pareho sir. actually hindi masyadong halata pagkakaiba.

kasi ang fet input opamp mataas ang impedance ng input

kaya hindi nakakaapekto sa filters.

1.audio out ng dvd mo  ikabit sa headphone maririnig mo ang audio nya(gamit ka ng adaptor ng bb-jack ng haedphone)
2. saksak mo dvd sa input ng konzert
3. gamit ka ng female jack para sa bb-jack ng haedphone. hinang mo yong ground ng female jack to ground ng konzert. yong isang terminal(signal) ng female jack dun mo ikabit yong tester probe mo, (ikaw na bahala pano mo ikabit)
4. paandarin ang dvd at konzert(make sure nakafull volume)
5. Yong tester probe mo ang lilipat from one test point mo to another.
6. umpisahan mo pakinggan(sa headphone) mula input ng konzert to preamp, to bass treable hanggang input cap ng amplifier
7. kung malinaw hanggang input cap ng amplifer then no way na hindi sya malinaw sa malaking speaker(assuming na ok ang amplifer)

good luck....
