Watched Andor Episode 6 last night, the Eye and the Tie fighters sound awesome in Atmos 5.2.1 via the XMC-2. I have no issues with my XMC-2, although I do perform a cold start once a week or so to clear out any junk. Cheers Gary I thought it sounded great as well! 🚀 But … how do you setup .1 Atmos? |

I cold start mine everyday…via a home kit based power point switch. Much more stable than in the past. Also the network stack frequently just gives up so I have this on a VLAN with not much other traffic…also helps.
As for the frequent video/hdmi issues I just switch everything thru an HDFury Vrroom and only send audio output from the HDFury to the XMC-2
Maybe 3.0 will fix some of this but I’m guessing not all….my wife just told me get a different setup but a trinnov is out of my budget…so will see what happens. Still have the trusty XMC-1 that works well.

The cost would have been amortised by father time by now and depending on 3.0's efficacy could be still giving value  isnt hindsight great  |

Even after the questionable decision to use a 40% card on an RMC-1L before the card expired, it's still very useful. |

Recently the usually dead middle phantom center channel effect in stereo has drifted to the right in my system. I tried everything with no luck. Then I did a hard restart and the phantom center was back in dead center. I do wonder what causes the drift, but when it happens a restart always fixes it. |

I thought my ears were playing tricks on me. It's not just a phantom center channel level issue. |

Chip fabs are VERY expensive to set up... so not very many chip manufacturers have a spare. ("Expensive" as in "more than the annual budget of a few small Caribbean countries".) However there are several very fine DAC chips in the world... So, unless you're obsessed with a specific vintage and out-of-production chip (ahem), then there is no real problem beyond a bit of redesign work. "The Lampizator" is an interesting fellow to be sure... As you might guess he tends to think that "everything is a little better when you add a vacuum tube". So, if you really do like those TDA1541's for some reason... As Lampi would say.... "just don't forget to add the tube"...   Yes... he really would say that... (And maybe a heat sink.) I would note, however, that many of Lampi's modification projects of vintage devices are themselves somewhat dated... (So not only are we reading his take on the results... but it isn't always in comparison to current technology.) Didn't AKM have a fire? If so, it'll take a LONG time to get the fab back up and with good yield.....Sort of depends on how bad...... Ive been thru all sorts of fab malfunctions, including a massive chemical spilll......Film at 11 But AKM might have a 2nd source all staked out to continue. It is possible they use the SAME mask set with some process variation which means a New part number but no real change in capability or specification. This is the responsible thing to do. A 'single point of faillure' means that SOME companies simply will NOT buy your stuff..... Most manufacturers will issue a 'reference board' to show whatever in 'best light'. For me? Give me a TDA1541 www.lampizator.eu/lampizator/TDA1541%20corner/TDA1541.html |

Yes.....FABS are Very Very Expensive. Priced at the BMW Level....Per Square Foot.
I've been on the ground floor with several new constructions and while you know it is $$$ you have no real idea.
A brace of implanters (you can NOT survive with just one....or even two.....Cost in the millions each.
Steppers? Just price out one of the LENSES than look at the several foot long optic path, the half ton granite MicroFlat it is all built on?
Many fabs world wide do OTHER PEOPLES Designs. As long as the technology is compatible or can be adapted. If I owned ONE fab that
made something very unique and desirable? MIght not sell as well as you'd hope. SECOND SOURCE is a form of insurance policy to ensure
an UNINTERUPETED supply. Accidents happen and the recovery is always a PIA and can be massivly expensvie. My last fab was down for
over a month after a worker CUT INTO a double-containment HF line. When it comes to liquid chemistry, you'd have trouble finding something
worse to cut into......
And you ain't lived until you've seen a 6 DIGIT MONTHLY Electric Bill......And water bill. And the bill JUST for the thousands of cubic feet of Nitrogen
needed.....Not to mention a dozen specialty gasses......WITH the special place to store them.....with blow-off panels......and all the rest.
You do not BUY a spare......you basically LEASE it. Some companies, like INTEL, have multiple fabs. I've been IN 'EM....But not all fabs made the
same stuff......so when the next generation arrives, they either adapt existing or build new.....with room to grow / adapt to new tech and have room for
the new tools needed WITH The new facilitization / processed to go with......
ANY company without 'plan B' is asking for trouble.
The 'other' fab? It is called a 'FOUNDRY'.......
BTW? TI is building a 300mm fab.....That is with Silicon Wafers of 1 foot DIAMETER......This has the potential of nearly 4x the product PER WAFER as a 6 inch wafer.....for not really much more work.

I doubt EMO uses any proprietary semiconductors.....
Companies also may use foundries for SEASONAL demand. You need more of a given device than you can make by the promised delivry date?
Turn 'on' the foundry and problem solved....

Did you have a problem with your RMC delivery? |

Ok, thanks for the explanation. I have experienced this as well, have even gotten up to ensure the center channel was not producing sound (on several occasions). |

Ok, thanks for the explanation. I have experienced this as well, have even gotten up to ensure the center channel was not producing sound (on several occasions). The phantom image is a function of any number of channels that is trying to produce that image. In a good system, it will be wherever those channels are trying to produce it. The more equal the channels, the more accurate the image - Phase, amplitude, crossover, delay, frequency response - in any system. I have a recording where the sound is coming predominately from the left front channel, but the image is coming from the an area near the right surround channel - about 90 degrees right from center. There are a lot of tricks in the trade. KeithL is right concerning most phantom imaging with 2 channel stereo imaging. However, I have 2 channel stereo LP's that produce imaging in areas other than between the left and right front channel. That L-R phantom image that produces a center is also not perfect. There is a 1.8Khz dip in the image. Just do some research. It's an interesting field. You may learn more than you want to know, or it could be fun. |

Turn 'on' the foundry and problem solved.... What kind of EMO semiconductor problem are you trying to solve. It doesn't look like they are having a problem with delivery. Did you have a problem with your RMC delivery? Please read up on the different DACs referenced elsewhere in this thread. Someone referenced a problem with one of the fabs......This should NOT be a problem IF the company follows good or maybe 'best' practices and has a foundry already qualified to make their product. I'd wager that EMO hasn't any proprietary semiconductors in anything they make. It is a matter of How Many you need. A single 'lot', in manufacturing terms, can produce thousands of good devices......all of a single type. If EMO needed that kind of numbers? You'd really get the bill. Just getting a new device qualified, even maybe, if just a variation on an existing device is time consuming and costly...... Nelson Pass had a special run of a special transistor made FOR HIM (A VFET, IIRC) and he made a certian number of amplifiers and kept some for spares and for the DIY market.... Point is? Part of the 'chip shortage' is real...and I suspect some is 'fabricated'.....If you'll pardon the expression...Some materials MAY be more difficult to obtain or more expensive while if a facility got hit BADLY by COVID than it is possible they simply would not have enough 'help' for all shifts in all areas of manufacture......Not EVERYONE can do all jobs. It is specialized to a degree so while I was qualified and taught implant and metalization, You wouldn't trust me around a stepper.... A photographic instrument.... |
