The sweetest deal in digital amps just got sweeter.  We are running a special on the finished Exodus Amplifiers.    This applies only to non-kit sales and these prices are only good for AudioCircle members.     

Free UPS GND anywhere in the lower 48 states!   

Free 6ft Asylum Cable!

50% Discount on assembly labor for all EX-400 amplifier models!

This translates into big savings for those looking for the newest state-of the art digital amplification.   

Example Amplifier Prices:

$1045 Shipped!   Save $240 on the EX-400ST-2  two-channel Amplifier with 400W into 4 ohms of pure digital power!   

$1725 Shipped!   Save almost $400 on the  EX-400ST-5   Five Channel Amplifier with 400W into 4 ohms of power into all five channels!   

In return for these excellent values we ask only one thing from the customers who take advantage of these offers.   We ask that each customer review their amplifier both on AudioCircle and we ask for a short synopsis of the review to be entered under our review section on the DIYCable web site.    I'm not going to twist any arms to write the review.   It will be based upon the honor system. 

Our main goal is to get more exposure for these excellent amplifiers and I'm trying to foster more awareness of the product.    This special is for a limited time only and we reserve the right to end this special as our supply dwindles.    Don't sit on the fence if your interested.

Excellent marketing idea Kevin. 

I am looking at these as a replacement in the future (just not ready financially yet).  However, I have been leaning more towards DIY lately, both for economic reasons and the education/enjoyment of the process.

I hope some will jump on this as I look forward to peoples reviews on these amps.

Thanks,
Mike

Thanks Mike... hope it works.   

I've got a couple reviews lined up but those are months away from being published.   I've always liked consumer reviews from people who actually own the product anyway.   You have to read between the lines sometimes but you almost always get honest feedback from people who actually spend their own money.

Hi Kevin,
I will be in your neck of the woods on the 8 and 9th of December.  I have a grandmother-in-law up there.  Maybe I will check your stuff out.

Hi, Kevin!  Sweet deal.

I might pull the trigger on this great deal to run the subwoofer array on my Definition Pros.  This consists of 4 - 10" drivers per side operating from 100 hz down to about 15 hz.  The drivers need a tremendous amount of amplifier control to keep them "tight".  But, they are fairly efficient and don't actually need a ton of power. 

I had a Bel Canto e.one 300 (ICEpower) at 100 wpc that didn't work too well.  I've also tried an Adcom 555II and a NAD 912 with lackluster results.  Currently, I'm using the power section of a 65 wpc Audiolab integrated which surprisingly is doing pretty well, though it's not nearly as articulate as I know is possible.

Do you think this amp would work well in this application?  It needs to be agile at low volumes but with tons of damping.  If it doesn't work too well, is there a trial period?

Thanks much,

Mike

Aside from having loads of headroom, is there a problem powering a speaker with more watts than recommended by the speaker manufacturer? Obviously you could turn it up too loud and blow the drivers d/t overexcursion. Beyond that, is there a detriment? I'm just asking because the cost increase of going from 180 watts to 400 watts is very small considering the fact that you are more than doubling the power. If it doesn't really cause that many problems, then it makes sense to get the bigger amp to allow more options with speaker selection in the future.

It doesn't really matter.   Loudspeaker ratings are sort of a joke anyway.   Power ratings are theoretically determined by the amount of heat the VC/former can dissipate and withstand.   The thermal mass of the VC, former, ambient temp and the amount of air movement over those parts are what determines how much power can be dissipated.   In most failures the problem is with physical parts breaking rather than smoking a VC but it depends on the design of the entire system.

To make a long story short the extra power isn't going to damage loudspeakers unless you intentionally turn it up and do so through an act of stupidity.    The short little micro-burst of dynamics actually favors the higher power modules and it makes a lot of sense to me to buy the UcD400 based units even if you don't need the power.    The difference in cost is not that great and the UcD400 builds gives you more flexibility.

I have a lot of people asking to come in but I don't have a retail store front.   Just a warehouse, assembly shop, and an area to take measurements.

Since all of my amplifier builds are custom (we don't have a standard configuration) we don't really have a trial period.   I've been meaning to make up a demo amp but I keep selling them as they get made.        The damping factor of all these amps is dominated by the impedance of the cables you have hooked up to them.    How it would subjectively sound is somewhat of a guess in a given system.   I could tell you some BS but the truth of the matter is that the amp shouldn't be the deciding factor in how articulate your bass is.   The room/subwoofer interface along with the acoustic design of the system should be the primary determinate of perceived sound quality and if you are hearing large differences between amplifiers under 100Hz I'd be suspicious of something else.    With extreme examples of amps with low damping (SET amplifiers) you actually get a higher final Q which may actually give a perceived INCREASE in bass output & articulation.   You can accomplish the same thing though by designing the given Q into the acoustical side of the equation (box/drivers).     Maybe your cheaper amp actually has poor damping characteristics and your perceiving that as a good thing?
