The Sangean PR-D5 is a great radio for a reasonable price. Yes, it can be discibed as muffled when compared with others, but this is not always a bad thing. I find some long distance signals benefit from having the highs trimmed off, particularly when listening for a longer session.
I do like the PR-D5 for listening to my favourite JAZZ-FM from Toronto. It can be difficult to get a good signal in my location and on FM I find the muffling less noticeable.
I think that among we radiophiles we may be perceived as splitting hairs by more casual users. I select from several (many?) radios for my listening and , really, how much of a difference are we talking about? Right now I am listening to 650 WSM from Nashville. They are airing a songwriter show with a combination of talk and music. I find the talk much clearer on my SR1, but the PR-D5 is more pleasant when they play a song. Both have strong, steady, and clear signals. A great attraction of the PR-D5 is the digital tuning. I must admit that when MW DXing I often use the PR-D5 as a "targeting" unit and then tune in the SR1, EP, RF-1115, etc... to pull out a clearer weak signal.
I also use it to listen to music podcasts, though, admittedly, I prefer the EP for listening to spoken word podcasts. Isn't it great to have this luxury of choice and the leisure to make such comparisons?
