You'll find plenty of people here with first hand experience with the umc1,mostly good but some issues.I have no doubt you'll get the most info on this unit right here.I was just trying to get ya to the products page cause that's a great place to start,not to give you a hard time.

Thanks Moe, I do appreciate that, and I do understand exactly the help you're trying to provide me. I'm glad that we both get that sort it out in a very respectable manner.
You have a great evening Moe,
Bob

When I asked Lonnie this question last year, about including DSD, he said that they were talking with Sony, but he did not think Emotiva would license it because Sony was being totally unreasonable and inflexible with their demands in the Licensing Agreement. The Cirrus chip natively supports DSD, so the UMC-1 is fully capable of decoding, if Sony changed their stance. Since nothing is mentioned in the Product Page for the UMC-1, it is highly doubtful DSD over HDMI has been included in the list of codecs licensed and supported. Sony has a long history of being hard to work with when it comes to their intellectual property. Oops! I just noticed I was posting this response after taking several potent pain pills the other night. My brain was even foggier than I thought it was. To correct my error in the above post a little background is needed. Sorry for the confused state of my mind. I hope it did not confuse to many Lounge members. Back when the ERC-1 and the UMC-1 where being discussed during the final stages of introducing the ERC-1, quite a few people were asking if the ERC-1 would be able to play SACD disc. This is when I called Lonnie asking about including DSD functionality on the ERC-1 since the Cirrus chip set being used in the UMC-1 natively supports DSD. So it was the ERC-1, not the UMC-1, that was the root of Lonnie saying Sony was being totally unreasonable in negotiations for the DSD Licensing Agreement. The UMC-1's ability to decode DSD has never been in doubt. As mentioned above, the Cirrus chip natively handles DSD. Please accept my apology for getting the details scrambled in my drug induced foggy state of mind. This error has been eating away in my subconscious mind knowing I had posted something that didn't make sense, so today I finally went back over my posts to see what I had said. When I found it, I felt I needed to correct it just in case anyone was confused by it. Sorry.  Yeah, I'm still confused. When I play SACD via hdmi, the UMC displays "Multichannel PCM 176.4khz". My sony will output both pcm and dsd, but there's no setting to choose one or the other. it will determine what to send based on its communication with the processor (apparently). So the only way I'd know is by what is displayed on the processor. I guess it doesn't matter that much to me, but I am curious. Now the bigger question is: unless I'm missing something, I have only two listening modes when playing SACD over hdmi - "Stereo" and "Direct". Does "Direct" in this case bypass the room correction EMO-Q processing? I have not touched the room eq settings yet to test myself - waiting on the sw update. |

Thanks roadrunner...I am sending a DSD from my Oppo and the UMC takes it and converts it to PCM for processing. What Nick said did not make sense to me , but does if he is referring to the ERC.
And yes....STEREO simply means the UMC can apply post processing to the signal (EmoQ, bass mgt, etc) and DIRECT means no processing is applied to the signal.

Just for clarificaiton because I see some confusion here. The Cirrus chips no longer support DSD. I don't know the reasons behind this, but we were just told by Cirrus that they will no longer be supporting DSD. So it is not a matter of licensing on our part, it is just the coding within the chip is no longer active. Hope this helps.  |

Have you anybody specification of THD, IMD, signal to noise, etc... on all channels of UMC-1?

The prior statement about NOT doing DSD applied to the ERC! |

Lonnie Did Cirrus give an sort of an explanation as to why they will no longer be supporting DSD? Is this something they did by notifying you that as of a certain date they would be disabling the DSD function? ...and if so what is the cut off date? Would this mean that the Cirrus chips you already have in stock will be able to accept DSD for native processing? Would the UMC-1's already in our hands be able to handle DSD natively? What are the long-term implications for SACD via the UMC-1? Inquiring minds like to know? ;D ;D ;D |

If I switch to LPCM, it displays LPCM. Is the Oppo wrong? The prior statement about NOT doing DSD applied to the ERC! I thought this thread was about the UMC-1 and DSD support? The UMC-1 uses Cirrus chips, Lonnie says the code for DSD is dormant in the Cirrus chips so the UMC-1 doesn't process DSD at all, nada. I think it is entirely possible the Oppo could be displaying DSD even though it is actually sending PCM. I wouldn't put too much stock in that display. Oppo, as good as they are, also have firmware bugs. I own two Oppo machines. I love them. I'm not knocking them! I would put more stock in what the UMC-1 display says as that it is an indication of what it is actually receiving. I actually think it is praiseworthy of Oppo if they check when sending the DSD stream to see if the receiving device can actually handle it (since so many things can't) and auto change to LPCM if the check comes back negative. That's better from a support standpoint rather than the signal being silent or a blast of digital noise. We know that HDMI can negotiate video display resolution between devices so I don't see why it can't negotiate a compatible audio codec as well? Frankly, I could care less whether the stream is DSD or PCM as long as it is full data rate digital over HDMI I'm a happy camper. I am in the camp that doubts anyone can hear the difference between PCM and DSD. Just like I don't believe there is any quality difference between $2 HDMI cables and $100 versions. If it bothers you about the Oppo DSD display, why don't you contact Oppo and ask them what's up? My experience is they are very responsive and may be able to shed some light? -CB |

Oppo confirmed DSD via HDMI. I will pose the question to Lonnie.

Wow this is sucking more and more. I wanted to try SACD out and was planning on it with the UMC.

but I just read DSD is not working with the chips. This gets more confusing, wish I could just get the damn thing and try it out for myself

I don't know what SACD player you have but you will be able to either PCM it or pass it to the analog inputs. We know the UMC will take both of those.

I suppose it would be good to know for sure.That said,a few years back,myself and a few friends tried to tried to pick a dsd feed,none of us could hear a difference.
As to the $2 vs $100 hdmi cable being "same quality"I dunno,but same audio quality,maybe.I think about $10 gets you a good cable,guage,shielding and longevity being a good thing.
I've listened to most of the sacd's I have on the UMC,they sound great to me.
