Dear all AV Forums friends ! Anyone tried Surround Amp Front-L/R pre-out to Tube Amp aux-in when watching movie ?! I owned a Marantz SR7000 Surround Receiver, and a Houston Mini-2 Tube Amp. Will I gain any benefit (in sound quality), when connecting the Surround Receiver's Front-Left/Right channels pre-out to the Tube Amp aux-in ? (note : my Tube Amp do NOT has any power-in or processor-in, just ordinary aux-in, cd-in) i.e. the signal path will then be :- DVD Player (Philips 963SA) digital-audio-output ===> Surround Receiver (Marantz SR7000) Front-L/R pre-out ===> Tube Amp ===> Front-L/R speaker (KEF Q50) --- of course, the remained channels (Center & Rear) will still be driven by the Marantz. Will the above idea improve the overall sound quality ??!
