Their CES-announced "mighty" Prometheus "powerhouse" uses a "European-sourced module", later called "Phiips Hypex".   

200 watts @ 8 ohms with Theta's own power supply.   $12,000 a pair.

NCores?   modded UcD?   Anyone know more?

I would think at that cost it's the NC1200 module.

If you go to Theta's website, you will see that Theta is no longer promoting the Prometheus amps.

Theta has a current Facebook page, so they still must be alive.

This is from Stereophile 2013 CES show report. Theta is to release their Prometheus Class D Hypex amps in the next 60-90 days.

These are the coolest looking of the production models.

200w/channel would not be the nc1200.

NC200?  200 watts into 8 ohms?  And they are not using the SMPS.   Seems weird to me.  Oh yeah, and $12,000!

Well, 200W into 8 ohms is right for the NC400, but that is not likely since it's pretty much off-limits to VARs. For that money, I can't believe it's any UcD module (also the timing is odd for that), so I'd bet it's the NC1200 and somebody just got the power spec wrong (should be 350W into 8 ohms).

   Me as well. Theta did not honor their lifetime upgrade path as advertised. Spent $5500 on DAC and now cannot use it. They lost my trust. The Amp is pretty though.

It is my understanding that Hypex has released an upgraded UcD module for OEMs, that has some NCore trickle down technology, perhaps this is the module Theta is using(?)

[Regnad]

It makes me think that the NC1200 module is quite expensive for the OEMs.  Anyone know how much? 

Why would Theta use their own power supply when the SMPS that is used is only $200 or so?  Surely their power supply would be more expensive, why not go with the matching one?  There are efficiency, size and heat considerations as well.

Theta is still going to release the amps. Could it be that the linear power supply they are using is limiting the output?  Theta specs the amps at 250 watts RMS into 8 ohms, 500 watts RMS into 4 ohms and 1,000 watts into 2 ohms. Often companies understate the 8ohm output for marketing purposes to make the amp look like it doubles as the impendance is halfed. The descreprancy could also be a result of how power ratiing are interperted. Rating for power into 2ohm at 1% distorting for example could be higher than if the company used for example .005 distortion as a target. Mcintosh amps when reviewed typically show higher output than what Mcintosh states because they measure at .005 I believe and the reviews often measure at 1%.

Contact Approved Audio Service and see what they say. Theta may not be doing repairs for the older gear since they were purchased by ATI. I believe ATI implemented that policy. Approved Audio Service likely can either offer assistance or do the repair. They handle gear from stuff either out of business or no longer supported and do very good work.
