Help settle a streaming argument!

based on my personal practice and  observation, the better are your amplifier and speakers, the better they do their job and these differences somehow diminish. 

Or one can interpret your observation a little bit differently. In that, upgrading your speakers AND amps yield much better, impactful, unmistakably audible, results than upgrading your streamer alone. Interpretation which I fully agree. 

Yes. Look at this in this way. Take a 8 cylinder car and a four-cylinder one. When you run fast or go up to a hill you feel that your 8-cilibder car is less forced than the 4 cylinder one. 

Yes indeed. If you can afford a V8 car, and paying for gas for it, go for it! No question better than a four cylinder car. Going from that V4 to the V8 is unquestionnably the most noticable outcome. However, I am sure people with V8s try to squeeze as much as they can from them, thus all the mods, and souped up upgrades. And there is notthing wrong with it too, if you are a car guy (not me).

Boy we must nothing better to do, comparing cars in an audio thread :) Okay, coming off the heels of the last F1 of the year on the weekend, I'll bite :)

In the mid 80's BMW had a 1.5 litre 4 cylinder formula one engine that produced over 1400 hp. More hp than any 12 cylinder engine Ferrari ever had. 

But, but,... there is no turbo on the V12? Different rules!

And it is not about horsepower anyway, it is about torque! and what RPM the motor is at...

and the quality of the fuel being burned

Just going to scaffold on niodari's comment and point out cars are like audio, it is not about a particular specification, it is all about engineering and implementation.

To relate to this thread: car engines are like streamers, usually, the more you spend, the better performance/quality you get. 

(I am agreeing with the previous 5 posts, in case it doesn't look that way :)

You can look at this also in a different way. Consider a car engine as an amplifier and accessories, perhaps tires as a streamer. Most of us, in terms of cars,  have a V6 or V8 or at least V4 turbo amplifiers (which as you know note can have a lot of power). As to cars, I like to drive fast but prefer V4 car with turbo to V6 car, which I also have but do not use it often. V8 feels somehow better but, for me, it is completely unjustified, and anti-ecological, so neither I am a V8 car guy. I associate  a good V4 turbo car with a good class D amp (I have three of them), V6 with a big class AB amp, and V8 with a huge class A amp that is too heavy, consumes too much of energy and gets too hot (a typical Pass Lab amp). I do have one, but it is a 5 watts tube SET,  it is not huge and it consumes not that much of energy (a very compact v8 car which consumes less gas than some V6 cars).
