This is not a simple question; the damping factor should be high enough to control the movement of the woofer; if it is not then it will exhibit "loose" uncontrolled bass rather than "tight" bass. There are many factors that determine what is "enough" damping factor, the design of the amp, the design of the speakers, their interaction etc. Transistors typically have a much higher damping factor than tube amps, many find them "tighter" others find tube bass "more natural". The best answer is that there very good amps with a high damping factor and very good ones with a lower one. The whole thing comes down to system matching, it has to be high enough to make YOUR system work, that will vary in every case.
Amplifiers and Damping Factor
Is higher damping factor more desirable than lower damping factor?
If an amp has a higher damping factor does that mute or control the bass output of a given speaker? Sort of like "reigning in" the bass.
How critical to the bass output potential of a speaker is amplifier damping factor?
If you prefer more bass rather than less, what damping factor range should you look for in an amplifier?
