Ex left me with 5.1 set up.. 'not womens stuff':f so didnt let me watch the setup. Had to do DIY and had to move set up.. now only getting 2.1 on audio playback, also sound is really 'tinny' now. Think Amp is on way out. Been looking for replacement but its a mine field for the 'uneducated' so would like some 'layman' advice. Was looking at STR-DH510 but not sure speaker connection is compatible.. Does anyone know if i can change to this amp? Concerned about bare wire connection, over jack plug. Probably asking a really dumb question but can you change bare wire to jack? Have HDMI tv and HD hardrive DVD/freeview box and want to get optimum sound back again.. i miss my music so much Cant hook up HDMI to this amp everything going through scart. Will be so grateful if someone can answer all of the above and give some advice.
