They replaced a Levinson 333, and in my system they are about as good as it gets for me.My speakers are Shahinian Hawks, I believe 89db and they drive them with ease (4 ohms as I recall but don't quote me), ARC pre, PS DAC/Transport, Magnum Dynalab 809 Internet Tuner and PS P12. Minor tweaks to power cords and thats it. Blows away the Levinson, again, in my system
