i started out with pn4 1000d amp and kappas, it was loud, damn loud.
but it lacked alot of the musical undertones, clarity, depth of good instrumentals and vocals.
i upgraded to pro audio speakers and horns with same amp, the clarity that i was after was closer, but lacked the full depth of some vocals and instrumentals.
next time around i upgraded pro audio mids again and went with JL XD amp, and i will say im about as close as ive ever been.
how much of that sound change do you attribute to amp and how much to speaker change?

I’ve heard that before. I’m assuming it has to do with the type of filters and chip set each amp brand uses.

I posted this question because I have heard it many times in different conversations but have never known the exact explanation. So far most of the replies have been in the general area or idea that I thought it is. There are so many things/terms that are used and they may or may not have a definite definition as to what the real meaning is.

I'm my mind it is how the amp is designed and the parts (filters/capacitors ....) that are used to create the signal and are the things that decide warmth or not. I may be totally wrong but I was/ am under the impression that a warm amp tends to produce lower or softer sound, when a not so warm amp produces the crisp or even harsh sound.

Any way thanks for you replies it's interesting to here every ones explanations.

Brad

Does adding a dsp to an amp that is NOT warm, bring back the warmth?

Given what has just been mentioned, are there any amps that offer the power that the PN4.1000d in a similar size that sound "warm"?

I haven't seen many that will do what I am asking of this little amp (drive six speakers well) that fit under the hood.

JL xd400 or xd600/6 or maybe twin mx500 would be the closest I could think of. If you could make a amp with the sound of a JL and the power of a bt4250 you would be a hero.

So if someone were running the JL xd400 for the four front speakers would they use 2 ohm speakers to eek out the 100W per channel rating of that amp or do they usually stick with 4 ohm speakers and go with the 75W per channel for optimum clarity?

I have come to the conclusion that these amps (bt4250, focal sport) are over powering the speakers causing a ton of distortion on the low end and very piercing highs on the top. These amp have a ton of power and we are throwing it at speakers 2x the power they were intended and built for. The highs can be reduced by backing off the gain but the distortion on the low end can only be stopped by increasing the hp filter. When you do that, there is only the highs and no chance of any lows do to the over power. Hence I am now running the tm400x4ad and no filters in place instead of the focal I had. I now can have all the low end any 6.5 can give. The miiles 6x9 also rock the back end. Yea I loose some db's in the volume but gladly give that up for a fuller, not so damn crisp tinny sound. As I have said, not all watts are created equal and I can still hear it at 70. Some food for thought.
