System Goals/Comments: Listener priorities: Emotional expression coupled with a non-fatiguing presentation. My objective is to capture a delicate, airy, dimensional presentation that suggests music rather than mere sound while exploring both nuance and tone.
System Strengths: The ability to reduce the listener's awareness of electronic artifacts with a cohesive, transparent and non-fatigueing investigation of nuance. UPDATE: See 'HomePage/URL' link.
System Weaknesses: Headroom. I continue to explore a 'proper' speaker for the Moth but after 4 years haven't found anything that quite satisfies as well as the Sonatina / Moth combo. It's not perfect but for my situation it's more than a comfortable spot to rest on the journey.
