There is information in the internet mentioning that sansui AU 777(non A) follows very close and similar design to the sansui AU 111 tube amplifier, I am not very sure but both are very good amplifier to be own.
I think you wont be wrong getting the one with A or basic 777. I love my AU 777 but i have no compare with the 777A before because this amplifier are very rare in my country. One of my friend had the 777A and he said that it has a little bit more advantage in low frequency compare to the AU 777.
Wally,
Congrats, i wish to hear a fully original untouched Sansui AU 777 to compare with my recapped unit. Have you try the unit and compare with the AU 777A?
Wally,
Great to hear that you have been to Malaysia. AU 777A is very rare amplifier here in my country, only AU 777 is easier to be found and i have come by with 3 units. The other two is with my cousins who really love how it sounds and one of them is having it fixed with an B&W...
Hi Quadklpsh,
Are you saying that the cost design spend by Sansui only for the power amplifier part for this amplifier? I don't think so, the preamp should be well design like other sansui amplifier.
