The reasons have been posted several times, but you're too stupid or stubborn to notice.
(1.) Zenon amplifiers can safely handle ohm loads that would destroy lesser equipment.
(2.) Many companies that sell these amplifiers offer transferable warranties.
(3.) Zenon amplifiers have great resale value.
(4.) The amps are affordable considering their build quality, reliability and reputation.
(5.) Zenon amplifiers produce more than rated, cleanly.
And yes, customer service is very important. If you drop $500+ on an amplifier that arrives DOA or has issues, you'll want a replacement with minimal hassle.
The zenon amps are built like tanks and their reputation is well deserved. But I'm not calling the Discus or Ground Pounder series' junk, stupid. If you care to take a look, I'm constantly recommending the dsc amps to people on a budget. Pretty much on a daily basis. But the fact remains; If you can afford the extra cash, Zenon is a better option. Simple as that. Once you get a little more experience you'll learn things like this.
And for the record, I call you names because you constantly spew stupidity. Stop saying stupid shit in every single post and I'll show you some respect. A prime example of the stupidity is your statement about chasing numbers and not wanting to damage your hearing. Why run a 3,000 watt subwoofer if you don't care about getting loud? Why say "Cadence is the best because they hold such & such records in db drag" and then turn around and preach about retaining your hearing. It's fucking ignorance, man. Educate yourself on topics before chiming in with redundant, meaningless bullshit over & over...
