Graham Slee DIY Upgrade Kit (Solo to Ultra-Linear Diamond Edition)

Buy the latest Graham Slee Solo Ultra-Linear Diamond Edition board for your older Solo Headphone Amp, and fit it yourself following the instructions on this page.

This official Graham Slee upgrade board works with all Solo units made from early 2004 - check appearance in the images above.

The board offered here is the same as is fitted to the factory-made Solo Ultra-Linear Diamond Edition headphone amplifiers. It has been fully tested and meets GS specification.

The price is substantially lower than if the sum of parts of a new Ultra-Linear is considered. This is because Graham Slee are not doing the final production testing of a fully-built unit, or the packaging, and there is no distribution profit margin - so you make a tidy saving.

Graham Slee are unable to include the Ultra-Linear panels because if the unit was to be eventually sold it would not be a factory-made Ultra-Linear, and this would not be fair on the new owner. Therefore, the original panels have to be used.
