I was told today that Emotivas are not "Hi Fi" amplifiers, please is there any kind of "official" definition for a what a "hi fi" amp is ?
Whoever told you that seems like he doesn't much understand what makes an amplifier work. Amps are relatively easy things to design and their problems have been solved for decades now. This means that all decent (of the sort we'd consider using as AVS members) solid state amps, working within their design parameters and not driven into clipping, are sonically indistinguishable in properly conducted blind ABX tests.
In the days before I understood these things, when I was an 'audiofool', I let 'high end' dealers and magazine reviewers talk me into spending many tens of thousands of dollars, cumulatively, on various exotic amps. That I kept feeling the need to change these vastly expensive amps should have been a warning bell. And eventually it was and I decided to start using my education to research the subject instead of blindly following all the hooey I was being fed by retailers and magazine reviewers.
The result, is that today I own 4 x Emotiva amplifiers and one Crown 'pro' amplifier and I am totally satisfied with them. A good amp takes a signal and reproduces it without changing anything except the loudness. Pretty much all of them do that these days.
If you want to read some of the results of some of the blind tests that have been done, this is a good page to start on - it has links to a lot of interesting tests.
Not so much for the amps. More for their unfortunate efforts with prepros. I'd say that if you go to the AVS Emo forums (not the rabid fanboy Emotiva's own forums which are mostly pointless) the general impression amongst users is that they are good, reliable amps at terrific prices. Mine are used every day, and have been for years, and I've never had a moment's problem with them.
I have never heard such a ludicrous argument. Emotiva must have sold many thousands of amps (I have 4) and yet only Polk speakers are affected by their "pollution of the signal"? How likely do you think it is that of all the thousands of users of Emo amps, nobody has ever reported one, to my knowledge, as damaging their speakers (when used properly obviously) if this problem is widespread? The forums would be full of "Emotiva blew up my speakers" posts!
You need a can of this before you speak to them again.
True, but they didn't suggest it had been overdriven - just that the Emo amp is not a "hi-fi" amp. I’d love to know what their definition of a "hi-fi" amp is. I’d also love to see their spec sheets for the speakers where they tell you what kind of 'hi-fi' amps they are supposed to work with. Whoever they have on their support line would have been dismissed by now if he worked for me. Ludicrous doesn't even begin to cover it.
