... So we are hoping to have the revised software by the end of the week. Oh really?! That's interesting news indeed.

I had a post written late last night, but my internet connection went to bed before I did and it disapeared. Let's see if I can remember what I wrote... Now more than ever, I think it's important that Emotiva communicate some things clearly. The issue list at the start of this thread is now over two months old (with a number of the items dating back well into last year), and Emotiva has been aware of it from the moment it was posted (I've sent them a number of e-mails to ). If they have come far enough with the firmware revisions that they hope to have final code in hand by the end of this week, there should be some information readily at hand - either notes regarding the "Support" issue list, design team notes, or something from the firmware testing that must be going on or at least planned. Anyway if I decide to go with the non-entry level any comments on my earlier question as to the differences between the MMC & DMC? I only noticed the HDMI built in to the MMC versus and add-on on the DMC and the balanced outputs. Am I missing anything? The MMC-1's internal HDMI switching is functionally the same as the external HDMI switching available for the DMC-1 and LMC-1, as it does not support digital audio or video transcoding. As far as I know, the only differences between the MMC-1 and DMC-1 are balanced pre-amp outputs, internal vs. external HDMI switching, front panel design (MMC-1 matches the LPA-1 and IPS-1 amps), and the remote controls (DMC-1 has a MX-500 universal remote, while the MMC-1 has a non-universal remote).

I hate to bring this up again, but it is really confusing me. I know this has been brought up here, and on a "certain other forum", but this whole issue of LMC-1 having a hiss/higher noise floor is puzzling me. I like the administrator, plan on purchasing high efficiency(91-95 db) Axiom M80 speakers. I know this has been brought up before, but I have yet to see any extensive explanation of this....because the lmc-1's noise floor specs are rather good from what I see... I see that one theory proposed is that because testing took place at avr123 forums, only low efficiciency rocket speakers were used. I know nobody here initially made that thory, but I find it hard to believe that a company would be that dumb. Besides, correct me if I'm wrong, but isn't noise floor a measureable stat independant of other variables like speakers? I know this post is confusing... but I don't think I'm the only one who has these questions.

To clarify, while I did hear some light hiss on my LMC/M80 system, it was not enough on its own to send it back. It didn't help matters, but it wasn't that bad. My Pioneer/LPA combo is dead quiet when it should be; quiet passages, between CD tracks, or when no source is playing. Never any hiss, even at max volume. The LMC/LPA combo had some hiss. I heard this hissing on three occasions. All three of the times were during the afore mentioned places when the volume was at a level that would produce 90+db peaks in music. That is to say, pretty loud. Only my M80's hissed. Neither VP150 nor my M22's made any noise at all. My wife even asked, 'what is that?' during one of the transitions, so I wasn't imagining things, nor had I told her I had been hearing some hiss. It was not 'tape-deck' hiss, but it was there. A review of the MMC-1 was recently released, and the reviewer comments that it also has a higher than usual noise floor. His description of its hiss is very similar to what I experienced with the LMC-1. From Audioholics' review: Of curious note, I heard the hiss when using PCM digital from my CD player, but also when using the 7.1 analog inputs when listening to a SACD. I did not try a 'source direct' on one of the stereo analog jacks. www.audioholics.com/reviews/processors/emotiva-reference-mmc-1-av-processor-review

There is certainly something going on with the noise floor that is revealed by higher-efficiency speakers (one possible drawback to a beta test that employed lower-efficiency Rocket speakers more than any other brand).
The LMC-1 lacks a "source direct" mode (also sometimes called analog bypass) for the stereo analog inputs - the 7.1 input is the only signal path that allows an analog "source direct" condition. As a result, your SACD testing helps confirm that the noise floor is somewhere in the common analog section (after the output of the DAC's) since it affected both PCM inputs and the 7.1 analog input.

Thanks Gonk, that was my impression as well but I hadn't delved into the manuals as many have. Now I have to decide if the remote and balanced are worth the extra $100. Will I see a big difference with the balanced versus the unbalanced?

Thank you, I do realize that. Have decided to go with the MPS-1 in a 5 channel configuration. Cool. I had seen that you mentioned the LPA-1 earlier and thought you were going with that. Enjoy that MPS-1! ;D If it were me and I was going with the MPS, I'd probably want a prepro with balanced outputs, otherwise I'd always play the 'what-if' game.

That's exactly what I was thinking but with Gonk's new thread I may have to take a wait and see approach. Was really planning on the MPS as a permanent addition to my setup and the LMC as a stepping stone, with the 40% upgrade deal. With all the comments about the LMC was second guessing that but now with the comments from Emotiva might have to reconsider. It would really suck if the updates pushed past the end of May which we all know is the end of free shipping !

Correction: with Gonk's reply to your new thread! Sorry, it's getting late and I was going from a memory that seems to be getting less reliable.

How can you check the firmware in the LMC-1?

Anyone hear\read news of a fully tested updated LMC-1 software\firmware? ? I'm ready to pull the trigger on the LMC-1 + LPA-1...maybe Dan can extend the free shipping for the Ultra Combo through June!? That way, Emotiva will be well assured of non-issue LMC units to their customers and will face a lower percentage of the 30-day policy returns!! Ted
