I think your epos speakers are good, I would change the amp! I worked my way up the integrated chain owning:Rotel,Arcam,Rega,and Bryston. Bryston is my favorite, but I really loved the sound of my Rega Brio.(if you don't need a remote or a ton of power!) I think a used Mira would be a great choice too. Sometimes you can find Bryston-B60's here on A'gon for about $1000, and have at least 10 years of warranty left.(great amp!) I have also heard my friends PrimaLuna, which is what I would buy if I was getting into tubes. Good Luck!
