Been hooked on single ended amps and high efficient speakers since the early 90s. Started with lowther drivers and 300B amps. Evolved to present system. Still miss the immediacy, coherency and transparency of midrange of the lowther drivers.

Would be upgrading to the Avantgarde Acoustic Duo Grosso shortly because I feel that midrange horn of the Picco can only go down to 290Hz. Prefer the Duo as the midrange horn goes down lower to 170Hz.

Will also be auditioning the Wavac MD-805m and Wavac MD-300Bm with my present system shortly.
