Well this is weird. Last night, the amp worked fine. I turned it on and off multiple times and it worked as if nothing ever happened.

Any news on Dirac Live?
post #4986 of 6787
When there is news I will hear it and you know me, my web "pen" is my sword.
When there is no news you will see nothing posted here.
HA!

Yes, it can improve MC systems. I think you get a more seamless sound field with the newer room correction technologies. Most surrounds are very near to the wall. Most wall surfaces are hard and reflective. Even if you are avoiding bass issues by routing to a sub, the reflectivity of the wall can still make the surrounds have a different timbre from the fronts even when the surround have been designed to match the fronts in timbre. If you have your surrounds on stands, away from the wall, the effect is less but you still have the effect of them not being at the same height unless the stands are designed to allow proper placement.. Steve Bruzonsky uses identical floor standers placed away from the walls. This approach reduces some of the boundary effects, I notice from surrounds being placed on walls.

Marketing matters. Dirac understands this which is why I believe they are moving to 24/92 capability. They could take the "high road' and lose sales or "swim with the current." This is not directed at you or anyone on this thread. My past experience with companies makes it difficult to tell when they truly believe something or when they are just "spinning" me because it's not profitable or feasible to implement technology.

Listening to come Cowboy Junkies, SACD rip converted to 24/176 via Jriver into the Gen VIIIs3. Wow, I feel like my mind is being messaged smile.gif . Summer's coming. I'm going to have to bring this to the beach with me. I'm still in love with the Gen VIII, such power and dynamics. It's like she's, lead singer of the Junkies, whispering in my ear. Oh, is this this mental infidelity? It must be smile.gif. "Baby Please Don't Go," through the Gen VIII is so clear and intimate, it reminds me of a live performance up close at Tipatina's when they played there in 2010. There's some real, "life, magic" in the Gen VIII that I seldom hear in audio equipment. I am biased as I do and have attended hundreds of live music events in New Orleans. If you come to New Orleans, Bourbon Street is not the place to go for real music. Go to Tips http://www.tipitinas.com/

I've listened to the Cowboy Junkies, and I'm here in the sun drinking a beer but with only a pool, no ocean - even when I'm in my audio-theater room! With my Theta Gen VIII, Citadel 1.5s, Aerial9s, Bryston BDP-1 Media Player, playing 176-24 PCM! Better yet even Shelby Linn's 2008 tour de force of Dusty Springfield hits from the 60s. The Gen VIII Series 3 is remarkable! James Taylor's 192-24 "Fire and Rain" and assorted early hits from his first "solo" album are - gee, I am listening to him playing live!@@@

Lon ,

They are working so hard on the new PR3 card you wouldn't believe.

Making good strides and and trust me its going to be awesome.

Keep in mind the new board is also going to have all new Digi In's handling 24/192 across all digi inputs.

Still work to do so if i were to guess , i would say end of summer but its complicated and they dont want to rush it..

Its going to be awesome !!

Thanks Craig!!

Any Blanca owners with directv can you tune to premium channels (hbo, Cinemax..) and let me know if these channels lock up your Blanca? I haven't watched these channels in a few weeks but they cause my Blanca to lock up and lose sound. Regular stations are ok. A soft reboot of directv receiver unlocks sound until I tune to premiums and then lockup. This affects all my receivers feeding Blanca

Never

Never heard of this one.. Sounds bizarre.. Nothing else causes this ? No other sources ?

Are they HR24's ? Is the Digital out set to Dolby in settings ?
post #4994 of 6787
Yeah its a very odd, I tried changing the receivers from dolby digital on to dolby digital off and no help. UGH. No other sources so far just directv premium channels

Will any of the HD Dacs work with the PR3 card, or only select Dacs? Going to have to break down and get a CB3 soon smile.gif

Tracked issue down to latest Lumagen Radiance upgrade, went back to previous software revision all is good

Guys,

curious if the Premium Dac is a newer design than the Superior II dac - was looking here: http://www.thetadigital.com/casablanca_iiihd_controller_specifications.shtml#dac_cards and seems like the Prem is a better option, @ 4 channels compared to the Superior II at 3-channels..., in addition to these noted differences:

Superior II:
DA - 24-bit Ladder (8X oversampling - 4x oversampling for 96KHz sources). Two DACs per channel (6 per board) for true differential operation.

Compared To:

Premium:
DA - 24-bit Ladder (8x oversampling - 4x @96K). Two DACs per channel (8 per board) for true differential operation.


Superior II:
Digi Filter - Theta proprietary FIR filter running on Motorola 56362 DSP. (isn't this an old chip?)

Compared To

Premium:
Digi Filter - 8x digital interpolation followed by 64x delta-sigma modulator.


Superior II:
Output Imp 10 ohms & Max output level 10vrms

Compared To:


Premium:
Output Imp 50 ohms & Max output level 20 vrms balanced (this is the comparison I know least about, so curious if these #'s are significant in the comparison) - PLEASE HELP smile.gif


Everything else with the exception of the sample rate supported appears to be the same. I'm noodling on the a-gon black unit Craig has available, and just trying to determine if getting the premium card makes more sense as the unit has Premiumx2.

My understanding is that the upcoming new DSP board, and the new Dirac Live board, will work with the Extreme DACs and Premium DACs, but not the Superior II DACs, so I think any interest you may have had in the Superior II DACs is now relegated to the junkyard!!!@@@

Not a problem. But I too have the Radiance XE, and occasionally, if I use the Radiance to pass audio into the CB3 HD, the Radiance may lock up - needing to unplug power for 20 seconds and then replug and turn Radiance back on and all is fine.

You are incorrect !!!

The Xtreme, Premium and Superior II dacs will be supported under the Dirac and PR3 Upgrade !

Thanks

This is what happens after one turns 60. One loses it!!@@@

By the way, I have confirmed, using JRiver Media Center with my Toshiba laptop (which has a full size HDMI output), that the CB3 HD via HDMI shows the audio resolution up to and including 192-24!!@@@

I'm thinking of adding a Theta GenVIII series 3 to my system that is powered by the Datasat RS20i.

I see it has unity gain available on all inputs. But if I connect it digitally to my RS20i I will be subject to downsampling of HDMI inputs as per hdmi (hdcp) licensing dictates. How does the Casablanca get round this issue when you use a gen vIII as you main dacs?

It does not get around it, same downsampling of HDMI sources takes place. Only way around this is a proprietary encrypted digital link, which the CBIII to GenVIII does not have.

Just had a brainwave. I could mod my oppo 93 with a vanity board. Feed the Datasat aes/ebu and bypass the downsampling issue.

Yes, that is what some people are doing with a Trinnov MC. You can get a custom S/DIF -> DB25 cable made for use with the Datasat.

Yes, that would work. I wish Theta had a method to legally get greater than 48/16 out of the Digi out card. Without the proprietary Mega-link that Theta once had in development, this is unlikely to ever happen. However, with your processor it is possible.

I decided that that I am happy using the Gen VIII just for two channel and passing the Casablanca channels with unity gain. Theta may be squandering this piece. It should have been thoroughly reviewed and be selling a lot better than it is. Take a look at the specs for it. If you were shopping just for an analog preamp, a lot of the most expensive ones don't' have these kind of specs. SNR for the Analog outs balanced is greater than 120db. Cross-talk 140db.Less than 0.0007% for THD+Noise This the analog section! Theta Gen VIII.JPG 75k .JPG file Take a look around at some of the other gear. You may have to ask for the specs for some, and they aren't this good.

There are so many lifeless and sterile audiophile products. This one surprised me more than any other product I have owned. I expected it to be good but didn't expect it to be as good as it it. What impresses me most is that I am still as happy with it as when I first purchased it. I have compared to the Oppo 95 which is a fraction of the price but give great sound. It's immediate and apparent, that the Gen VIII is several levels above the Oppo even with just Red book. 24/192 tracks are truly stunning.

You have to consider that you are getting a very good analog preamplifier section as well as a dac which is why I mention the analog section. Many, miss this crucial point. Using the analog outs of most dacs is no where near what this product can do.

Yes the Premium is a newer design but not nearly as good as the Xtreme dac. I would buy at least one Xtreme card. Take a look at Cannga's take on post 2572 and 2590 of this thread. That may help you.

Absolutely!!!

My CB3 HD connects via digital AES/EBU to the Gen VIII.
My Bryston BDP-1 Media player connects via digital coaxial to the Gen VIII.

Since movies are over HDMI, the CB3 HD "downsamples" to 48k. But almost all movies are originally mixed
at 48k anyway, and even though the Extreme DACs in my CB3 HD are marvelous sounding, the Gen VIII is in a whole
another league!
