Amati Futura vs Guarneri Evolution

[A.Wayne]

I have never bi-amped a 2way only 3ways myself, i can only say and with all certainty , there is for sure one truism in audio and that is, everything makes a difference ...

Only one way to find out ...

Much greater change when done on a three way where one amp drives the woofer(s) and one the mids/tweeter.

Didn't say there would not be a difference - only that output capability and dynamic range changes would be small. Doesn't mean that other changes will be.

As you say, everything makes a difference.

The graphs presented was not about amplfier drive , it was my opinion on usable power vs rated power as they relate to sonics , the soulution distortion spectra lowers as it is driven harder , this tells me it will sound less natural than an amp which starts lower and flatens off or rises with driven output , This is how we hear sound in its natural state , This is also one criteria to looking at an amplifier sonic signature and does not tell the whole story .

My guess most will find the Dan amp more musical and natural sounding , but not necessarily so for all , as it is a very complex equation and we need to look at the whole picture and the soulution is rated at 130watts / ch at 8 ohm look at the distortion spectra at rated output vs the 33% sweet spot , you will see 33% still represents the best point when looking at its distortion spectra and my bet best for sonics ...

My conclusion you want to argue for argument sakes and revel in semantics.....

PS: I nor anyone else should need to own an SF speaker to discuss it , if there is such a criteria please let me know i would hate to violate SF ownership protocol ...

Now you are just getting rude.

As I said in my last post, I don't have a problem with you commenting on SF speakers, so it was churlish to raise that.

What is at issue is your theoretical predictions are at odds with my empirical experience. I was able to achieve a very satisfactory performance with a solid state amplifier with a substantially lower rating than the 500w that you predicted was necessary.

Perhaps I should leave it at that, because you don't seem to enjoy having your theoretical assumptions, and rather unusual views, challenged.

Hello Glisse,

You know i have the same feeling about your responses being rude , maybe its the way we are responding to each other as i dont get the impression you want discussion , well not the way you focus on semantics to make a point ...

Case in point your insinuation that i said you would need 500 watts to have good sound, that was never the point of the discussion, as you may or may not like the sound you have , its not my position to say its good or bad, seeing its a personal choice, i was only attempting to give my techical reasoning as to why i would recommend more power if running SS gear on the SF.

If you disagree with my position , I'm fine with that too..

If you would like to discuss, its Ok by me , one subject at a time and without the semantics ...

Regards

Challenges in Faithful Reproduction of Musical Peaks: A Power Amplifier Designer's Perspective Article By Simon Thacher Ph.D. Of Spectron Audio


Check it out , a Good read , touches our discussion a bit , dynamic compression is not readily noticeable to those not suspicious of or not able to recognize it , it's not until one aquires more power , bigger speakers or both , then the bulb goes off ..

Very interesting read...

Thanks.
