For you 125 owners out there...a few questions: 1) Does this unit not feature an adjustable crossover? I could not find anything about it in the OM. 2) This is a weird one - has anyone noticed that the display for the unit is the same as those on higher models (for example if you look upclose you can see the ES for dts es even though this unit does not feature it). 3) The 125 does not have onboard MP3 decoding right? Anyway, for those that do...like the 325, how do you go about using it? I have a turtle beach santa cruz which outputs the digital signal out the right channel of its versajack. Currently if I open up winamp and play something, I'm sure winamp decodes the mp3 and sends the decoded signal out to the receiver to be played. What software do people use to send the pure mp3 TO BE DECODED by the receiver? Is there significant improvement of the sound by letting the HK do the decoding vs the software?
