It’s a matter of preference, room response, system character, and the bass in the recording. Ideally, it’s good for the system to reveal differences between recordings as opposed to having a constant bass characteristic/coloration, but nothing is perfect and many things can affect what’s heard.
My smallish Dynaco 70 tube amps tend to have a softer bass bloom rather than an impactful tight slam and extension, but it was often on the pleasant side, depending on the recording. Adding the VTA mods helped, but the best solution I’ve achieved for good bass with my room and system is to bi-amp with a solid state amp to the woofers for low bass (below ~65hz), and tubes from the lower mids (lowest vocal range) and up. Best of both worlds.
