Lewis CaliburnUltrafide Audio has launched the SP500 stereo power amplifier, which is being officially launched 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.
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. According to the manufacturer, 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 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 a 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.
Ultrafide stands for ultra-fidelity audio and following parent company MC2’s work in live and studio sound for three decades, it is now focused on the domestic market.
Lead product designer, audio engineer and pro audio legend Alex Cooper was given a blank canvas with which to operate for Ultrafide products and freedom to over-engineer.
Mark Bailey, product specialist at Ultrafide Audio and MC2, says, “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.
