Post Subject: Harmonic development and SS gain pathsPosted by Paul S on: 5/1/2008

My recent "success" with SS is limited to sources, where I am +/- satisfied with the results in terms of harmonic development; I feel like I am close enough, if I attend to amps and speakers, etc.

But SS amps have been another matter for me, and I have not yet heard a SS amp that did not exhibit a strange harmonic signature and stranger "texture" - rather, the lack of it, along with what sounds to me like a "too-abrupt" on/off cycle, like a pot that "jumps".  Is this a matter of the voltages involved, or what?

I wonder about the sources of these anomalies, if they inhere in the devices or are artifacts of the circuit configurations, and I have been curious to experiment to see if JFETs and/or high grade op amps could be used to get SS benefits in a +/- powerful amp without the weird harmonics and "texture" and "jumping" I have come to associate with SS amps.

Do others still hear these things with SS, or is all this part of the past?
