Classe'25 with Maggie 1.6 is a great combo. The 25 can produce up to 500 wpc into the 1.6's 4ohm load. So the result is very dynamic with great bass drive. You don't really need a subwoofer with this combination. Some folks find the 1.6 to need the resistor to tone down the tweeter. Not so with the Classe' 25. I never felt that the 1.6's high frequencies too aggressive driven by the 25. The 25 is very musical as well as muscular. it throws a great soundfield and the harmonic structure of musical instruments is well preserved with the Maggies. It did not do as well when I upgraded to the 3.6 but I thought it was terrific with the 1.6. Its frequency response was very complementary to the 1.6. Overall coherence with the 1.6 was excellent. However, with the 3.6 it aggravated the different speaker elements and produced a discontinuous effect. If fact, with the 25 driving the 3.6 I did need to pad the tweeter with a 1 ohm resistor. In conclusion, in my system in my room, the 25 was wonderful with the 1.6 but not so good with the 3.6.
