If swithcing amps, at least get more power, more features or at a minimum better looks hehe. Not just a different brand hoping it will sound better.
I am with Dukk, if you "hear" big differences its mostly better power, if you "hear things that warent there before", it's only because you warn't paying enough attention before.
The bigger gains are in speakers and install and more power.

My point is that if he's dropping the big bucks on the Be line, he can afford a better amp than a slash. What does the No. 6 passive run, about $3000?
Do NOT get the Zapco digital amps! You will notice that they simply cannot switch fast enough at higher volumes, and you'll be able to hear it from the top end. Analogue Zapco will last forever too, I'd look at those.

For those that don't know that would be:
Eldridge: MTX and Kicker
Biggs: Kicker and JBL
Cornell: Rockford and Xtant
Pitt: Rockford
Where's that high end euro stuff?
And as for only few in the world can tell good sound quality from an amp. Doesnt take a superhuman its called a mic and a test cd found at your local iasca comp... test and 1 2 3 anyone can notice the difference. But i guess since nothing else was noted, you must be one of those true listeners to notice that audible difference.

Methodman0666 can describe it better than I can, as he currently has these in his Caddy. The short version is that the transistors can't switch fast enough and therefore not enough current can get through. The result is a slightly noisier and muffled top end.

^ That's right. The reason you don't see many full range Class D (or similar) amps is that the power supply has to switch at XX (yeah so I forget exactly) times the frequency being played to keep it noise free and it's a lot tougher to do that for a 20,000hz note than a 200hz note.

I always thought they are A/B?
not trying to nitpick, just figuring it out.

Digital does not mean Class D. Class D is simply a switching amplifier (pure on/off circuit, as opposed to an AB class, which keeps partially open channels). The Zapco amps just happen to have digital processing on board for the DC line, and are often referred to as a "digital" amp.
Conveniently, the Zapco site and manuals do not list the class of the DC Reference line of amps, but judging by some of the specs and having heard a few, Class D is not out of the question. You can definitely hear the top end struggling. Bass is loud and clear.
