Congrats on buying the RD's, but once again(as others have also attempted) let me reitterate.
The RD Amplifiers DOES NOT use the same components in the creation of the amplifier! Please quit misinforming people that it is the exact same amplifier. It is not. The RD will hold .5 daily, 18v inputs and more than likely, honestly, has better cooling. I'm sure there's other subtle changes and whatnot, not to mention better quality parts that help these few differences.
I do have to agree that it's nice to be able to talk to the owner of the company instead of a rep though, that's a huge plus!
Well I guess it time for me to chime in and end this little debate.
Audiopipe is ran/owned by a man named Gonzi. On the 09' new line many new improvements were being made. The older 2000d (gd6001) amps were made in Korea and where high in cost. The AP30001 amps were made in China at a lower cost to make best amp for the best price. They have been selling like crazy this past year. Now I know for a fact that I wanted to see AP sell a strappable amp that could do 7k per pair.
Now, I have no clue about the RD testing or design of their new amp! I have a question about it. Did they do their testing of the new amps at RD?
Well I know that Gonzi didn't test their new amps at the Audiopipe warehouse. He, in fact, flew half way around the world to China, himself, straight to the factory that makes these items.
I know they had several versions of the amp, before they found the one that would do what guys like me wanted from an amp used in comps. A pair of strapped amps that would not go into protect if the ohm load was a little low and would handle 16/18 volt setups and not blow up after 10 or 20 runs. Gonzi stayed in China for 3 weeks to oversee all progess and to have some awesome new products for their 09' line up. I know that me and Gonzi exchanged at least 40 plus emails while he was there at the factory.
Now for you guys that always want some kind of proof, either test the two amps at the same time or just buy from which company you want the name on the amp.
Both of these amps are really great for the prices!
It's your choice to go RD or AP !!
I know, if the doctors haven't found my cancer earlier this year, my van would be full of these new AQX-3500.1 amps.
He is a little proof of Gonzi in test mode at the China factory last winter.
