David,

Any time you reboot the Audio PC OS, you can lose connection to the NOS1.  Generally, the following has worked for me.
- Close XXHE
- Restart NOS1, either using the on/off switch at the back or resetting Switch #2 (I always mix us if this is #4 or #2--it is the one that turns the DAC off/on, not the battery switch)
- Make sure your DC offset is set correctly.
- Relaunch XXHE

You may sometimes need to reboot the Audio PC as well.

David,

Jogging my memory. The only thing I remember is a discussion related to the position of Switch #3 on the NOS1.  It was not specifically related to switching to high res formats. I do get a slight "tick" when this happens, but it's very soft.  I may be completely off here, but at one time there was potential for a loud pop related to leaving Switch #3 either up or down (I do not remember) for an extended period of time.  I'm assuming you are using the latest version of XXHE that fixed the "crack" detect issue that could also create a very loud pop.

Chad,

I've had this experience with other speakers, specifically the LX521 that needed a fair amount of distance from the front and side wall.  This has never been my experience with the Orelo.  What I like about them is that you can position them relatively close to the front and side walls--I think I was just too close.  I'm also trying to optimize for listening from multiple positions.  I've listened close and far back.  Different experiences.  The Orelo works well in both cases once the toe-in is set properly.  Too much toe-in was a problem I had.

Quick update.

I spent some time over the last days working on the placement of the Orelos.  The sound after some adjustments is definitely better.  Biggest improvement came from reducing toe-in, and moving the speakers a little forward (more distance from front wall).  Also by accident or good luck, I seem to have found a spot where the sound stage really has become 3D. 

- Speakers are 116" apart
- I listen on a sofa 132" away, and also from further back
- The back wall is quite a distance away (300" or more)
- Placement is asymmetric, because the L speaker is a the intersection of the living room and dining room, so no side wall nearby.  R speaker is very close to sidewall.

Sound is so good that my interest in experimentation is much is reduced.   

Peter,

Is the Pro version of the RME that you have?  I'm thinking of possibly getting one and experimenting.  The Linkwitz DSP people are using the minidsp Flex 8, which I think is quite limited.

I found the previous thread on this.  Linking it here again.

Arjan,

If you have another machine, you could insert the RAM drive SSD and see if the files are corrupted somehow.  Maybe run CHKDSK on the SSD drive. It does seem like you may have to get another RAM disk.  Did you backup any of the .vsd files?

Thanks Peter,

I'm up for trying and experimenting.  One help would be a good and accurate signal path diagram of what happens inside the Orelo from inputs to drivers.  I have notes from previous conversations, but if a diagram could be shared without disclosing any proprietary information, it would help to figure out options.  With the Linkwitz LX521s I still have, the crossovers and amps are external, which allows things to be upgraded including the drivers.

I know this will be a large project, and certainly should not be something that drains your time.  I have not tried to "open" the back or the nose of the Orelo to see what is going on inside, but maybe this could be done carefully.

Ramesh

Over the years we've seen many enhancements and upgrades to the XXHE PC (Mach II, Mach III), the NOS1 (B75, G3), cables (Lush, Blaxius, ET, XLR), and so on.  I haven't seen much regarding the Orelo MK II speakers.  Wondering if there are some avenues to try to make these sound even better. 

Arjan:

My Mach II has been on 24/7 more or less for at least a year now.   Very robust machine.  I often forget about the on/off switch at the back when I have moved the machine or unplugged it.  There are three switches on the Mach II as you know.  And the one on the side for the fan.

This is partly a comment and a question.

- For albums, there is typically an image "Folder.jpg" that is the cover art for the album.
- In "Playlist" folders, there is no cover art file.  And each file comes from a different album. How do media players find the cover art for these different tracks and albums?
- After I moved the folders, I no longer get the "CoverartPath is empty" message.  But also, I get the standard XXHE "X" cover art page when there is no cover art image.
- Playing the same files with Windows media player, the player seems to extract a cover art image even without any image file anywhere.

The problem is fixed doing the following:

- Create a new folder.  I called it "Compilations" instead of "Playlists".  I moved all the folders containing multiple tracks under this new folder.  I no longer get the error.  Something seems to have happened in resolving file paths that this simple process fixed.  Nik: perhaps you can try this.

Playing the playlist using Windows Media Player works fine, so wondering if this has something to do with how XXHE handles cover art for playlists where each track essentially has a different associated album cover.

When playing some newly prepared playlists, I get a dialog box saying "Check Cover Art" with the message "CoverartPath is empty".  This does not happen with albums, only with playlists.  Previously prepared playlists play fine.  Does anyone know what causes this error.  I can click "OK" and playback resumes, but it is a both when trying to play a long playlist.

Peter,

I was hoping to use these for RCA interconnects, not really concerned about 75 ohms.  This would not be for use with NOS1a, but as part of my HT system.  I've been using interconnects made with the Belden cable, and thought the Blaxius might be better for SQ.  I understand it is a bit of a job, so maybe I will just continue as is. 

The problem is that I have become so used to the Phasure system, that every time I listen to the HT setup I have, I keep trying to make it better.  Essentially, Mach II as player, Classe SSP-800 as processor, and now the old Linkwitz LX521 as speaker because I was concerned about LFE damaging the Orelo woofers.

Anyway, It's good to be listening to music again rather than speaking to analysts and investors!
