Is hybrid power amp the way to go ?

Hybrid amps ’could’ be the way to go, depending on the speakers, room size, listening levels, and personal tastes.

Obviously, there is a very large speaker market out there that SET tube amps just cannot satisfy. Not that SET amps can’t sound wonderful with the right speakers, however, SET’s do limit your speaker choices.
Someone has to make the amps to drive the speakers that SET amps can’t drive.

I think Hybrid amps may be a good path for those who wish to run direct from source, without a preamp.
For those who use tube preamps, I don't know that there is much to gain by using a hybrid amp.
