Yes. I bought a NAD D3020. I was using Marantz PM6004 with Wharfedle diamond 9.5.
Last year I relocated and I had to leave my setup behind.
Now I have NADD3020 paired up with WharfeDale Evo 2-8
NADD3020 gives excellent connectivity options with Bluetooth and USB DAC. It sounds good but it is not better than marantz. I feel it is a little underpowered. It never distorts .
The remote is good looking and is works well.
I have seen excellent reviews of NAD D3020 and to some extent it does justify the good reviews and it sounds decent enough. May be it will sound good with a better pair of speakers like Tannoy Mercury or Dali Zensors.
Overall I was more satisfied with marantz PM6004.
May be you can check out Marantz PM6005 that has a digital input.
But again, listen to it before buying.
