Your SCA-35 can power even Vandy's for a while, as long as you don't play it too loud. Tube amps are kinder to speakers ( and ears ) as they approach their power limits than transistors, by the way, since they clip more gently.
The Jolida integrated is a good amp. I don't know how well it compares to your Dyna. But your Dyna is really not bad-sounding, as I said above, and it makes sense to spend money on something that is sure to be a real step up. I have heard the two tube integrateds I suggest above, and I recommend tham.
But if you've decided on speakers for now, then wait and get used to their sound a bit, before you make a decision on a new amp.
