I think we are looking at the same graph. In some of mine, they are in color, in others it is multi-color.
So.....assuming that we are......look closely at the area between 10 kHz and 20 kHz. You will some slight variations.
At first, you may not think that little change is audible. I can assure you that is. Very audible. Which is why you need to listen to one on the system you intend to purchase one for.
Look......all amps will interact to some extent with the speaker. These amps just happen to have a particular type of interaction that will be much more audible to the average listener.
At some other time, I can relate a story about RIAA networks, and how very noticable a difference of 0.25 dB is. If not, let me say that most RIAA networks have a hump of around that much from 250-500 Hz. Very hard to take out. Very few products take it out. (Some leave it in on purpose..........)
You can verify this by listening to CDs and LPs that you have in both formats. Some will prefer the warmer sound of vinyl, and others the "accuracy" of CD. Not the point which is better. Just to demonstrate how little of a frequency change can make very large changes in perceived sonics.
Anyone wanting info on stuff that I make, or have made, is welcome to send me an e-mail or PM. I would rather discuss items of technical nature that interest me, than bang the drum for our products. OK?
(There is more than one thread that deals with not being able to identify myself and my company without screaming "www.buy.my.amps.com".)
