I bought the Denon dvd-1910 on a whim yesterday on the classifieds and have a question regarding dynamic range. In the pdf manual it says the denon has a cd audio dynamic range of 98 db, so does dvd video usually provide greater dynamic range.
I have at present a Toshiba SD-520E dvd player which the manual says has an audio dynamic range of 108db. Is this a big noticable difference?
I'm concerned now that the Denon may not give me as much audio satisfaction as the Toshiba.
Any thoughts please?
