It is not a fully balanced differential amp. It is class D using the N-Core NC-1200 modules we use in Prometheus. With even a small amount of good luck, we will be shipping the initial orders next week.

The Dreadnaught D link is on the Theta website, but it's a broken link. I'm sure it will be fixed soon...

I don't think I've got much pre-1900, but I've got a large collection from 1900-1935 of early pop, blues and jazz, country, etc. The rest is the more mainstream pop from 1940s onwards until most 78s ended in the late 1950s. Many known artists and many unknown. It's been fun collecting and spinning them. This year I've got to catalogue it and deep clean them. Because of the quantity and my lack of time, they haven't been given the dignity they deserve. It's on my to-do list. It's my own little collection of preserving music history. Most of these would be destined for the garbage bin, which is a shame. The young generation now would never attempt to download Walter Van Brunt's 1910 recording of the then-popular song Any Little Girl, That's a Nice Little Girl, Is the Right Little Girl For Me, written by Fred Fisher. The music may be in the archives in the library where they've got several hundred thousand 78s sitting somewhere, but I feel my music collection is enriched with this early, innocent music, that I'd never be able to get anywhere ever other than the old folk who are dumping their 78s. It also looks like 78s is a great archival format. I doubt CD players will be around in 20 years making all CDs coasters for antique shops. I think people will still be spinning records 20 years from now.


What a contrast my playback system is - leading digital components driving music from discs over 110 years old. Crazy!

Yep, the link works, but the gallery is having issues. When clicking on one of the pictures, a window opens, but it just hangs there for me.

Actually it's only "nearly" fixed. Specs, operator's manual and rear-panel renderings are good. Most of the front-page copy is yet to be written and the slide-show is not working. If you need pix, drop me a line: jeff at ati-amp dot com

Hey cannga


1) From an older post, yes, it was I who inspired your "Casablanca Kisses". I may need to make my own now!


2) My vinyl 33.3/45rpm collection is small. No more than 100 good ones, bought new. Maybe 100 old ones passed down to me on top of that. The 78rpm shellac disc is a recent interest revived. A few years back I started collecting a few on the local used online ads because I was interested in hearing how they sounded. There was something very nostalgic about it, more so than the 33s. I didn't know much about it, so I probably paid too much for many of my initial ones. After a few runs to different houses, I stopped after I got my fill. Fast forward a few years and it wasn't until recently until I became acquainted with an older gentleman, a used record seller, who comes across 78s all of the time. When he gets them, he calls me.


As I mentioned in a previous post, I have no interest in reselling these and I don't care about what people are trying to put as value on them. To me it's completely unimportant. I find it hilarious that people are eBaying each disc for $10. Whatever! Those are the people that sit on their junk forever and never get rid of it because they are asking too high. Who are they trying to sell to anyways? Sellers who won't pay that price? The one collecting person who may be looking for that disc as an art project? That market is super small. My frame of mind is to build a library of them for historical listening purposes only. Not relevant to most people, but relevant to me as I browse my music collection. I can pull a song from the new catalogue or go deep into the archives... Most importantly, I really enjoy the music from those eras and I'm not happy with most that's out today. It seems that I'm interested in amassing content from 1880s-1940s or so, and then anything else is after that is just my preference. I only have so much room I'm not even starting on 33rpm vinyl. If I want a song from that era, I can get a high rez download or off the CD for cleaner playback, providing its dynamics aren't squished beyond enjoyment. I will never have that option with the older stuff which is why I've just gone right to the shellac discs that people are dumping on a daily basis.

How many channels share a signal power supply?

Two transformers. Each has 4 independent secondary windings and outputs.

Ok so 8 independent power rails for the main unregulated supplies? Do the signal stage and driver voltages share a supply? If they are all independent, that's quite feat squeezing all that in the box.

I'm curious about this as well. Hopefully, Jeff or Craig will respond, although, I left a voice mail for Craig last week and have not heard back from him. Vacation maybe, or just super busy I can imagine?

Doesn't appear to be happening until at least 4th quarter, or even later.

Xtreme D3 DAC's will be used in the Theta Digital room at the Newport Audio show beginning next week. We're in room 1310 driving Wilson Audio Sabrina's with a CB IV and a pair of Prometheus amps. We will also have a Dread D on-hand but do not currently expect to be using it for sound.

Hi Jeff,

Sounds good, but when will those D3 DAC's be available for sale?

Leave Craig alone. He's in Florida on vacation!!!

As for the new Casablanca DACs, patience, patience. When I talked with several folks at Theta a few weeks ago, they could give no date yet, apparently still being worked on and/or supplier issue? As with the Dreadnaught D, when they get very very close, either Jeff or Craig/VGI will tell us, that's for sure!

I wonder what one does in Florida on vacation, other than Disneyworld or Universal Studios, or visiting Sim2 to see their projectors? See below for Florida activities:
