First, it is true that you don't need a ton of power, but there are relatively few Hi-Fi amps that are more than stable at 2 ohms and few thrive at such a low impedance. Either auto or pro audio might have decent options as they tend to run at lower impedances.
Second, as someone who has owned speakers with a 1.7ohm minimum impedance, they are a giant pain. I had the original Infinity Kappa 8.1s which were notoriously miserable to drive. There are not many amps that are happy at a nominal impedance of 2 ohms, and definitely not in that price range. Certainly, you will never drive them with a tube amp.
The Naim NAP 300 DR is one I can think of that is fine at 2 ohms for extended periods but that is a $14K amp. Not sure I can think of many others. If I bought those, I would buy a big bag of fuses to go with them unless I had just the right amp.
