Everyone, Dan and company are busy preparing an updated XMC-1 page for Monday, however in the meantime I've been given the go ahead to share the XMC-1 AP test data with all of you. This is not a cherry-picked unit. This test data was gleamed from a random XMC-1 pulled straight off the line, and that will be shipped to an eager customer soon. The numbers you're seeing here represent those of actual production units and not a test mule. Also, look for the manual on Monday. Have a great weekend everyone! Attachment Deleted |

Looks great! To bad I have no idea what most of it means

Thanks! I don't recall ever seeing that much detailed test data from a manufacturer before. So good on ya!
Is that all you guys can share before the weekend? No final specs until Monday? Can you confirm what many have asked since I think there was conflicting info given about whether just two channels are fully balanced or if they all are?

Looks great! To bad I have no idea what most of it means : ( The first eleven pages are measurements of the two fully balanced signal paths: Pages twelve through twenty one have measurements for the eight unbalanced channels. Pages twenty two through thirty two have measurements for the balanced A to D Converter outputs: Pages thirty three through forty two have the measurements for the 7.1 balanced inputs to 7.1 balanced outputs: Pages Forty three through fifty five have the measurements for the Main DACs HDMI PCM 7.1. Pages fifty five through sixty seven have the measurements for the Coax Digital In : Main DAC Level. Pages sixty eight through seventy nine have the measurements for the AES/EBU Digital In : Main DAC Level. Pages eighty through ninety one have the measurements for the Optical Digital In : Main DAC Level. |

Andrew thanks so much for this AP test information on the XMC-1.
Were any AP tests run on the Emotiva UMC-200? I didn't find it on the site. Maybe I missed it.

Thanks, Andrew. Performance looks phenomenal!  Now comes the difficult wait for my turn in the reservation queue.  |

Andrew, did anyone else have one for review - S&V, Audioholics, etc.?

wow...
According to this, Balanced to Balanced 2ch THD and SNR are better than XSP-1 !!??

Awesome! Glad to see new AP results. That's great!
Thanks for posting.

Well it seems s*** is getting real. Good looking data. Thanks for the post Andrew  |

Talk about laying it bare!
So uh, those specs are looking mighty fine eh?! Congratulations. I barely understand it but I do gather by the numbers and graphs it is knocked out of the park! I see some of the SNR's in some frequencies going in the high end of -135+ db A-weighted!
Question on the differential reference. Is it differential reference on just the front two outputs (balanced differential) or is it ALL the channels?

It is really awesome!
Do you have any plans to support ATMOS?

the XMC-1 AP test data. Also, look for the manual on Monday. Why is the 2-ch of the XMC-1 so much better than the Gen2 XSP-1 on several of these results? (I though the direct analog nature of the XSP-1 makes it the best of the best for 2-ch stuff?) XMC-1 Phase: - 0deg +0.5deg (Win)  XSP-1 Gen2 Phase: +20deg -40deg (Fail)  XMC-1 SNR: >-130db (Win) -15db? (Why so low?)  XSP-1 Gen2 SNR: -105db harmonic distortion (Fail) +10db? (Why so high? Driven into clipping?)  XMC-1 THD vs FR: <0.0015 at all frequencies (pretty good) (Smoothing?)  XSP-1 Gen2 THD vs FR: <0.0004 below 3khz (winning), >0.0015 above 19khz (Fail) (No Smoothing?)  XSP-1 Gen2 THD vs Vout: 0.0005 below clipping (Winning)  XMC-1 THD vs Vout: Less Vout and slowly increasing distortion above 0 compared to the XSP-1  XMC-1 Impulse:  XSP-1 Gen2 Impulse: (Inconclusive because of scaling differences)  The scaling differences in these charts (UMC-200, XSP-1, XMC-1) makes it really really hard to compare directly. The poor Phase and SNR of the XSP-1 is disturbing compared to the quality of the XMC-1. Why is that?I thought the XSP-1 was a wire with a $1000 volume knob attached to it (i.e. as direct and as simple a path as you can get), how could it EVER measure worse than a digital processor with all those extra chips and circuits and tuners etc etc inside it? |

The hometheaterhifi review shows the XSP-1 doing this, no harmonics to be seen so I guess the Emotiva report is showing the XSP-1 in a less-than-favorable light (you might want to correct it).  |

I'm impressed with these test results.
Makes you wonder how much more can be done with the RMC.
