Donald revealed that he feels the group are currently at the top of their game, but always like to improve things for their fans, after impressing them on current jaunt 'Progress'.
"We're at the highest possible point we can be tour-wise and album-wise. We've done much better than I expected. It would be complete sacrilege if we said, 'Let's call it a day, let's stop'," he told The Sun.
"We could stand on a massive stage and put amazing lights and lasers on and not have any of these tricks and hydraulics and the big men and elephants. We could have all that and we could do a great show.
"But would they ever come and see us again because we are not of a standard that we were in our last show? We want people to go home and go to sleep with a smile on their face, be blown away by it and hope a Take That ticket goes on sale again in a couple of years."
Speaking of recording the band's latest album Progressed in New York, Donald added that he loved the creative process and could feel the strong bond that the five members have with each other.
Robbie Williams recently confessed that there will be "over-sentimentality and tears" when their current tour ends.
