RX888 vs Perseus receiver test

I compared RX888 and Perseus in the same time with the same antenna. In night time listening the difference is not so clear. One can argue that RX888 is slightly behind in sensitivity. However, in morning during daytime listening RX888 cannot compete. In spite of in-built amplifier both the sensitivity and dynamics are lacking. Especially clear this is in the case of Utvarp Föröya 531 kHz.
