Have you ever heard the Magicos on a great tube amp?
Driven by CAT amps/pre, the Magico S5MKII is at the top of the heap of systems I've had some longer term exposure to (not just a few minutes at a show). Unbelievable clarity and dynamics.
Without being able to try speakers in your room, there's significant risk of getting an unintentional downgrade. What are you looking to improve upon?
