Who knows how much the dampening of the cases and cones used on each case might impact the sound???
Don't misunderstand my comments. Stereophile is my favorite publication. I have always saved my new issues for vacation travel. Pack clothes and get the latest copy of Stereophile for the plane ride! Always a way to start a great vacation!
The story with Hypex and Hypex Done right as far as Theta sees it is that it doesn't work nearly as well with a Switching Supply. When you front end it with a Huge Linear like theta has done on the Prometheus and the Dreadnaught 4 the game changes.
Dave Reich for years tried to get the NCore 1200 to sound awesome and couldn't do it.. He wanted to use a Switching supply because the weight would have been great but after years of working with this module he finally struck gold when he coupled it with his Linear Design.. There was no reason for Dave to do this like he did except for Sonics.. They found that when pumped with Linear the NC1200 comes alive.. I knew it the minute I heard the Prometheus and now people that have them are all saying the same thing.. Stereophile of course helps by writing such nice things but we all knew months back that the Prometheus were great.. On Aerials/Josephs and quite a few others we are stunned and dumbfounded how good the amps sound..
The Dreadnaught 4 should accomplish almost the same thing and in some respects can do more. Considering the Dread 4 can be ordered with up to 4 modules that can be Bridged to 2XNC1200's delivering 400WPS@8 X 4 Modules.
Yesterday a customer configured a really nice Dread 4 like this -
3 Bridged Stereo Modules 400WPC X 3
1 Stereo Module 225X2
A super charged 5 channel amp.
Does anyone need to bridge a Hypex Module and have 400WPC into one channel, I don't know.. I used to think so but if you ask Steve Bruzonsky how his Prometheus performs with 250 WPC VS his Prior Citadel at 425 WPC.. He will take the Prometheus all day long..
Prometheus feels like 500WPC from anything I have ever heard in the past and I don't really know why but it does.
The Theta Ncore solution they have produced with the Dread 4 and Prometheus is going to change the amplifier industry forever. My opinion of course
