It has more to do with the power delivery to the active devices, whether they be tubes or transistors. A component can seem very detailed but not dynamic if the HF power delivery is good, but the LF power delivery is insufficient. Likewise, the component can seem very dynamic, but not render the detail if the LF power delivery is good, but not the HF. Detail is also a result of proper handling of return and power currents in the amp. If the currents are shared and generally uncontrolled, then the detail can be lost.
