Ultrafide Audio is taking its pro sound, homebound revolution one step further with the launch of our SP500 stereo power amplifier, which is being officially unveiled at 2025’s Edinburgh HI-AV Show, 8-9 November.
As teased earlier this year, the SP500 is a sleeker, more compact and more affordable addition to Ultrafide’s range – but with the same power output, warm sonic purity and music-first ‘power with emotion’ engineering excellence Ultrafide is becoming known for.
Retailing at £3,990 (incl VAT) – SP stands for ‘squaredPOWER’ and a nod to MC²’s approach, the SP500 features Ultrafide’s Ultra Sigma output topology, the company’s premium in-house design that was first introduced in the U500DC – it delivers superior audio performance to rival anything on the market.
Its elegant, minimalist design and compact straight edge casework means that the SP500 seamlessly integrates with other hi-fi components and mixed systems, and is also perfectly suited to studio, reference, and residential applications with its ability to be rack mounted.
DC coupling input to output ensures clean and accurate signal transmission, a PURE timbre sonic signature: providing an incredibly transparent, but musically engaging experience. It also offers flexible configuration with RCA and XLR inputs, XLR passive link outputs, and both binding post and speakON outputs. A true nod to classic MC² Audio thinking!
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!”
Alongside the SP500, Ultrafide will be setting up with Kudos 505 speakers at the Edinburgh HI-AV Show, forming a compact but formidable and high quality set up for visitors to the room to enjoy.
