Arcam has a fiercely earned reputation for high-end stereo equipment aimed at those who would happily describe themselves as audiophiles. At first glance, the DT-91 is a well-built separates unit with both analogue and digital audio outputs to interconnect your existing stereo system.
You'll need an existing amplifier and speaker set to plug the DT-91 into because, unlike radios like the, this Arcam does not have a built-in headphone jack. Listening without a headphone pre-amp or hi-fi amplifier is not possible.
DAB stations in the UK use bit rates that continue to disappoint us (as low as 80Kbps), but for audiophiles there is always the option of listening to FM broadcasts on the DR-91 where they're available. One reason to listen to DAB, despite its sub-par bit rate, is the sheer choice of stations. Can the DT-91 justify the investment when it comes to decoding and playing DAB broadcasts?
The front panel on the DT-91 is dominated by a large, central tuning dial -- this rapidly scrolls through stations like a traditional analogue tuner. The majority of controls are clearly displayed to the left of this.
The unit is noticeably lightweight -- an inevitable consequence of the minimal size of the electronic circuits needed to operate a DAB/FM combo these days. Arcam has done a reasonable job of bulking up the unit, but as with all DAB manufacturers, you get the impression that it struggled to fill the large 19-inch chassis of a standard hi-fi component. As a result, the DT-91 feels hollow and the buttons make an empty clicking noise. We're used to something a bit more hardy from Arcam in this respect.
A large, bright LCD display is to the right of the central tuning dial. You can summon menus, change band and recall memory presets using the menu and select buttons. These buttons are comfortably sized and quick to locate.
The DT-91's standard 19-inch case stacked neatly on our existing hi-fi separates. The feet on the unit raise it about 10mm off the ground, providing adequate ventilation for an amplifier placed below.
The rear panel on the Arcam offers a selection of outputs in the form of digital optical, digital coaxial and two sets of left/right gold-plated phono connectors. There's also a Remote In and an RS232 port for external control.
The DT-91 tunes rapidly -- a similar speed to other separates we've tested. DAB stations are automatically listed, and you can move through the station listings using the tuning wheel. Initial setup is as easy for first-timers as it will be for anyone familiar with using a DAB.
