Airspy HF+ will only give 660 kHz bandwidth - definitely not enough for DAB. So it would have to be the Airspy R2. Unfortunately they will not be making them any more as the R820T2 chips of the right quality are no longer available. So do not think for too long.
You can record 10 MHz bandwidth - which gives a usable 9 MHz without images. These show up at between +4.5 to 5 MHz from the centre frequency.
The Airspy mini is much cheaper but has a similar performance. As supplied it will do 6 MHz bandwidth, but a simple change in the config file will allow it to do 10 MHz. I added some extra heat sinking to ensure the temperature was reduced as it gets quite warm.

The best software is SDR# plus add-on plug-ins from rtl-sdr.ru which allow for extended recording times and playback.
If you cannot get hold of the an Airspy - consider an SDRPlay RSP1A. It will give you 8 MHz bandwidth - or 7.2 MHz usable - and also covers LF/LW/MW/HF. Then rather than use their SDRUNo find a copy of SDR# build 1361 with the necessary add-ons - as that will give more functionality. SDR# with Virtual Audio cable to feed RDSSpy software gives a very sensitive RDS decoding operation.
Also the SDRPlay works very well with QT-DAB - better than Airspy for weak MUXes next to strong MUXes.
Personally I'd buy either the Mini or the RSP1A as they are relatively cheap - then in a few months time Airspy could be releasing a new version with a higher resolution ADC and better dynamic range.
I actually have the Airspy mini and an original SDR Play and use both extensively - recording from both at the same time to USB .0 hard drives. I finished checking the last recording from the 2017 Es season in March 2018
