Hi @atmasphere,
Thanks for your comment, but I am pretty sure I understand current and how it relates to solid state amplifiers performance characteristics. Sorry, but the article you refer to is so poorly written as to escape making any sense to me, hats off to you if you can understand the techno babble, with a bit of some kind of marketing. I am familiar with ohms law.
In the 70’s the power measures of peak watts and then RMS watts were shown to be grossly inadequate. This is when current came into the discussion. This is also when the first high current designed amplifiers were created. The first was the Threshold s series. I purchased the s500 after amp after amp failed to adequately power my speakers. The s500 would produce over 2.5 amps into 8 ohms and much more into lesser resistance. My next amp was a Pass x350 which would develop over 5.5 amps. This I found very amazing as I used an arc welder that produced 6 amps on constructing steel prototypes for work in the mid seventies. Anyway, through these and other high current amps I have used over the decades showed it to be a very positive guide to the solidity and resilience of solid state amplifiers.
