I have not heard, but have read great things about these monoblocks.

Theta Digital Upgrading Casablanca, Monoblock Amp______________________

By Joseph Palenchar ?? TWICE, 2/1/2012
Montebello, Calif. ? Theta Digital is planning its first Class D amplifier and preparing mulple upgrade opons for its exisng flagship Casablanca III HD preamp/surround processor.
Theta's first Class D amp is the monoblock Prometheus at a suggested $6,000.The card?upgradable Casablanca, whose base price is
a suggested $13,745, will get an oponal $1,995?suggested digital output card that features six pairs of wideband 192kHz AES/EBU outputs for connecon to outboard digital?to?analog convert? ers (DACs) such as Theta's Generaon VIII Series 3. The card ships in February to upgrade previous? ly purchased Casablancas but can also be included in new models ordered from the factory.
A second upgrade is a post?processing card that extends digital audio bandwidth to 192kHz on all channels, adds DTS Neo:X 11.1?channel post?processing, and accepts a bundled daughter card that delivers Dirac Live digital room correcon. The upgrade will make Casablanca the first, or one of the first, audio components to support DTS Neo:X's 11.1?channel capability, said senior sales and markeng VP Jeff Hipps. Select AV receivers currently on the market have a 9.1?channel implemen? taon of Neo:X.
The soluon will be available in June at $3,995 for installaon by dealers and advanced consumers.
Also beginning in June, the post?processing card without Dirac daughter card will be included as a running change in new Casablanca models at no extra charge. Consumers who buy a new Casa? blanca beginning in June and decide later to add Dirac will pay $3,995 for the daughter card, firm? ware upgrade, and calibraon gear.
Dirac Live digital room correcon uses mixed phase processing to improve in?room frequency response and phase errors, reduce first?order reflecons, and improve me?alignment, the company said. Set?up requires a laptop computer and a supplied micro? phone.
Dirac's price includes computer soware, a microphone, USB preamplifier, microphone stand, and all necessary cabling to measure room response and make correcons.
The computer soware would recommend a target response curve based on test tones generated by the Casablanca. Users can edit the recommended curve to suit their personal preferences and store up to four curves in the Casablanca. Each curve could be ed to a parcular Casablanca input, creang music and movie curves and the like.
For its part, DTS Neo:X adds a pair of front?height speakers and a pair of front?wide speakers to a tradional 5.1?channel or 7.1? channel surround?sound speaker system. It up?mixes exisng two?, 5.1? and 7.1?channel soundtracks to up to 11.1 channels. The two front?height channels elevate discrete and ambient sounds, and two front?wide speakers widen the front image and provide smooth tracking of front?to?side acon.
Although the Casablanca previously supported up to 12 channels via Theta's proprietary post?processing technology, that technolo? gy offered up to seven full?band channels and five independent subwoofer channels, Hipps said. The least expensive 12?channel version of Casablanca is $19,370.
Casablanca also decodes Blu?ray's HD Audio codecs and features 3D?capable HDMI inputs and outputs.
In April, the brand will ship the $6,000 Prometheus monoblock amp, which will be the brand's first Class D amplifier.
Unl now, all of Theta's amplifiers were balanced designs with zero global feedback, said Hipps. The new technology drives down distoron. Power is rated at 250 was RMS into 8 ohms, 500 was RMS into 4 ohms and 1,000 was RMS into 2 ohms with less than 0.01 percent THD. The signal?to?noise rao is 128dB A?weighted, and damping factor exceeds 2,500 at any frequency from 0Hz?20 kHz, Hipps said. Unlike typical Class D designs, he added, the frequency response is +0, ?0.5 dB from 20Hz to 20kHz at any impedance load.
Theta is owned by audio?component supplier Amplifier Technology Inc., which also owns the B&K Components, ATI, AudioAccess, and BGW brands.

This is a quote from Theda website, but I will be trying out these amps.
 
Any updates on these amps?

I believe they will be showing at 203 CES as we speak. 750 wpc @4ohms. I just put down a deposit, and looking at 60-90 days for full production.
 
Well reviewed in the latest Stereophile , anybody heard these ?
 
Class D had gone a long way. I would probably prefer the Mola Mola developed by the man himself. Home audition coming my way in a couple of months' time.
 
I've had five Prometheus monoblocks over a year now and luv em! they are easily much better than not only the three Theta enterprise monoblocks I had at center and surround but also noticeably better sonically than the pair of theta citadel 1.5 monoblocks I had at front left and right! So if you are in the Phoenix area contact me and come listen!
 
I have had a pair for some time, and absolutely love them. There was a thread on here somewhere last year that had a few pages of discussion on latest Class D, and I think there were a few posts in there. Very cool that Stereophile reviewed these, glad to see them getting some press!
 
I just discovered them two weeks ago after finally auditioning them in my own system. I plan on adding 5 of them to my system.
