Ultrafide Announces Accessible Power Amplifier

Ultrafide has announced the SP500 amplifier today, billed as a more accessible model, retailing at £3,990 (incl. VAT).  This power amplifier has the same power output as the U500DC, which introduced its premium in-house design, the Ultra Sigma output topology.

The new casework is minimalist with straight edges, enabling it to integrate with other Hi-Fi and bespoke stacks.  The SP500 amplifier offers a flexible configuration with RCA and XLR inputs.

Ultrafide stands for ultra-fidelity audio, and following parent company MC2’s pioneering work in live and studio sound for three decades, it is now concentrating on the domestic market.

Mark Bailey, product specialist at Ultrafide Audio and MC2, said:

The SP500 is everything that’s loved about our U500DC Ultra Sigma amplifier, but with a more minimal approach to its casing that we really like and have been asked for on numerous occasions. We’ve added the additional ability to rack mount, and made some clear I/O connection differences to make it even more flexible and applicable to CI, studio, cinema markets, as well as traditional Hi-Fi. The internals of the SP500 are almost identical to that of the U500DC, with just a subtle change to input/output circuitry, so the performance is equally breathtaking.

We can’t wait to formally unveil the SP500 at this year’s Edinburgh HI-AV Show and will have more exciting news within the region coming soon…

Remember, Pro sound is homebound!

Ultrafide is launching the SP500 and exhibiting at the Edinburgh HI-AV Show on Saturday, 8th November 2025 and Sunday, 9th November 2025.
