Outboard DACs

A dedicated stack that forms one of the most expensive digital playback systems on the market, Esoteric’s Grandioso P1/D1 is aimed squarely at fans of the SACD format

Let’s not beat about the bush: alongside the top-of-the-range, multi-chassis dCS Vivaldi pile [HFN Feb ’13] – I can think of no others in this category – the Esoteric P1/D1 combination SACD transport/mono DACs package will lighten your Amex by a worrying £49,500. That breaks down to £33,000 for the two-chassis player/power supply and £16,500 for the mono DACs. Oh, and if you really want to go the whole hog then the Grandioso G1 Master Clock, not supplied here, adds another £23,000.

This Polish tech brand has already made waves with its OOR headphone amp and DAC-equipped ERCO. Now comes its most sophisticated digital offering yet – the Wandla

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.

You may be forgiven for having not yet heard of Firestone Audio though its quirkily designed little boxes appear to be gaining something of a cult following. Made in Taiwan, there’s a plethora of components in Firestone’s range, encompassing phono preamplifiers, various solid-state and valve headphone amplifers including a battery powered model, digital-to-analogue converters and even a dinky little 8W stereo power amp dubbed Big Joe. One of its headphone amps is called Cute Beyond. Did I mention that these miniature boxes looked cute? Funny, that; Firestone calls them the Cute Series.

Korea's Citech group continues apace with yet another 'full colour widescreen' offering from its HiFi Rose brand – this time with an updated network-attached media hub

ARose by any other name? As has happened in the past, Korean manufacturer HiFi Rose has launched a new version of an existing model – in this case its RS250 network player – with worthy specification changes and a suffix to set the two apart. But there's a mild inconsistency here, for when the company upgraded the RS150 [HFN Jun '21] to the current version, due to a DAC chip change forced upon the company by the 2020 fire at AKM's semiconductor plant in Japan, it became the RS150(B), selling for £3899, but the revised RS250 is now the £2349 RS250A, available in either silver or black finishes.

Launched a little after Halloween, iFi Audio's devilish top-of-the-range portable aims to put a bat up the nightdress of the competition. Are you ready to sell your soul?

With its wide range of portable, battery-powered DACs and headphone amplifiers, few companies have done as much as iFi Audio to improve listening on the hoof. Yet the new iDSD Diablo 2, its latest range-topping model and a replacement for the iDSD Diablo of 2021, pushes the envelope of the mobile DAC/amp genre, both by being far from budget at £1299, and large enough for its manufacturer to deem it more 'transportable' than genuinely 'pocket-size'.

Launched with a typically dazzling array of acronyms, the NEO iDSD is nonetheless a more focused DAC/pre/headphone amp, equipped with the latest 'hi-res' Bluetooth

Seemingly there's no stopping Southport-based iFi Audio: it just keeps on trotting out new digital products, all aiming to fill a gap in the market – or create a new gap to fill. Indeed, while writing this review I was unsurprised to see another new launch pop up, in the form of the bright red iDSD Diablo.

The most ambitious iFi digital product to date is a hugely flexible DAC/headphone amp with an eye on both studio and consumer markets. But is it just a bit too complex?

The idea of the DAC/headphone amplifier is firmly established, whether for ‘on the go’ use, desktop audio or as a main system component. Less than £100 will get you started, with the likes of the AudioQuest DragonFly Black [HFN Oct ’16], Cambridge Audio DacMagic XS V2 or Cyrus SoundKey, while the ambitious might consider models such as the long-running Chord Electronics Hugo [v2, HFN Aug ’18] and costing the thick part of £2000. However, even by the standards of this highly diversified market sector, the range-topping model from iFi Audio, the Pro iDSD, looks pretty punchy with its £2500 price-tag.
