High Current vs high power


Hi!

Often you hear/read comments that the current matter more than the power (example Nait) and one should look for high current more than high power etc.?

Can anyone explain that or debunk the myth (my limited physics knowledge tells me that power and current are interrelated for the same voltage and impedance)?

Also, which amplifiers (pre power or Integrated) have 'higher current' than their peers at same power ratings? Is there any specification that shows the current capability of the amp which one can read and compare? like power, THD etc.?

Thanks

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...
Zd ... more than you know, I agree with what you said about live auditions. A while back, I posted a comment about road testing two sets of speakers at a dealer friend's shop. Coincidentally, he had just taken in trade an ARC VS-115 tube amp, which until a week ago was the amp I used. That's about as good as it gets for "A/B'ing" speakers. I was quite surprised that a speaker similar to my current fronts ("Brand P") cleaned the floor up with Brand X. Was it the gear, the room, the cables, the amp??? Dunno. But in "theory" Brand X should have cleaned up the floor with Brand P. Go figure.

But here's the dilemma. How often can one fairly audition speakers, amps and other gear given the paucity of high end B&M stores? Forget being able to control all the variables, like using the same model amp when comparing speakers. At least in my neck of the woods, forget taking gear home. Doesn't happen.

OTOH, I find the subject of speaker/amp electrical compatibility interesting. Grasping the variables, many of which are EE design trade-offs, is challenging. But that's me.
