Due to circumstances relating to this product, it is only available in the UK to special order, which means it is not stocked as standard in our warehouse. A special order item will be placed on order with the relevant manufacturer during our next scheduled Purchase Order. As we forecast orders up to two months ahead of time with some suppliers, this does not mean the item will automatically be included on the next shipment we receive. It also does not mean that the item will immediately be placed on order with the supplier, as we group special orders together for logistical purposes. Therefore, we estimate lead times on most special order items of 8 – 12 weeks.

The Performance Anniversary is a special edition version of the Performance integrated amplifier. Benefiting from the same superior design and build characteristics of the standard model, the Anniversary edition uses upgraded valves to enhance the sound performance more than ever before.
Built to celebrate the 25th anniversary of Unison Research, the Performance Anniversary - like the Sinfonia Anniversary below it - uses class-leading Gold Lion valves designed by Genalex. Since its initial introduction in 1957 by the Marconi-Osram Valve Company (Genalex), the Gold Lion KT88 has been widely considered to be the "King of Power Tubes", which is why their addition to the Performance can improve the sound so dramatically. All Gold Lion valves are meticulously engineered to provide a lower noise floor, a broader frequency range and a larger more detailed sound-stage than many other valves on the market.
Visually, the Performance Anniversary also stands out as unique thanks to it bronze top-plate, as opposed to the Sinfonia's usual stainless steel plate.
