Exemplar Audio Oppo BDP-105 Tube Modification

The Oppo BDP-105 is well known to audio and home theater enthusiasts for its versatility and ability to play movies and music in almost any format.  To top it all off, it sells at a reasonable price point.

To bring the impressive BDP-105 up another notch, John Tucker of Exemplar Audio has designed a modification that includes both a new tube output stage and a very significant upgrade that includes a separate outboard power supply just for the output stage.  The modifications affect only the stereo audio output of the Oppo. The result is an audio improvement that puts the BDP-105 into a class with the best stereo components, regardless of price.  Be prepared for a major step up in sound quality with greater clarity, range and an improved sound stage.  It’s as if a veil has been lifted and the detail and nuances of the music are now revealed.  Our customers have been delighted with this upgrade and we think you will be too.
