None of the early symphonies were heard by Schubert (or anyone else) during his lifetime, which is tragedy enough. Yet they have real eloquence, including plenty of lyric and dramatic elements worthy of Schubert's genius. Heras-Casado and the Freiburger organization give the music stateliness and stature as called for, passion in good measure and well-balanced directness consistently. They neither over- nor underplay them but find the right balance for each.
These are versions that have the ring of authenticity. I still have several on vinyl, some well-regarded at the time of their release, but they do not satisfy me as these versions do. I hope Heras-Casado and the Freiburger Barockorchester go on to do the whole cycle. They seem perfectly suited to bring out the brilliance of the younger Schubert and I'll bet would give us insightful readings of the later symphonies as well.
