All you mention will run without problems. But what remains is the load on the "PC". One can well say that the more the relative (to the capacity) load is, the less the sonical outcome will be. If you, by the time, have two machines hanging around (prefarrably two Macs or two PCs), you can easily determine whether there's a difference. If there is, we always can see further, or ?

NOS1 requires filtering for redbook music. Good filtering is CPU intensive. Think that you want a decent computer for that purpose.

Well, this is the whole point where playback software differs to begin with;

If you can see any cpu useage (later) from XXHighEnd (XXEngine3.exe actually), just tell me. Happy

But since you are perfectly allowed to try/use other playback software, yes, be careful.

Apart from CAS, how is the sound of the DAC from digital in from CD transport? Assuming that the Software filter is not in use the sound is not as involving?
Thanks

Karma, you're going to find it pretty difficult connecting a CD transport to a NOS1. The original NOS1 needs a computer with a PCIe slot and the new USB NOS1 needs... you've guessed it... a USB connection. I don't know of a CD transport that has a USB connection as an output.

You can always use the computer's CD-ROM drive to play CDs of course. You can't do this with XXHighEnd, but something like HQPlayer would work fine. I've never tried this and have no idea how it would sound. I'm travelling for work at the moment but am happy to try this when I get back if you like. Though I strongly suspect your question was aimed at eliminating a computer altogether... Can't be done, as far as I know.

Cheers, Mani.

Cheers Mani,
That would be swell. Thank you for being the PR for Peter  Happy  I am here at Peter's cos of you.

New habits diehard. I have been a CAS user for more than 7 years - perhaps??? With my DAC202 I  was completely fedup and went digital. Hence my mind is still on CAS/Digital mode. Sure I can go back to CAS again, specially as this new special DAC is here! (Deja Vu? Had said the same before hearing, pushing down the cheque for the DAC202).

I spy another PC board on the DAC, can this accept any digital signal via suitable PC card? I wonder what the Hardware can do for the CDP? Perhaps tons - despite what I read about the digital filter,software side and the interface at the devils lair, I still read that the sound gets crazy after a suitable burn in. Hence teh CDP connection also sounds promising...

Cheers again

Hi there Karma, and ... a warm Welcome ! of course.

What people don't know is that I have an extended version of the NOS1-USB specs as well. This lists a few other possibilities, but it gold wild and I provided a simple one.

Think like about everything is possible, until we run out of input/output terminals (there are 12 possible in total with this cabinet). However, everything has to be created specifically for that first time, plus -and this is important- it will imply a load on the driver which is not preferrable. Not the most big deal, because I can provide as many driver versions as we need, and you could have one for normal playback, and another for ... well, playback from a transport via SPDIF-In. Of course, when you in ad-hoc fashion want to play a CD from the CDP this is not the most convenient, although uninstalling and re-installing takes maybe 2 minutes all together. But still, I think you'd *have* to do that for optimum sonic performance (without this latter one more general driver version will support more in one go).

I must also admit that I have been reluctant to tell about further options, because it will presumeably take ages of emails when not put out in the open to begin with, and/but no elementary option can have a standard price anyway because of a. efficieny in combinations and/or b. additional complexity because of the bunch of wires to solder it will take in the small space. Not working by "standards" also has its price.

By now, things having cooled down a bit, I may be up to it all, but the time it will take to really sort out things for the first time (because that is what it will be), is to be subtracted from the total capacity we have here, and which for sure at this time is not infinite (regarding the already too long pending orders).

Anyway, SPDIF-In is normally possible (not AES and no BNC connectors without further search for Neutrik fit), but at this time I don't even know what the maximum samle rate will be. Like for SPDIF-Out (also possible) this is 24/96, but which may well become 24/192 later.

Additional "complexity" arrives when we see that SPDIF-In can go via an internal SRC, or just without. Again driver settable, and don't ask me about the merits at this time.

Let's assume that such a connection takes 200 euros, then maybe you say "never mind". Good for me. Happy
But also note, please, that when this "first" costs 200 euros, a next may cost 50 euros because the main work has been spent ... as it can also cost 300 euros later because we then know what's really to be done. So, a vague thing at first always, and next there's this combination with other stuff.

It also can well be that we'll provide a few combination settings only. You know, those where you will be paying more than you asked for, but which makes life easier on our side.

Ok, I just scratched another of these more too wild possibilities, and actually I can't hold up. But I do for now anyway. Wink
But to keep in mind at all times : any of these options will come across as overpriced (mainly because of the driver work and sustaining the best SQ for the specific situation).

I'd say : When people have specific questions, let's ask them in this topic, which at least prevents from answering all the emails.

Regards,
Peter

Understood about the cost escalation and the incrimental, morphological, possibilities of this creation of yours. As Mani noted he will try, so will ; When I get my hands on your unit.

I am now waiting for your payment call and delivery date (sigh!!!6wks. unhappy )

Hello Peter and Cisca,

Hope all is well. Sounds like the last show was a success! How did the Ferrari Red DAC turn out? Would love to see pictures.
If Heaven smiles on us and we have some $$ to play with, I would love to get one of your DACS. If you make it back to the US, please look us up.
