Tube amps will be as good a match as the tubes used. If you go with a tube amp, should account for that extra cost of tubes rolling. Unless the tube amp comes with a decent stock pairing, which are usually sold as an upgrade option.
Transformer coupled tube amps usually handle better lower loads, although some OTL are perfectly capable of driving lower loads like the ~60 Ohm Clear without muddling the sound.
Another option would be a hybrid amp. Like the Schiit Mjolnir 2 which you have?
In either case, tubes are the key. Did you roll tubes on the Mjolnir 2?
I've the Mjolnir Mk1, sounds really good with my og Clear, I would imagine the Mjolnir 2 with some killer tubes for the Clear should be as good as it gets really.
There are solid state amps that have tube like sound, like Audio-gd amps.
