ifi hip-dac
ifi's hipflask-shaped digital-to-analogue converter delivers high-quality sound on the move
ifi looks determined to dominate the affordable digital-to-analogue converter market. For the hip-dac, ifi has taken the guts of the excellent, desktop-based Zen DAC and crammed them into a smaller, battery-powered form. The name comes from its resemblance to a hip flask.
The hip-dac is a nicely made unit with an extruded petrol blue aluminium case that’s about the size of a pack of cards. The finish is neat and the metal volume control (that also doubles as the power switch) has a pleasantly damped feel.
Input is limited to a male USB Type A, which means that the DAC can connect directly to the Apple’s Lightning-to-usb (camera adaptor cable) needed to use an iphone as source. You’ll have to buy that Apple cable separately, but ifi provides short cables that terminate with either USB Type A or USB Type C in the box.
3.5mm and balanced outputs
There are two outputs – a conventional 3.5mm headphone jack or a balanced Pentaconn 4.4mm alternative. The balanced output is claimed to take full advantage of the DAC’S similarly configured internal circuitry, and gives the hip-dac a USP compared with most rivals. None of our favourite headphones at this level come with a balanced connection, so we’ll park its inclusion under interesting, rather than essential.
A 2200mah battery provides internal power, and there’s a small LED under the USB Type C charging port that indicates remaining reserves. A full charge is claimed to take around three hours and gives eight to 12 hours of use, depending on the headphones and volume level. Of course, such figures are merely guidelines and much depends on the headphones and volume levels used – a point reinforced during our testing.
We try the hip-dac with a variety of headphones, from Shure’s SE535 in-ears to Sennheiser’s Momentum 2.0 over ears and Beyerdynamic’s demanding T1s. The hip-dac managed three hours driving the last of these before needing a charge, but was much better with the others.
On the front, there’s a button that changes the gain of the internal amp. This makes headphone matching easier, with less sensitive models needing the volume boost. We’re not usually fans of bass emphasis controls, but the one on this unit is subtle enough to be useful. It adds an appropriate degree of low frequency heft to the Shure in-ears without sounding over-blown.
ifi’s products rarely disappoint on the compatibility front, and this one is no different. The hip-dac will work with up to 32-bit/384khz PCM and DSD256 files. MQA is also on the menu.
There’s a pair of LEDS, one on either side of the volume dial, that indicate the sampling rate and type of file. They’re not particularly informative, as they don’t differentiate between the most common PCM file types. For example, 44.1khz and 96khz files are each represented by the same green light. Equally, everything from 176.4 to 384khz files is indicated by yellow. Even the DSD files are lumped together without much thought.
The hip-dac is up against some tough competition – the Cyrus soundkey and Zorloo’s Ztella set high standards at less than £100, while Audioquest’s Dragonfly Red (£135) delivers exceptional sound quality. For portable use, Audiolab’s bluetooth M-DAC nano (£139) remains hard to beat. Yet, even against such capable opposition, there is a place in the market for the hip-dac.
It’s not as small as its rivals and can’t match the wireless connectivity of the Audiolab, but with battery power built-in, the ifi won’t drain your phone or laptop.
The hip-dac is a hugely capable performer with the typical easy-going ifi sound. It’s a balanced presentation that’s refined and free of harsh edges. You can listen to the hip-dac for hours and not feel fatigued. Yet unlike some of the company’s older products, this undemanding nature is still partnered with expressive dynamics and pleasing rhythmic precision.
Punch and drive
Listen to Neneh Cherry’s Blank Project and the ifi delivers the music with a good amount of punch and drive. Cherry’s voice comes through with nuance while there’s enough in the way of organisation to keep the instrumental backing easy to follow. Basslines punch through the mix with purpose, agility and power. The lows are rich in absolute terms, but no part of the frequency range grabs the limelight unduly.
We switch to Mahler’s Symphony No.4 and the ifi responds with a spacious and composed rendition. It’s a little smooth tonally, but that just serves to make it less critical of source quality – an important consideration with a product such as this. There’s a good sense of scale and focus, with the hip-dac conveying the majesty of the piece well. The ability to organise detail into a cohesive and musical whole is obvious, and the ifi never sounds out of its depth.
If you’re looking for a high quality portable DAC, the ifi hip-dac is worth a place on the shortlist. A combination of battery power, fine build and easy-going sound quality makes it one of the front-runners at this level.
