Outboard DACs

Does the world really need another DAC? Considering the ample offerings from traditional and emerging Asian hi-fi brands, you might be tempted to say, 'not really'. However, Poland's Ferrum Audio combines experience with a flair for innovation – its parent company HEM has been an OEM contractor for other manufacturers, possibly inciting its engineers to go one better for their own brand.

All good things come to an end, although in the world of digital hi-fi sometimes that end comes around pretty quickly. Obsolescence isn't as 'built-in' here as it is in the smartphone market, for example, but technological evolutions, be they around chipsets, connection standards or format types, mean 'MK2' iterations of DACs and streaming hardware are a common sight. PS Audio's DirectStream DAC MK2, however, is rather more than a mere second-generation product.

Maybe it's a sign of the times, or the state of the specialist high-end audio market, but this latest version of dCS's Bartók streaming DAC, often referred to as the company's 'entry-level' model, is now almost twice the price of the original [HFN May '19]. Then, the Bartók was £9999, or £11,999 when fitted with the optional headphone amplifier; now the Bartók APEX, taking on board the company's latest package of enhancements, first seen in the Vivaldi APEX [HFN Jun '22], is £19,000, rising to £21,500 if you choose to take the headphone option.

To say iFi Audio is an industrious producer of compact hi-fi solutions would be an understatement. More recently the brand has been on a steep upward path of technical evolution, employing designers as accomplished as the marketing department is imaginative. The result? IFi Audio is successful because it has identified new hi-fi hotspots that appeal to both younger and older music lovers alike.

Although Auralic (promoted as AURALiC) only launched the Altair G1 in 2020, the Chinese brand already has its G1.1 update available. It appears together with the Aries G1.1 as the new and more affordable options within their respective tiers, with the Altair and Aries G2.1 [HFN Oct '21 & Feb '21] being the more expensive models. However, as all Auralic products share a very similar chassis design and carry names that aren't very descriptive, it's sometimes difficult to discern which box does what.

Many manufacturers building tube-based products seem to prefer retro-nostalgic designs but Slovakia's Canor is one of the few that favours a more modern, progressive aesthetic. It not only produces tube amplifiers but also integrates line-level tube stages into source products, such as the CD 2.10 CD player [HFN Apr '21]. The partnering DAC 2.10 also marries an output stage containing four Electro-Harmonix 6922EH triode tubes with a digital mainboard, the latter equipped with a pair of ESS9038Q2M DACs. Otherwise this is a dyed-in-the wool 'legacy' DAC with no network or wireless functions and a fixed rather than variable output. So that large rotary is not a volume control…

At first glance, one might wonder why Matrix Audio felt any need to update its Element X network DAC [HFN Jan '21], the latter receiving our 'Outstanding Product' tag at £2795. However, look at this new X2 model and – while it's still conceptually the same, with a broad retention of technology from the ESS ES9038PRO DAC to the Crystek clock – it's clear much has also changed.
