The Audio Upgrade replaces key components in the audio signal path to provide improved audio quality. The end result is that the audio will sound clearer with improved detail. Overall intelligibility is improved.
Please note: This performance kit is more difficult to install than others due to the fact that removal of the main pc board is required. Proper tools are essential. We recommend a good fine tipped soldering iron, a small/long needle nose pliers and a small philips screwdriver such as a Wiha 261 (PH 0x50). None of the components to be replaced are surface mount. However, the components removed will be next to many small surface mount components. Complete installation instructions are included.
