, HD DVDs are not. SACD discs are played, in full multichannel form and output over HDMI2 can be set to DSD for a receiver that can process DSD, or PCM for a receiver that cannot. Note that internally the Sabre32 processes DSD from SACD discs and outputs it via the rear panel analogue audio outputs, so you get the quality of the Sabre32 here - and measurement showed excellent figures from an SACD test disc.

In use I found the remote control a mixed bag. It has a good Direct button that switches off internal video processes and sends a black signal over HDMI so there is no high frequency (data rate) info on the R, G and B data lines. It has a strong back light for the buttons too and audio functions are conveniently in a line at top.
    The remote was just-about legible in low lighting. Some of the user-interface behaviours were odd: why step through a menu with the Audio selection button, for example, when up/down buttons on a joy stick are purposed for this and used elsewhere?
    I started out playing a Blu-ray I know well, John Meyer’s ‘Where the Light Is’ and stopped immediately: the picture was too contrasty. Switching video to ‘straight through’ cured this and I got on with listening.
