Thank you for taking the time to further explain. Now I understand!
I've had SS integrateds that sounded lean/fatiguing and tube integrateds that sacrificed detail and bass focus for the sake of a "liquid" midrange. My current integrated is a Hegel H390 that has excellent bass control and much more detail than I've ever had (without fatigue) combined with a midrange that is (to my ears) natural sounding without the tubey "liquid' quality. More midrange bloom would be wonderful but the gear I've owned so far has inclined me to believe there are always trade-offs--emphasizing detail tends to risk ending up with fatiguing highs and pursuing a euphonic mid-range risks loss of bass control and resolution.
However, from what you've said, I gather AR avoids such compromises and "does it all". I may be able to afford used AR in time. Until then, I use a Schiit Lokius with my Hegel H390 and am quite content.
