Big difference in quality??

I've always been a firm believer in you get what you pay for. I know Alpine and I know they have great amps (or, at least, they used to). I've had Alpine amps in the past and they have performed flawlessly for years. I've never own a Massive Audio amp, but there is a huge price difference...too much for me. It's almost like the price of a Boss Audio or Planet Audio, or something similar that I would not touch. I would look at it this way: If you buy the cheaper product, you will enjoy the cost savings for a week or two. After that, you will forget about your savings. If you buy the better, more expensive product, you will enjoy it's benefits for years to come, long after you've recovered from paying the extra dollars. For me, I'd get the Alpine.

The alpine is a superior amp and will get you 100 clean watts per channel but that's why it's 500 vs the 130 tag on an nx4. If you only need 75 watts per channel the nx4 will likely get the job done. If you need 100 watts per channel perhaps explore some budget 4 channels that have been tested. Maybe like a ppi i520.4 or even something like a 900.4 or tn4.900 and keep your gains down.

There was a massive difference between the "tested" ppi 900.4 against an alpine PDX-F6 from my direct swap test. Detail, clarity, overall output was massive. Felt like going from a boss amp to a korean amp.

Both are good quality.

What's the question really...?

It's kinda like comparing a granny smith apple to another.

Of course but price is 450$ vs 150$. Btw Amazon warehouse has that pdx f6 for 309 used right now. Pretty solid happy medium in performance to price.

Here's the real question: What can the 450 dollar amp do that the 150 dollar amp cannot do?

Well the 450 dollar amp has a regulated power supply. That may or may not matter.

I completely beg to differ. The amp with more clean undistorted power will always win. The lower quality amp will sound like @ss past .01 THD, even though it claims more power, its not gonna be squeeky clean power hence the percieved sound quality difference everyone claims they hear from swapping amps. Higher quality amps sound better because they make actual clean power which just means they make music sound as it should, not coloured by distortion

Important note, distortion and clipping is not the same thing. You can have a lot of distortion even before the sine waves clip.

Clean power, better results. Pdx f6 is supposed to be only 5 watts more than my ppi amp which has been amp dyno'd to do rated but the drop in test result difference is absolutely devasting for the ppi. Regulated power supplies make a huge difference. You can hate on expensive mainstream sh*t all you want, but they are clearly superior in both build quality, technology and performance which makes them unaffordable to guys like us who mainly seek out the best deals and get mislead by others saying that a cheap manufacturered amp with a recycled generic design made in china is somehow as good as a the other company's flagship amp line that has years of R and D and patents on their technology.

I just want matching amps so I'm thinking about swapping either my PDX for a nx4 or my n3 for a pdx1000

Buy the nx4 keep the alpine swap and listen. If you dont notice a difference sell the alpine. If you notice a big difference sell the nx4 and n3 and buy a pdx1000
