I was just speaking to OP’s criteria, but FWIW -- INT-250 produces a broad and deep soundstage. I mostly listen to classical and acoustic jazz. This amp puts me center loge Orchestra Hall, Chicago. Absolutely brilliant. Bass you can feel in your sternum. Dimensional sound.
The added bonus is that Kent at PASS is just a delight to deal with should you ever have any questions.
