Hi there,

I think the ETF presentation by Lynn may shed some light on this.

http://www.nutshellhifi.com/library/ETF.html

Looking at the output loop of a conventional SE amplifier and combining this with hi vs low Zmax you could assume that the 'longer' path to ground with a larger cap between SE xformer and earth will affect performance more than let's say the parafeed arrangement with s small cap to ground handles the AC part of the signal....maybe why parafeed seem less sensitive to speakers than conventional SE. This of course not heard by me, only based on comment from the board.

The ETF presentation great for understanding the different topologies anyway...a must read???

PS Wayne. Planning the build of the Stage4, should happen in 2 weeks time...home alone one weekend:) no distractions.
