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.   

I forgot to add this :

This is because you would fully eliminate your D/A converter of choice. Thus, the path would then be :

DAC -> MiniDSP-ADC -> DSP -> MiniDSP-DAC.

Yes, I have the Pro version.

The subject already reminded me of the allowed usage, which would be not using it for mid/high. So only the replacement of the Hypex would be allowed, hence for Bass only.

A schematic would be useless. Even telling in advance / in theory what to do is quite impossible. Taking out the Hypex would lead to something but it still would be a tedious job.

Something else is that I did not sort out the possibilities of the RME and if it can't bear 10 or so PEQs then it will be useless.
Also, for Bass only, MiniDSP would be sufficient IMO.

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.

Thanks Ramesh,

No backup. Will try CHKDSK but you might be right about this RAM-OS is lost.

Will see what I can do.

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.

Hi Peter,

When starting the PC I now get a selection screen to select e.g. W10-14393.0 RAM.

But next there are errors e.g. Error 16 Inconsistent filesystem structure.

Next option is to select another W10 version, but they all are returning this error.

So maybe the irreversible thing already happened. 

regards, Arjan

Hi Ramesh - good question.

Let me first say that relatively infinite design went into them, just because mechanical upgrade is, well, expensive. It's no NOS1 everybody shipped 5 or so times (and we back to you). Thus, we took measures in advance of desire for upgrade.

Sounds like BS, right ?
Yea, but I was there myself for - how long ? first one year for the Orphean filtering, next I think two years for the system as a whole, with as intermittent the Orelino (which Paul has).
Anyway, you can see it on the (crazy) possibilities of the electronics (mainly the input possibilities which you happily use yourself).

But

One of the more squeezing features is the DSP (including its unreliability as we know by now for already a long time). So what certainly is possible is replace the internal DSP with MiniDSP (there may be more). So that's 192KHz ADC rate - maybe more exists by now ? Or, some crazy thing I think of writing this ... what about the RME DAC /ADC (768 !) whith PEQ's via an app ?
One thing : this now has to be external. And would you care ?
I would not.

Again but :

But do I need it ? let's say that what one does not know, one does not need (this is a but of Dutch). So I myself never went that path.
It would require the experience with replacing a broken Hypex DSP in order to relatively easy figure out how to connect a new DSP, which always be external (just because it won't fit inside).
And then you'd have a plethora of new SQ options. Including DSP-control the mid and high.

This post (or yours) would be a first step out of many more and possibly also many $ more. But take it from me that really good options exist to replace all that resistors, coils and capacitors plus wires, with digital means. And this counts 100% positive when the ADC could be 786 - btw, I have one (RME ADI-2) which I only unboxed 2 months ago, after having it 2-3 years already. But mind you, that PEQ etc. app is only also 2 months new.

Regards and thanks you for the subject,
Peter
