So - perhaps the solution that the DS products are taking with a streaming solution eliminates the problem of "noise" coming from external sources (ie computers) (assuming their products already eliminate the jitter problem)?

Same can be said of a Sonos, squeezebox or outboard sound card. Even an inboard card with some supply smoothing and good clock circuit could be fine. There's more to it. Everyone tries to eliminate jitter by reclocking for it's own DAC but it's not that easy to do correctly. Does it and is a dig out before or after a reclock as after would defeat the purpose. For an internal DAC, you have to apply the original clock accurately and the norm of PLLs can generally be bettered.
Any device that has access to the original file fits the profile but it certainly doesn't mean the dig out will be quiet and not resampled. If so, it would probably make a great source for the DAC as long as it's power supply isn't effecting the mains. Seems like quiet without interfernce is the key here. We'll see.

I really hope you are wrong!!

If the NAIM DAC preforms best with a CD player. This would imply that the TOS link is not delivering. Thus would vindicate all of those on the forum that have argued for a firewire interface!

For the moment - I take NAIM at their word. They've eliminated the issues associated with TOS - and my Mac is going to sound awesome! If it doesn't - there are alternatives - one of which is NOT buying a new CD front end or an HDX.

Gregg,

I agree. If performance is still 'connection' dependent - then it again argues in favor of the streaming solution. Ethernet is ethernet and all that.

Guess we all have to wait and see.

Not really. The other connections are still available including those from a TC(firewire). The problem with a direct firewire connection is PS noise and grounding. It's an imperfect world and there are few absolutes when dealing with such a veriety of sources and kit. If a TC sounds better than other ways, I'll report that but I've already discarded it own supply. If it sounds better with a TOS than something else that comes with 1394a, they win whether it can be made even better in other ways or not. I'd certainly try a glass cable regardless. Bandwith is maintained and an opaque plastic cable could increase noise if some reflection is present.
Some of this will always come down to perspective until the unit is auditioned and compared. At this point we're talking amateur theory here. LOL

how this it DAC compared to the one in SuperNait ?

On a scale from 1 to 10, if the Supernait one is a 5, would this one be a 8 ?

What level of performance do you think I can expect from an HDX, DAC & 555PS? As well, I suppose that now that we'll have a DAC, there's going to be all sorts of speculation as to which digital interconnect is going to work best with Naim. Perhaps a Naim cable is in the works.

There is the DC1

I think all assume it significantly better but until it's actually here, it will be hard to quantify.

maybe i have overseen it, but has someone thoughts about the possibilities of the i pod replay ?

i can´t imagine , that naim is creating so much attention just for the normal replay of mp3 files.does naim know something what we don´t know yet ? are any new ipods on the list which can maybe also replay flac ? as i understood it is a totally noise free replay.i also read , thats someone used i pods to play files from i tunes library stored on another apple computer ( like the mini). what if i pod could replay flac files soon and function as an streamer ? how much would this really influence the replay quality ? would it be a sonos in principal then ?

How good is the DC 1? Would it be best to stick with Naim cables between Naim gear?

None better that I've heard but It could vary matching with other kit. I suspect they'll do BNC terminations at some point too.

You can play wav quality files from an Ipod via lossless, wav or AIFF and it appears also by steam. Sonos can stream full wave files upto 16/44 also. The DAC is only seeing full wav format at the input from any of these sources. All decoading of inferior bitrates is done within the source device and not in any way being discussed as a replacement for non compressed files.

quote:

As the DAC is also buffering / re-clocking / it shouldn't matter what source software is used.

I'm no technical wizard (ok I know how aeroplanes work, including all the engine/nav/coms bits on them, and I can teach people these things) so I leave all the techy stuff to Naim and just listen. Now I KNOW that DACs turn 0's and 1's into music and it SHOULDN'T matter what supplies those 0's and 1's, nor SHOULD it matter if those 0's and 1's get delivered to the DAC slightly out of sync.............

...but my bloody ears keep telling me otherwise....every time I listen.

Can anybody explain THAT???

BTW I was at that BBQ last Friday and the DAC and Ovators sounded really good. Yes the dems were a bit compressed, yes Doug's music selections might not be to everybody's taste. But believe me, if you are in the market for a £2k DAC or a £6k pair of floorstanders, you owe it to yourself to arrange a proper demonstration.

According to the price list in the goodie bag last Friday, the DC1 is available in 4 versions.

DC1
DC1 BNC to BNC
DC1 RCA to BNC
DC1 BNC to RCA

All priced at £225

Don,

That has been mentioned several times on the Froum.

Just curious. What kind of music does Doug listen to?

js,

....if only....

Cheers

The White Paper is available for download - it has been mentioned elsewhere that a multipage brochure is also in existence. Can someone post this (perhaps Naim themselves) as a downloadable PDF?

Thanks

NO way.

He picked a fairly normal music ( Joni Michel Court and Spark ) after listening to my selections. :x

Gregg, not sure if this is what you're after, but there is a PDF flyer here courtesy of Signals...
