The best: Whether a mpli 4 channels, a power sufficient largemeent (4 * 200 Watts into 8 Ohms)
The least: It weighs! a good twenty pounds anyway ...
How would you rate the quality / price?
I do not know ... I made the choice to buy a 4 channel amp rather than two 2-channel amp to power my 4 encintes. I did not informed about the prices of two-way amplifiers. But yes, I think I will ever be the choice
