Average Reviews:
(More customer reviews)After paying this much for an amp, my expectations were quite high.
The amp exceeded every expectation I had.
First- The build quality is absolutely top rate. The removable connectors fit very tightly. The removable control panel has a positive lock so it can not vibrate or make noise. The RCA inputs are of excellent quality. A nice touch is that you can mount the amp on either side. This was nice because in my installation it worked better to have the back side facing up.
The next thing I observed after the installation was how low the noise floor really was. I could not hear it. The noise I could barely hear was actually coming from the source deck. I measured the noise floor at -109 Db with an Audio Precision Portable 1. That is the best I have ever measured on a car audio device. The ground isolated RCA inputs are a nice touch. No ground loops are possible.
In my installation I am using it to power a set of JBL 660GTi speakers in bi-amp mode.
I was worried that the anti-clipping circuitry or being a full digital amp would color the sound. I had nothing to worry about. The sound is very smooth and the transients are sharp and clear, but not harsh. When driven hard, I could detect the anti-clipping circuitry activating, but it was not too objectionable.
I was surprised that the amp is quite efficient. The fuse size is only 50A, for a 600 watt RMS amp.
I am very satisfied with this purchase.
