The general feel and design approach I see from the Tektons is that they are kind of like oldschool Klipsch in their target audience. They'll probably achieve a higher dynamic range than your other options, which vinyl typically has high dynamic range which is why so many folks out their use high efficiency speakers paired with tube amplifiers for vinyl playback. If vinyl is the primary function I would think the Tektons would do well in that pairing.
Just so it's understood I've never even heard of the brand until today when I started to read this thread, but based on what I've read and see on paper they might well be what you're after. They probably will be far from analytical, they aren't the prettiest, they won't offer the highest fidelity for your dollar, but I think you'll probably have fun listening to them, especially at high output.
