Help need an integrated amp for Tannoy Stirling


I am currently using a Sansui AU-717 to amplify my Tannoy Prestige Stirling SE speakers. The sound is characterized by listener fatigue and is a little bit like a scream. Before these speakers, I had Totem Hawk and the sound was OK, maybe not a very full sound but very listenable and enjoyable. Before I listened almost always an analog source LENCO L 70 modified plint and now I like to listen to more cd because of that. I'm sad because I don't like the sound anymore.
The Tannoy I bought them new and now they have about 200 hrs. Any thoughts about these, or other amps using the Tannoy Stirling speakers?
Thank you very much,

Let them break in for another 200 hours and get a tube integrated amp which will ameliorate any "screaming." More break-in alone may help. What is your price point to purchase a different integrated and what are your other components -- cartridge cable, step up, etc?
Around 3000-3500$ for used integrated amp.
Cartridge is Micro Acoustics MA630 and the phonopreamp is Threshold FET 10/pc with Lustre GST-801 arm. Before these speakers I has the same configuration.
try a Viva audio Preciso or Solista LT is amazing with Tannoy prestige series.
