Hello.. I just got two amps from an old friend's basement. He told me these belong to previous owner who never came back for left overs. God is great. My friend didn't hesitate while i intended to pick these. Amps were in protection mode. First was Sansui AU-D707X which is a japanese version of G90X. Second amp is bit confusing. Its D907x also japanese domestic 100 volt model with massive 160wpc. Now the big question. Which amp should i keep for restoration. Coz this 707x is closer to D11ii and 907X uses different power transistors (found in D9, D11 and G99x as per my limited knowledge). The problem is.... Ill have to keep only one. So i need suggestions from you guys... BTW i loved the sonic signature of D11ii and G90x (both at another friend's place who is insane sansui lover). Recommendations must carry weight. Thanks.
