Are quantum amps any good?

How good quaity are db drive amps?

• im looking at getting a new amp. mine decided to burn out on me. i need at least 2000 watts rms, probably more like 4000 rms but 2000+ will do. i need a good quality amp, like clean power. im looking at the db drive amps. okur series. they seem reasonable. i actually have in mind a a4 1800 or a4 2400. are these amps good clean power? any info from someone who actually knows what their talking about would help. thanks, greg.

• Answer:

  i say there in the top 10 best brands for amplifiers. manly used for competitions. there price ranges are about right for what they do and compared to other amplifier brands there reasonable. check out crescendo audio Bc3500/3850 1ohm shipped $600 and comes with clipping indicators so you know when your amp is clipping. i dont think db drive does. also atomic amplifiers are another top of the line brand that wont burn your wallet either. also you wont want a class AB amplifier which are the A3's and A4's. which are not as efficient as class D amplifiers go with the A7's class D best ones they make. CLASS D These use switching to achieve a very high power efficiency (more than 90% in modern designs). By allowing each output device to be either fully on or off, losses are minimized. The analog output is created by pulse-width modulation; i.e., the active element is switched on for shorter or longer intervals instead of modifying its resistance. There are more complicated switching schemes like sigma-delta modulation, to improve some performance aspects like lower distortions or better efficiency. Class AB Here the two active elements conduct more than half of the time as a means to reduce the cross-over distortions of class-B amplifiers. In the example of the complementary emitter followers a bias network allows for more or less quiescent current thus providing an operating point somewhere between class A and class B. Sometimes a figure is added (e.g., AB1 or AB2) for vacuum-tube stages where the grid voltage is always negative with respect to the cathode (class AB1) or may be slightly positive (hence drawing grid current, adding more distortion, but giving slightly higher output power) on signal peaks (class AB2). Solid-state class-AB amplifier circuits are one of the most popular amplifier topologies used today. so ab might add more power at peak times but will use more battery power and distortion is higher as well
