High Current vs high power

I, of course, agree with all of Ralph's (Atmasphere's) well stated points. I would just add that the miniscule amount of time for which a "high current" amp can provide large amounts of current into a dead short (10 milliseconds, or 1/100th of a second in his example), is generally not stated when maximum current specifications are presented. Which makes the 50 ampere or 80 ampere or 100 ampere kinds of numbers that may be presented for some amplifiers even more meaningless, because chances are those numbers for different amplifiers are based on different amounts of time.

The signal going into a power amp is usually high voltage and low current. The amp reverses this to low voltage and high current.

Alan, based on your posts I've seen in the past I suspect that you are sufficiently knowledgeable that you must have composed this statement before having your morning coffee. The voltage-related parts of it, that is. :-)

Al and Ralph, it amazes me how this technical issue just keeps on giving.

I think the whole subject could be mooted if every speaker on the market was required to have an 8 ohm ruler flat impedance curve and zero phase angle curve as a function of frequency response. That way all speakers would be tube and SS friendly.

Well, I also believe in the Tooth Fairy and Ariel the Little Mermaid so anything is possible.

To the other guys -- please don't take this post as a put-down. This issue has had me bogged down for over a year now. So count me in as a card carrying member of the confused society, but just a little bit less so today thanks to Al and Ralph. Just check my other posts.

I don't see why any of this can be so confusing. If you take the technical info, such as Al and Atmasphere have provided, and suppliment it by listening to different combinations of amps and speakers, it should all fall into place. Picking audio components is mostly subjective. You can't bypass listening and hope to be successful. You can get sound to come out of just about anyting, but for good sound, only you can decide.

^^ Yes, audiophiles have seen those pesky spec sheets for amplifiers for decades, but so little on them tells us what is going to sound right that you still have to do the audition. More fodder for the objectivist/subjectivist debate...

Have a Rowland 8T has both over 250 CH plus High Currant i have both.
