Can DLS Ultimate amps compete with Arc's XXK line ?

Why would the first sub catch all the heat if you wire them in parallel?
Perhaps I'm wrong there, but one is using the first subs terminals a distro to feed another.

Who in their right mind doesn't seal off one woofer from another?

Cool

I'm just stating the obvious differences, as to why I'd pick one over the other. Doesn't mean you have to based on my preferences. Diff strokes for dif folks -particularly at these price points. Two diff products.

DLS does make an awesome amp, a look at the board layouts indicates crazy power supply design.

Some say DLS amps are made by the build house of Genesis (although not comfirmed) I have heard they run extremely hot from some heads at ECA, apparently as they are not very large in size considering the power output, but they have a very nice chassis/heatsinks. Nothing wrong with an amp running hot anyhow (thats what the byproduct of making power is) .

I just dont need my power at 1ohm, so i look elsewhere. If I'm paying for supossed 'clean output', i want all that power and dampning as clean as possible- i mean why else pay more? If I want a 1ohm stable amp to give me 1-10% thd making full power, i might as well buy a hifonics.

I just want to make someting known, in a closed circuit such as your subs, the voltage throughout the system is the same, unless there is a voltage drop in the wiring. The first sub will see the same wattage as the second, when wired in parallel. Parallel wiring is how the lower impedences are achieved. Ideally, your amp would make the highest power at 4ohms to better utilize it's damping factor. It's my understanding that as circuit impedence( resistance/ohms) decreases, sound quality decreases as well. I don't think it matters as much for subs as mids and highs. I just wanted to say that according to ohm's law in a parallel circuit all the branches will have the same voltage/wattage.

Wow it has a greater than 2000 damping factor but is not 1 ohm stable? Is the damping fator tested at 4 ohms & 1 Khz?
I see it's rated at 1 khz so what is the damping going to be runnign woofers?

I believe there are different ways to measure the damping factor is all, so it does no necessarly kill the DLS. But for wanting subs in sterio it looks like the ARC is hte best way to go.

What is the purpose in running the subs in sterio again?

Having done some serious considering , my bud went with the Arc amps. His reasons were substantial enough to list here in my opinion.

#1 - The Arc makes the same power in 4 ohm bridged , as the DLS does in 1 ohm mono ...... This makes the Arc a waaay more powerful amp , and allows it to keep a higher damping factor ( 4 ohms compared to 1 ohm ) , and make it's power with less heat generated. Should also have lower distortion at 4 ohms compared to 1 ohm .... It also allows the choice of using stereo , with the benefit of individual gains per sub ......

I'm quite sure the DLS is very nice , but the Arc just seems better for subs.

Thanks for everyone's input !
