Most SETs employ DHT (Directly Heated Triodes) like the 300b, 845 and 2A3.
DHTs can be used in push-pull as well.
If you want more than about 10 watts, IMO/IME you are far better off with a push-pull amplifier, and in your case with your speakers you will be needing more than that unless you are listening from only a few feet in a small room. If in an average room 60 watts will be a good power rating if your speakers are 94db.
The impedance of the speaker makes a difference too; generally speaking you will get better performance out of any tube amp if the impedance of the speaker is 8 ohms or higher as opposed to 4 ohms.
Balanced operation can be very helpful! If you have monoblocks this will allow you to run shorter speaker cables which will win you greater impact and definition. You can run longer lengths of interconnect cables if they are balanced, and if the preamp supports the balanced line standard (be forewarned- most high end audio preamps do not) the length of the cable and how expensive it is will have little impact on how it sounds. BTW there are balanced line tube preamps that support the balanced standard- we make one example (which also happens to be the descendant of the first balanced line preamp made).
Good Luck with the Quest.
