I appreciate everyone's responses, and I am aware that specs are not always a good indicator of what sounds best. I'm trying to avoid some things I was not impressed with on my UMC-1. The noise floor wasn't all that great. Using an analog input was horrible due to a mute circuit used on the converter I believe. This made my source unusable. I would also like to know what max output levels of the pre-amp is for matching to amplifiers. While recently trying to troubleshoot a newly developed HDMI handshaking issue with my UMC-1, Emotiva had recommended that I get an MC-700. They also said they do not have electrical specs to provide. Now I'm seeing posts about the MC-700 having HDMI handshaking issues, so this all makes me a little hesitant. HDMI handshake issues are going to come and go; it's the nature of the beast. The MC-700 is leaps and bounds better than the UMC-1; it's 2 generations newer.

Not to mention one will spend more time and effort trying to over-analyze and see if it's a good fit, than one would if he/she just tried it out. If it isn't acceptable, send it back. Edit: Of course if you're international, then trying it out really doesn't work. Really only practical for the Yanks.

The MC-700 has had a bit of a rough start with some bugs being reported. Apparently they are working to patch them and have released some patches. But if you were dissapointed with the UMC-1, I would wait till things get sorted out. As for matching to the amps, unless you are running some low gain amps, you're not really going to have trouble with the MC-700

I know of very few HDMI switching AVR's and preamps that have not had their share of HDMI bugs at launch. That's just the nature of HDMI. You're dealing with a company that has a respectable warranty and great support, with a decent return policy. They've pulled out a lot of the stops for you already.

Does anyone know the voltage and impedance of the RCA outputs on the MC700?

What DAC's are used in the MC700?

What DAC's are used in the MC700? I believe when I looked inside mine it was the Cirrus Logic CS42528 Cheers Gary

And yet, most components that measure poorly perform poorly. Meeting well-established thresholds for audio specs generally ensures that at least the component is designed properly and is likely to function adequately. And some companies that fluff or mis-represent their specs to make them sound like they're over performing when, in fact, they don't sound that good (but people who are spec driven will swear that they sound good; sometimes without even hearing the product). I'm on the other side of DYohn. Some components measure good and just never wind anyones clock. While some pieces which don't measure as well are popular, have a following and perhaps even hold value well as 'pre loved' components. The key word in DYohn's response is Threshold. If specs REALLY could be relied on to provide a go / no go for a component, you'd hear about it. Ain't happened yet. Besides, there are indeed thresholds. Humans have known (to some extent) tolerance for distortion. So, you simply stay under that level. Some persons are sensitive to amps which feature excessive (Third Rail Alert!) Negative Feedback. But even with that proviso, some Zero NFB amps advertised as such never got Any Traction and are gone from the market. Bruno, the design drive behind nCore (HYPEX) swears by huge amounts of NFB. He has a following. Go Figger. Lets say, just for the sake of arguement that you tried an MC-700 and it just didn't make YOUR cut? Would all the good specs in the world make a difference? Do you purchase based on specs? And as for something like a DA convertor? 2 implementations of the same part yield different (audible) results. Choices involve circuit topology and even down to the parts used. Parts Ain't Parts. Even the choice of Circuit Board material matters. Or would you go in search of the Magic Spec which caused the fail? HiFidelity is a history lesson in getting better without ever reaching Perfection. Some circuits in use today are very old. 'D' amps are decades old. Macintosh makes about the 5th or 6th revison of the MC275 which is a Legendary amp. audiokarma.org/forums/index.php?threads/mcintosh-mc275-versions.324969/

I've got a Bose sound system in my car and I have no idea what the specs are but regardless of what they may be, they just don't sound very good.

Hello, maybe I can use this thread to ask a similar question: How does the sound of the MC700 compare to an OPPO 103? Will it sound as good as an Oppo 105 (or better)?
Is the build in room corrrection&equalisation comparable to a Dirac processor? What are the shortcomings? The question that follows then is, if a NanoDVR with Dirac would be a better choice? And that leads to the question of how the MC700 compares to a NAD T758v3 comparing only the Pre-out. I have an OPPO 103 feeding a Parasound PSP1500 with 3 Parasound Amps driving 6 Canton RCL (2 combined for centre for symmetry) and a CD transport with a Parasound DAC2000 for Stereo.
I want to upgrade my 5.1 chain where room correction might be more important than fidelity.
