Does not matter.
What does matter is that the tube amp be matched with speakers that the tube amp is capable of driving properly.
Also what matters is that if a tube preamp is used (higher output impedance) look for a power amp with higher input impedance as well to better mate with the tube pre-amp.
Results will be better dynamics and lower distortion, always a good thing.
Results may always sound "good". "good" is totally subjective. But by following these basic guidelines you can better cut to the chase and avoid discovering down the road that properly mated components work better together and hence almost always sound better as well.
