@gregjacob Something you want to consider before moving ahead blindly with an SET purchase is the difference between sensitivity and efficiency. Sensitivity is a voltage measurement (2.83V @ 1 meter); efficiency is a power measurement (1 Watt @ 1 meter).
If the speaker is 8 Ohms these two are the same since 2.83V into an 8 Ohm load is 1 Watt. Your speakers are a lower impedance than that; hence they are not as efficient as you think they are. You did not mention which Daedalus. If a 6 Ohm model subtract 1.5dB from the sensitivity measurement to arrive at the efficiency. If 4 Ohms subtract 3 dB since 2.83 Volts into 4 Ohms is 2 Watts, not 1, a 3dB difference.
Now the sensitivity measurement came into vogue in the 1970s when solid state amps became really common. Most solid state amps can behave as a 'voltage source', which is to say they can double power as the speaker load is cut in half (although a cheap one may not be able to do this at full power if limited by its power supply). OTOH, tube amps don't do this at all- in particular SETs. For tube amps in general, the efficiency spec is more useful on this account. If a tube amp is able to act as a voltage source, it will employ feedback (SETs usually do not) and will cut power in half as impedance is doubled rather than doubling power as impedance is halved. This makes tube power really expensive.
A further complication is you are talking about an SET. SETs have about 20-25% of usable power. Above that power level, even though they are not clipping, the higher ordered harmonics start to show up in their distortion. The ear uses the higher ordered harmonics to sense sound pressure. The result is they start to sound 'dynamic' since the power used in music is mostly on transients and now you are getting loudness cues on the transients (that are artificially generated)! This is why so many people talk about the 'dynamic' nature of SETs. They are misusing the amplifier by having a speaker that lacks efficiency.
The bottom line here is that unless your room is very small using an SET on your speakers is a Bad Idea. Quite simply you'll need more power. One other thing- SETs have trouble making bandwidth due to output transformer limitations. Effectively this means that to get hifi bandwidth the amp probably should not make over 7-8 Watts. Add to that the problem of usable power and you can see that 2-3 Watt isn't going to make it in most rooms with speakers like yours!! A more powerful SET will lack bandwidth and the typical way of doing that is to compromise bass bandwidth in favor of the higher octaves (IOW its a design consideration the designer has to face).
This does not mean that you have to leave any musicality on the table when going with another kind of amplifier! There are push pull tube amps that have the same kind of 'magic' of SETs and now there are even class D amplifiers about which the same can be said.
FWIW I have speakers that are genuinely 98dB efficient and I find I need at least 40-50 Watts and my room is a bit on the small side. I don't use all that power of course, but it does mean that the amplifier is loafing and as a result distortion is very low- this results in greater transparency (distortion obscures detail just so you know- you do pay a price for higher distortion amps like SETs!). Of course we all want the relaxed liquid mids and highs that SETs are known for but seriously that's no problem for other kinds of amps as I said. And there are those occasions where the system really has to use some power- such as playing the Saint-Seans Organ Symphony at a proper level and doing it without strain.
So if you really don't want to go down a rabbit hole and flushing dollars down the loo at the same time, IMO/IME avoid SETs with your speakers, unless you are in a very small room.
