Help with a first tube amp Please

I am looking to buy an amp.I have never heard a tube amp but I keep reading all the rave.Right now I have a Mac1900,Sansui Tu and Au 7900 and a couple Luxman recievers, all powering speakers as Sansui SP 1200, H H Scott from 1964 and ADS and a pair of newly purchased Magnepan mg2 for 75.00, that was a deal. I have a budget of up to 1000.00 tops.I don't think I want a Ying Yang amp from Ebay and I can't buy a vintage MC 275 either.I wiould like to buy an integrated amp to start with.Well thanks for your help from Rochester,Mn.
