[QUOTE="Wingman0121, post: 7089549, member: 620554"] I had a Crossfire CFA1000D when it first came out, they were the first 1000 watt class D amps ever made so I was on the wagon from day 1. I never liked how it sounds when compared to my home subwoofer at the time but I was able to pull a 148.8dB in a VW Golf on an AC mic with it. I switched to an US Amps USA-2000X for a short time and it was literally night and day difference with the same TS-W2000SPL subs in the same box and car. Of course it was louder(it is a bigger amp) but the bass sounds completely different - the bass was much tighter and deeper with the 2000X than the Crossfire. It isn't fair to compare the Crossfire to the US Amps but there are definitely audible differences between the two, a good example is how tube amps sounds different from a solid-state amp and the sound characteristics will change if you use a different set of tubes. Of course people argue that vacuum tube adds nothing but distortion but if that's true then there wouldn't be a community of high-end tube amps that cost thousands or a lot more. I've owned several home theater amps and some do have their own "sound" no matter if the volume is at 1/4 or 3/4. [/QUOTE]
