Well I own 3 SDR receivers. 1. SDR Play RSP2pro 2. SDR Play RSPdx, replacement for RSP2pro 3. AirSphy HF+ Each has its own advantages, but if your interest lies in 10 Khz to 30 Mhz it is no contest the AirSpy HF+ is the hands down winner. No question about it. If you interest lie outside that band, the SDR Play is a better choice as it covers a much broader frequency range. I do not have any vested interest in any of the products or favor any of them. I mostly listen to MW, HF, SWL, 2 meter, 70 cm, and broadcast FM. For those bands HF+ holds a big advantage. Those two extra bits in the A/D converter add up to 12 db more dynamic range in AM modes. That is extremely significant in terms of performance.
