I have been seriously considering outsourcing an entire system to upgrade, but I do not know where to go from what I currently have. I am running a Sansui AU-919, Sansui SE-7, Sansui TU-717, and a pair of MINT condition JBL L80T's that have recently been re-foamed to perfection. I feel like the only way to move up from a MINT upgraded Sansui AU-919 would be to move into the Tube world. I am open to any suggestions. I would be forced to sell the Sansui pieces to upgrade to something else based on a financial situation. I do not feel like I will ever part with the speakers, so I feel like if I were to sell all 3 of the Sansui's with their handles i'm looking at a 1300$ budget at best. Is there anything even in that price range that could be considered in the same zip code as the AU-919. Or did I just catch the audio bug. I would consider investing up to 2000$ on a decent tube amp if anyone knows of a great one at that price.
