the only reason it will sound cleaner by swapping amps, is because you actually are getting more power out of the new amp. precision power typically centers it's focus on eliminating any noise, and acheiving a very linear response. unless you're only in the lanes with your car, or you have money to burn, there's alot more bang for the buck out there....

there is still an outstanding $10,000 prize available for anybody that can audibly tell the difference between two amplifiers that are putting out the exact same power.

and yes, I've been installing for a little over 4 years.
