Lately I’ve been running two sets of maggies with two different amps coming out of one DAC. A Stellar S300 and a Forte 1A. Class D (with the unique input stage) and pure Class A. I inserted a passive pot before the Stellar, allowing me to adjust the mix.
Observations: The Class D is better for piano (more impact), the Class A is better for violin (more sweetness). And it’s the best of both worlds for violin sonatas and concertos. For horns and other wind instruments, both amps are equally good.
I’ve heard it said that SETs are best for very small works, a jazz trio or solo female vocals or solo guitar, but not for complex orchestration. Makes me wonder if certain systems are optimal for certain types of music or certain instruments. Not long ago I heard a Wilson demo, and the guy running the show played some small-scale work like folk music on it and it just sounded ridiculous and heavy. I thought something that I’ve seen in reviews from time to time: “This would be great for Mahler.” (Mahler isn’t my thing.)
In sum, consider the possibility of biamping with Class D and Class A.
