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.
The Cary 300B amp is more intimate and forward sounding. The 211 amp is more dynamic and have a bigger soundstage but not as intimate. My ideal amp is one which has the best of both worlds - one which is dynamic and has a huge soundstage but does not sound laid back and with intimate midrange.
I listen mostly to vocals and instrumentals. Occasionally I also listen to classical. The type of sound that I try to achieve is one with a wide soundstage and effortless immediacy and dynamics.
I did not graduate from the PC-1. I jumped right into the PC-1 Supreme. Sorry I could not offer any thoughts on the differences between a PC-1 Supreme and PC-1. But I have ordered a DaVinci Grandezza arm. Will update on the system once it is fitted.
