Tube amp with SS like bass

I don't know about the Rogue 90...my Rogue 120 Magnums (Kt-88's) have Krell like bass...as a matter of fact they replaced a Krell Kav-500.

That said, no amp can drive speakers which require more power than that amp can provide...no exceptions.

Your speakers, room, and SPL's required will be a big factor in determining bass impact...you didn't mention any of that.

I agree with Raquel, I auditioned several amps including the Rogues and ended up buying the Sonic Frontiers Power 2. There are lots above your price range, but in it, the Power 2 is your best option.

Of the ones you mentioned the Butler would be my pick. I heard it at RMAF and thought the bass was very good. It is a hybrid design and OTL, no output transformers.

That being said I would generally agree with the others who indicated you will have to set your budget higher to attain the goal.

audio by van alstine has hybrid amps with the most expensive being $1800 and in the 200 watt range.
