This one is magdalenae x sesquipedale. This is a great hybrid from your photos, with flowers standing in good position and with a long spur and fantastic scent.
I have no personal experience (only one giryamae), but a friend of mine is very much into these plants for years. He says that in the first years seedlings grow slow, like they do in nature on branches. But after some years, when the roots have reached the ground, they grow much stronger.
Also many plants from the interior of Madagascar come from higher altitudes, where night temps can drop to 12-15°C. So many angraecoid species in his collection grow better in his cooler house.
Angraecum magdalenae is a species growing inlands at 800-2000 meters on rocks.
