I've got to test both the Sony XDR-S60BDP and the Panasonic RF-D10. Both of them are nice DAB+ radio's with their own pro's and cons.
First off, sound quality. The Sony didn't really convince me in terms of sound clarity, as it clearly lacked both treble and bass production. There are no settings to adjust that. The Sony sounds to me like a pocket FM-radio, but in a much bigger housing. Given the size of the unit not really the sound you would expect. The Panasonic on the other hand sounds clearer and has more power/louder output, even on batteries. There are options to change the sound by selecting a pre-defined EQ setting. 'Heavy' has the most treble and bass, and this way it sounds very rich in comparison to the Sony. A win for the Panasonic here.
In terms of design I give credit to Sony for the nice design elements they used. It combines a retro look with a modern and fresh appearance. The Panasonic does not look bad by any means, but I like the Sony better on this one.
The build quality from both is what you would expect of electronics fabricated in the last couple of years, reasonable but noticeable cost saving elements. The Sony has the best finish in my opinion, and does not look cheap at all. The only downside is the light glossy plastic housing, which seems a bit scratch sensitive. I was able to put some marks on it that wouldn't go away with my fingernails. The Panasonic uses a slightly more rugged type of plastic, and does not scratch so easily as the Sony. Or at least it is not that visible.
While using these the Sony has a more intuitive user interface, mainly because the display has four rows of text. This makes browsing channels and the menu itself very easy. The Panasonic on the other hand has just two lines, and only the lower line is used to browse channels or navigating through the menu. This way it takes a little longer to find what you are looking for, but you will get used to it.
The reception quality is equal on both units, I've never had any drops or hiccups whilst listening to DAB+ stations, but this varies from location to location of course. When pushing the reception strength to its limits (antenna not pulled out) the Panasonic manages to get a tiny bit more reception than the Sony, but this difference is too small and inconsistent to say the Panasonic has better reception.
There are some design elements that can raise questions, like the power (AC) input on the Panasonic is at the left side on the upper half of the unit, so it is very visible and it takes away the neat look. On the other hand this is made up by the fact that the Panasonic has a carrying handle that can be rotated up and down.
In the end you normally buy a radio to listen to, so the sound quality has made me choose the Panasonic over the Sony. I am very pleased with it and can highly recommend it.
