I have two systems, an Accuton based system and a Phy km30-based system. The Accutons are driven by 300 watts tube-hybrid in a large room. The Phy are driven by 10 Watt 300B in a smaller room. The speakers are by Marten Design and Musical Affairs respectively. I listen mainly to jazz and rock.
The Martens excel with all music types, but especially complex music and amplified music (ie. rock, electronica). They are crystal clear, and provide the necessary quickness and slam. I find them neutral in character.
The Musical Affairs are lovely with vocals and acoustic ensembles (small group jazz, chamber music), and some older classic rock recordings. They provide warm full tones and timbres, and surprisingly deep and tuneful bass. However they do not do well with modern (ie. loud/compressed) recordings of rock and electronica. With these musics the rendering is often flat and lifeless. Also they do not compete at the high frequencies with the full-range designs.
This is a classic matchup of medium sensensitivity multidriver versus high sensitivity full-range driver. They are both excellent designs, but quite different in my experience. In the future I hope to compare my Musical Affairs to Horning's Eufrodite.
