Olympicas will scale with better equipment. I heard the Sonettos a few months ago. Not bad for HT or mix usage. But when the dealer played the Olympica Nova ii with higher end ARC amplification there was no contest. The Olympicas are more refined and much better at reproducing the sound of natural organs and instruments like piano, violin, horns, and guitars. I ended up buying the Olympica II but will most likely go up the line next year.
By the way, the Olympicas love class A amplification.
