Great info Norm, thanks.

I was wondering if you happened to catch what the actual Silicon Optix chip was, or if they gave you new jitter specs for the new Jitter Jail II
Your impression of it, if possible, would also be appreciated.

Thanks In Advance
Marc

Yetis. Apologies. I checked my previous workings and need to correct my estimate. You were right. It was/is £2050 incl engraving. That's using shielded mains wire for the internal power and Audio Note internal speaker wire for the XLR (Cardas rhodium silver) wiring. Furutech IEC and Cardas rhodium silver binding posts. I didn't plan on changing the wiring provided by Hypex. Outsourcing the CAD work for the panel milling would add a bit more.

Having spent quite a bit of time over the weekend looking at fine-tuning my sub crossover and delay settings I'm surprised by your last statement. The Aerial Acoustics 9s drive relatively low but I would have thought that a sub or subs, properly setup, would aid in delivering further low-end and dealing with room modes. I now have my CB crossovers set to 100Hz / Slope 24 (both Hi and Lo) / Butterworth whereas before I was using Full/LP set at 80Hz. The latest settings are better than Full/LP or running the Andras alone (despite being rated -3dB @ 18Hz). That said, bass is all about the room and every room is different (although one does need to activate those frequencies in the first place).

If I read Marc correctly, sub management and a Gen VIII is not mutually exclusive. It is interesting that you came to the conclusion to run your stereo system this way.

Tyree91:

The chip to implement Jitter Jail II actually comes from Silicon Labs and not Silicon Optix.

As to availability, you are correct, the Casablanca IV upgrade will be available in 60 days. Prometheus will be available in early January.

Each room and system are different. My room was purposely built to sound great for audio. And as my very best components are at the front left and right, apparently the most musical bass is simply at the front left and right without any subs - not the best most massive bass for home theater and movies, but the best most musical bass for music.

Any idea how complicated installation is for those that are a long way from their dealer and need to do it themselves? I guess we could be guided through it but does that mean we void warranties and such?

(I refuse to deal with Absolute Sounds or dealers in the UK here ever since the former had my DaVid for almost a year and had to replace the Pioneer mechanism 3 times in succession. Long time ago but I will never deal with them again. I buy all my gear in the US.)

I'd love to demo the Prometheus. Actually, maybe I don't want to. Maybe staying blind to the performance upgrade from my Krell FPB is a good idea for a bit longer!

Steve

We will be doing the upgrades at our shop here in NJ for some of our customers. Others who are super techies will probably take this on by themselves and we would have the upgrade kit sent directly to them. Others who don't want to mess with it can certainly send it to Theta with the RA # we will generate to get it done at the factory. Lots of options for everyone.

Sounds like I know what everyone is putting on Santa's List smile.gif

Or on our Hannuka list!!

For me, Craig will give me an RA# and I'll likely ship two states over to ATI-Theta in CA! Meanwhile, I still will have my Theta Generation VIII Series 3DAC playing away for both music and movies until the CB IV comes back!!@@@biggrin.gif:D

Does anyone know if the new Dirac upgrade price for the cb3hd includes the Measuring kit for Dirac. Eg, the mic, mic pre, pc software? If not, any ideas on price for the Dirac calibration kit?

Many months ago we were informed on this thread that the MSRP price including Dirac includes all you need to get Dirac up and running on the Casablanca, except that you need a PC to do the programming. So it clearly must include software and a mic.
post #5503 of 6787
Indeed. Software and microphone are included. Please be advised that the setup is not currently Mac friendly.

Does it stamp out the left rear channel popping noise bug?

Also, does it report back to a connected HTPC that it can receive multi-channel (I'm not doing this so apologize in advance if I described the issue incorrectly).

You bet. They tell me the Software for all appearance is Bug free. The 60 days is just to make sure they release as perfect an upgrade as possible. Norm

Craig, it's Joe in PS, CA. I sent you a note about the new version IV. I'm interested...so let me know when it's available...sent me an email and we can work out the details....thanks

Ahhh. I was hoping it was software so that the Gen VIII could also benefit from the new Jitter Jail II. Jitter Jail II is not as critical with the Gen VIII if you use a USB to SPDIF converter which controls jitter before the Gen VIII ever sees it. However, if the Gen VIII ever had a USB input, the new Jitter Jail II would be very useful.

But, yes, they will be upgraded in due course. At least they aren't bottlenecks. It would be nice to hear the Prometheus... Hopefully it will indeed be brought to market.
Well amps are kind of a bottle neck now. I bought my Mcintosh amps partly because the signal to noise was high enough not to limit the high resolution so much. Stereophile,"The MC501 is one of the few amplifiers that can match the theoretical dynamic range of such hi-rez digital media as SACD and DVD-Audio." Many of the older amps, really don't have the specs to pass much greater than 44/16. If you really evaluate the situation, we are a long from real 24/192 playback so I would not be too concerned with 24/192 dacs before upgrading amps for sure. Even if you ignore the frequency response, the dynamic range is lost on many of the older amps in particular. The new Prometheus amps, also have the kind of specs to allow much greater dynamic range than many traditional older amps and you will not get a hernia lifting them.

Jeff

I hope it is not completely unfriendly to Macs.

I was counting on connecting to the CB IV via USB from a dual boot Macbook Pro with Bootcamp running Windows 7

Should this be a problematic setup for Dirac, I surely would like to know beforehand if possible.

Jeff can you be more explicit? I am exchanging emails with John on this topic. The usual setup for this sort of acoustic work is a microphone (typically XLR) into a pre-amp connected via USB to the computer and either digital coax or analogue from the pre-amp to the CB. I for example, use a Roland Quad Capture and top quality mic from iSEMcon. John mentioned the supplied mic "will have a USB input on it which feeds the computer". This setup sounds very odd. You've still got to deliver a sound signal to the CB from the computer. Also, I assume the mics will come with INDIVIDUAL calibration files. General calibration files are rather useless.

Please let us know which mic (and pre-amp) are included in the package.

Lastly, at the moment when running a digital connection to the CB from the preamp, the CB generates a loud "bump" (as opposed to a higher pitched pop) when the sine sweep signal is initiated. It does not do this when the received signal is analogue into the analogue inputs. Obviously this is not ideal when one is recording and analysing the response into the mic. Has this been tested?

Thanks. All in good time. :-)

BTW I continue to very much enjoy the Shelby Lynn SACD you recommended. Any other recommendations of such high-quality recordings appreciated!

Oh one other little "interesting" thing. The latest firmware for Oppo players (which by definition will include the Compli series in the end) has removed the ability to play SACD-R. So no more playing copied SACDs. (I had duplicated all of mine so as to preserve the original disks.) Accelerates one's to not playing disks at all.

I have the Datasat RS20i and Dirac software talks to this via the network, so I'm going to hazard a guess this will be the same with the cb3hd. Seeing as you have been told you will be getting mics with built in USB pres.
post #5514 of 6787
What if any new codecs will be available in the new CB4?
post #5515 of 6787
I'm not sure what would be involved. I guess you need a computer. I don't have a laptop and my desktop is in a far-away room. Will I be out-of-luck?

You could always buy an inexpensive laptop for a few hundred bucks, even less. You will need a PC to program Dirac.

Or you could go through the pain of moving the PC over to the CB!V to get it programmed, and then move the PC back thereafter.

Of course, this does not mean Dirac stinks or is great. Just some data points.

His camera reviews are helpful, though.

Oh no, Ken Rockwell doing audio reviews. As if his camera reviews were not already biased enough.rolleyes.gif
