This may be a question for a later date, but what will Dirac be able to do that cannot already be done with a good working knowledge of REW while utilizing the vast amount of paramaters available to tweak on the XMC? DIRAC can adjust in the time domain while REW cannot...net, it can clean up the impulse response. Mark

Jim, I would think that selling the other gear would be a wise move. You already have a very capable universal player (Oppo 93) and you could easily add an Emo phono pre with the money generated by the sale of the USP-1, ERC-1, UMC-1, and the XDA-1. If you were feeling particularly extravagant, spring for an Oppo BDP-105D and check out the benefits it offers (Darbee!!) Time to cull the herd, I say....<g>

OK. Received mine yesterday. Set speaker distances (which is to the inch BTW) and levels via my trusty old analog Radio Shack meter. Left my USP-1, ERC-1, UMC-1, XDA-1, Paradigm sub controller (phase, LPF, Level) out of the system. Sounds so good already that I'm considering selling all this gear, just using the Oppo for disks letting the XMC-1 do all the decoding. DSDs decode very well, sound amazing. I have loved the USP-1 especially and now have no phono preamp, but what do you all think about this radically reduced signal path idea? Any reason to keep the ERC-1, or the others? I found it difficult to understand how the various trigger option are "and'd" or "or'd" together. Trying to trigger my XPA-5 which handles the center and surround channels. I couldn't get a trigger to work based on speaker use exclusively without having the "main power" also selected. But that seems to trigger it whenever main power is on regardless of speaker use. Not a big deal, but the final manual needs to be a bit more specific as to how these selections interact. Keith? Also got an audio glitch (sub-second noise) via the Oppo and XMC-1 at the end of a DSD CD after the last cut. Seems like the stream wasn't shut down gracefully. Haven't tried to reproduce this yet. I think the usp1 is certainly at risk Jim ; redundant with the xmc1's great analog stage and you can replace its mm/mc impedance switch with something that has more range/ better matching with the loading - emotiva.com/sites/default/files/styles/product_main/public/xps1_front.png?itok=ZflnEcmQGeebo has a handle on the trigger setup it looks like ; maybe try a pm

I've been looking at the xps-1. Should be fine for me. Messed with the trigger setup again today. but no joy. I'll ask what geebo did.

Worked a bit more with it today...
1) There is definitely a problem with either the OPPO BD-93 or the XMC-1 with DSD decoding. If I set up the OPPO to pass the DSD stream so that the XMC-1 can decode it, all is fine until the end of the disk. When the OPPO stops, there is a brief audio noise burst (glitch,) and the XMC-1 switches modes back to the default for the device. When I let the OPPO decode the DSD (converting it to PCM,) all is well and the XMC-1 remains in PCM mode when the OPPO stops. Seems like the OPPO may not be terminating the DSD stream gracefully? Or a handshake problem?
2) Also, when the XMC-1 is decoding the DSD stream, the zone-2 outputs output only the left channel. This would seem to be a problem with the XMC-1. The Record outputs are a good stereo mix down. Both these tests were with a CD containing a 5.1 DSD track, and the XMC-1 was in DSD Direct mode. When the OPPO converts the stream to PCM, the zone-2 outputs are fine.

Might I ask which SACD you played?

Good question from Jim, and have you played more than one SACD? Do they all 'glitch'? Be nice if someone else could try this on another player (though the same would be helpful too).

I verified #1. Jim, when your Oppo is playing a track, try stopping the Oppo and then pressing stop again and see if this also gives you the same result as it did for you at the end of the disc. I have the same Oppo player as you so hopefully if you can repeat this, we can report this to Dan/Lonnie. Also is your Oppo's firmware this version: BDP9x-80-0513 ? Being able to repeat a condition is key so Emotiva can replicate.

I'm not sure, but I think zone 2 can only output stereo PCM. I'm surprised you are even getting one channel. It's my understanding that XMC 1 does not convert DSD to PCM.

This is my understanding as well, but you can send either DSD or PCM from the Oppo, and then the XMC-1 determines which one and what to do from there.

No audio glitches when the XMC switched from DSD at the end of the SACD.

It makes me wonder if the locking/unlocking of DSD from the BDP-93, as Jim says, is not as graceful as your BDP-103. I'm going to try out my BDP-83 in a few minutes and see how it does with the DSD stream.

Update, my BDP-83, does not have this problem when playing SACD's, so I can only assume its the BDP-93 that is not locking/unlocking on the DSD stream nicely.

I think we can safely assume it's the BDP-93, since you've confirmed no problem with the BDP-103 and myself with the BDP-83. Thanks for the input!

Might I ask which SACD you played? Tried it with two, same result. Carol Kidd, All My Tomorrows. Dianna Krall, The Girl In The Other Room.

Being able to repeat a condition is key so Emotiva can replicate. Checked the firmware version BDP9x-80-0513. Tried a manual update, but says it's the latest. Thanks for looking into this. I haven't had time to try your suggestion, but will when I get a chance. It's definitely repeatable as I described. I tried pausing or stopping (can't remember which) and restarting (with Resume enabled,) but no glitch there. Will have to try your exact sequence.

This is my understanding as well, but you can send either DSD or PCM from the Oppo, and then the XMC-1 determines which one and what to do from there. Yeah, I wondered if it was supported, but definitely got one channel. Thought it might be a connection or amp problem, but reversed the leads at the XMC-1 and it went to the other channel. Also, the Record outputs are OK with DSD Direct...
