AVI's new floorstanders and subs or three way in two boxes (part II)

Three or four hundred on transients, probably, - the power comes from the psu reservoir, not the mains fuse.

Transient performance is critical to accurate undistorted HiFi, - music is a low average power waveform, only a few watts are necessary except for the transients.

RMS is not a very useful measure of amplifier performance. Who listens to 1kHz sine waves. It's a legacy rating from the days of low power valve amps when 5 watts RMS was a lot :)

Thats still not an answer JC's. As mentioned there must be a test/spec report that exists, they'll have to have been approved to a British trading and manufacturing standard.
 
Look at the tiny fins on these things. Not much heat made by those regulators then. Mind you who measures heat in °C of °F or even Kelvin these days? Its a legacy measuring system when we used mercury and thermometers and deep space infra-red spectroscopy. We need a whole new measuring criteria for AVI based on Imagination... and Sugar Intake!...
 
Theres only 4 high current output devices per speaker, so will have its limits.


That's an interesting concept, Raj.

Ideally an amplifier would have only one final output device per channel, in a single ended design, or two for conventional AB designs (+ - swing about center zero).

That way linearity is optimised and distortion minimised. The problem is one of cost essentially. Very high power devices cost a lot of money, so most manufactures use several cheaper devices, essentially operating in parallel. Sometimes up to a dozen of them. This is a very bad idea, but necessary with older designs which have a limited choice of output devices.

The problem is making the multi output devices load-share properly, and the necessary circuitry to do this causes added distortion, reduced linearity, and much complication which is avoidable in newer designs, with newer final p.a. output configuration.

You're right.

It's probably that Ash won't show it to you though, because of your forum attitude.

jmo.

They are 1000 times better than ATCs - fact.
 
How much would you estimate the cost differences to be for the output devices £10-20? So if a company were to use say 12 of the best output devices in one speaker, what do you think the results would be?
 
I can tell you, having heard the pre-production prototypes, that they go VERY LOUD INDEED, without distorting.

Ash says the production ones are even better, but only he has heard them so far.

Martin assembled them yesterday, and is running the spec tests tomorrow, afaiu.

That's a poor use of deflection to justify not putting information in the public domain that Ashley would prefer to be kept secret.

What you are saying is the information will not be provided for public consumption because the wrong person asked for it.

Or it could be that the spec isn't that promising... lets see the proof!
 
JC, Hundreds of people want to see it. It doesn't matter to me, i don't want a pair!

Ahh, - right :rolleyes:

You shown an uncommon amount of interest, as well as expending very many posts slagging-off Ash and AVI, then :D

JC


p.s. you're not alone of course, there seems to be a nest of vipers on this forum. (just a very voluble few, - not everybody ;) )

Not at all, Steven, - you're construction is putting words into my mouth, which are of your choosing, seemingly for you're own contentious purpose.

The specs are available if you know where to look.

It would seem here that there is a fanbase of one and even he wants to use his own DAC.

The issue is not with the product but with the way it is (mis)sold.
 
Hey, i call a spade a spade, You both call a spade a digger. Don't BS, be subversive or ignore questions and you won't get anyones back up - simple really.
 
This thread has turned into a witch hunt, deliberately so, by some readily identifiable characters (the usual suspects), it isn't pretty, and it's obvious.
