Hello all, I am new the forum and to minidiscs. Anyway, I have decided to purchase one of the newer Sony HI-MD models. However, in reading the product descriptions I am left confused about one thing... Some models, such as the MZ-RH1, will state that the output line will be: 1/8" 'headphone jack' and 'line'. Where as a model such as the MZ-M100 will state that the output is just: 1/8" 'headphone jack'. How come some models have the 'line' out feature and others do not? For whatever its worth, I plan on using the device to listen to both headphones and hook up to my stereo as well. So should I stay away from the models that just list 'headphone' on the output? Now, if there is a difference of any kind, PLEASE let me know, I am very picky about my sound and would probably be able to tell. thanks guys, r
